LIPITOR is a synthetic
lipid-lowering agent. Atorvastatin is an inhibitor of
3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. This enzyme
catalyzes the conversion of HMG-CoA to mevalonate, an early andrate-limiting
step in cholesterol biosynthesis.
Atorvastatin calcium is [R-(R*,
R*)]-2-(4-fluorophenyl)-β,
δ-dihydroxy-5-(1-methylethyl)-3-phenyl-4-[(phenylamino)carbonyl]-1Hpyrrole-1-heptanoic
acid, calcium salt (2:1)trihydrate. The empirical formula of atorvastatin
calcium is(C33H34FN2O5)2Ca•3H2O
and its molecular weight is 1209.42. Its structural formula is:
Atorvastatin calcium is a white
to off-white crystalline powder that is insoluble in aqueous solutions of pH
4and below. Atorvastatin calcium is very slightly soluble in distilled water,
pH 7.4 phosphate buffer, and acetonitrile; slightly soluble in ethanol; and
freely soluble in methanol.
LIPITOR Tablets for oral
administration contain 10, 20, 40, or 80 mg of atorvastatin and the following
inactive ingredients: calcium carbonate, USP; candelilla wax,FCC;
croscarmellose sodium, NF; hydroxypropyl cellulose, NF; lactose monohydrate,
NF; magnesium stearate, NF; microcrystalline cellulose, NF; Opadry White
YS-1-7040(hypromellose, polyethylene glycol, talc, titanium dioxide);
polysorbate 80, NF; simethicone emulsion.
Indications
INDICATIONS
Therapy with lipid-alteringagents should be only one
component of multiple risk factor intervention in individuals at significantly
increased risk for atherosclerotic vascular diseasedue to hypercholesterolemia.
Drug therapy is recommended as an adjunct to diet when the response to a diet
restricted in saturated fat and cholesterol and other non-pharmacologic
measures alone has been inadequate. In patients with CHD or multiple risk factors
for CHD, LIPITOR can be started simultaneously with diet.
Prevention Of Cardiovascular
Disease In Adults
In adult patients without
clinically evident coronary heart disease, but with multiple risk factors for
coronary heart disease such as age, smoking, hypertension, low HDL-C, or a family
history of early coronary heart disease, LIPITOR is indicated to:
Reduce the risk of myocardial infarction
Reduce the risk of stroke
Reduce the risk for revascularization procedures and
angina
In adult patients with type 2 diabetes, and without
clinically evident coronary heart disease, but with multiple risk factors for
coronary heart disease such as retinopathy, albuminuria, smoking, or
hypertension, LIPITOR is indicated to:
Reduce the risk of myocardial infarction
Reduce the risk of stroke
In adult patients with clinically
evident coronary heart disease, LIPITOR is indicated to:
Reduce the risk of non-fatalmyocardial infarction
Reduce the risk of fatal and non-fatal stroke
Reduce the risk for revascularization procedures
Reduce the risk of hospitalization for CHF
Reduce the risk of angina
Hyperlipidemia
LIPITOR is indicated:
As an adjunct to diet to reduce elevated total-C, LDL-C,
apo B, and TGlevels and to increase HDL-C in adult patients with primary hypercholesterolemia
(heterozygous familial and non familial) and mixed dyslipidemia(Fredrickson Types
IIa and IIb);
As an adjunct to diet for the treatment of adult patients
with elevated serum TG levels (Fredrickson Type IV);
For the treatment of adult patients with primary
dysbetalipoproteinemia (Fredrickson Type III) who do not respond adequately to
diet;
To reduce total-C and LDL-Cin patients with homozygous
familial hypercholesterolemia(HoFH)as an adjunct to other lipid-lowering
treatments (e.g., LDL apheresis) or if such treatments are unavailable;
As an adjunct to diet to reduce total-C, LDL-C, and apo B
levels in pediatric patients, 10 years to 17 years of age, with heterozygous
familial hypercholesterolemia (HeFH)if after an adequate trial of diet therapy
the following findings are present:
LDL-C remains ≥ 190 mg/dL or
LDL-C remains ≥ 160 mg/dL and:
there is a positive family history of premature
cardiovascular disease or
two or more other CVD risk factors are present in the
pediatric patient
Limitations Of Use
LIPITOR has not been studied in conditions where the
major lipoprotein abnormality is elevation of chylomicrons(Fredrickson Types I
and V).
Dosage
DOSAGE AND ADMINISTRATION
Hyperlipidemia And Mixed
Dyslipidemia
The recommended starting dose
of LIPITOR is 10 or 20 mg once daily. Patients who require a large reduction in
LDL-C (more than 45%) may be started at 40 mg once daily. The dosage range of
LIPITOR is 10to 80mg once daily. LIPITOR can be administered as a single dose
at any time of the day, with or without food. The starting dose and maintenance
doses of LIPITOR should be individualized according to patient characteristics
such as goal of therapy and response. After initiation and/or upon titration of
LIPITOR, lipid levels should be analyzed within 2 to 4weeks and dosage adjusted
accordingly.
Heterozygous Familial
Hypercholesterolemia In Pediatric Patients (10Years to17Years of Age)
The recommended starting dose
of LIPITOR is 10 mg/day; the usual dose range is 10 to 20mg orally once daily [see
Clinical Studies]. Doses should be individualized according to the
recommended goal of therapy [see INDICATIONS AND USAGE and CLINICAL
PHARMACOLOGY]. Adjustments should be made at intervals of 4 weeks or
more.
Homozygous Familial
Hypercholesterolemia
The dosage of LIPITOR in patients
with HoFH is 10to 80mg daily. LIPITOR should be used as an adjunct to other
lipid-lowering treatments (e.g., LDL apheresis) in these patients or if such
treatments are unavailable.
Concomitant Lipid-Lowering
Therapy
LIPITOR may be used with bile acid
resins. The combination of HMG-CoA reductase inhibitors (statins) and fibrates should
generally be used with caution[see WARNINGS AND PRECAUTIONS and DRUG
INTERACTIONS].
Dosage In Patients With Renal
Impairment
Renal disease does not affect the
plasma concentrations nor LDL-Creduction of LIPITOR; thus, dosage adjustment in
patients with renal dysfunction is not necessary [see WARNINGS AND
PRECAUTIONS and CLINICAL PHARMACOLOGY].
Dosage In Patients Taking
Cyclosporine, Clarithromycin, Itraconazole, Or Certain Protease Inhibitors
In patients taking cyclosporine
or the HIV protease inhibitors (tipranavir plus ritonavir) or the hepatitis C
protease inhibitor (telaprevir), therapy with LIPITOR should be avoided. In
patients with HIV taking lopinavir plus ritonavir, caution should be used when
prescribing LIPITOR and the lowest dose necessary employed. In patients taking
clarithromycin, itraconazole, or in patients with HIV taking a combination of
saquinavir plus ritonavir, darunavir plus ritonavir, fosamprenavir, or
fosamprenavir plus ritonavir, therapy with LIPITOR should be limited to20 mg,
and appropriate clinical assessment is recommended to ensure that the lowest
dose necessary of LIPITOR is employed. In patients taking the HIV protease
inhibitornelfinaviror the hepatitis C protease inhibitor boceprevir, therapy
with LIPITOR should be limited to 40 mg, and appropriate clinical assessment is
recommended to ensure that the lowest dose necessary of LIPITOR is employed [see
WARNINGS AND PRECAUTIONS and DRUG INTERACTIONS].

The following serious adverse
reactions are discussed in greater detail in other sections of the label:
Rhabdomyolysis and myopathy [see
WARNINGS AND PRECAUTIONS]
Liver enzyme abnormalities [see
WARNINGS AND PRECAUTIONS]
Clinical Trials Experience
Because clinical trials are
conducted under widely varying conditions, the adverse reaction rates observed
in the clinical trials of a drug cannot be directly compared to rates in the
clinical trials of another drug and may not reflect the rates observed in
clinical practice.
In the LIPITOR
placebo-controlled clinical trial database of 16,066patients (8755 LIPITOR vs.
7311 placebo; age range 10-93 years, 39% women, 91% Caucasians, 3% Blacks, 2%
Asians, 4% other)with a median treatment duration of 53 weeks, 9.7% of patients
on LIPITOR and 9.5% of the patients on placebo discontinued due to adverse
reactions regardless of causality. The five most common adverse reactions in
patients treated with LIPITOR that led to treatment discontinuation and
occurred at a rate greater than placebo were: myalgia (0.7%), diarrhea (0.5%),
nausea (0.4%), alanine aminotransferase increase (0.4%), and hepatic enzyme
increase (0.4%).
The most commonly reported adverse
reactions(incidence ≥ 2%and greater than placebo) regardless of causality, in
patient streated with LIPITOR in placebo controlled trials (n=8755) were:
nasopharyngitis (8.3%), arthralgia (6.9%), diarrhea (6.8%), pain in extremity
(6.0%), and urinary tract infection (5.7%).
Table 3 summarizes the
frequency of clinicaladverse reactions, regardless of causality, reported in
≥ 2% and at a rate greater than placebo in patients treated with LIPITOR
(n=8755), from seventeen placebo-controlled trials.

Anglo-Scandinavian Cardiac
Outcomes Trial (ASCOT)
In ASCOT [see Clinical
Studies] involving 10,305 participants (age range 40-80 years, 19% women;
94.6% Caucasians, 2.6% Africans, 1.5% South Asians, 1.3% mixed/other) treated
with LIPITOR 10 mg daily (n=5,168) or placebo (n=5,137), the safety and
tolerability profile of the group treated with LIPITOR was comparable to that
of the group treated with placebo during a median of 3.3 years of follow-up.
Collaborative Atorvastatin
Diabetes Study (CARDS)
In CARDS [see Clinical
Studies] involving 2,838 subjects (age range 39-77 years, 32% women; 94.3%
Caucasians, 2.4% South Asians, 2.3% Afro-Caribbean, 1.0% other) with type 2
diabetes treated with LIPITOR 10 mg daily(n=1,428) or placebo (n=1,410), there
was no difference in the overall frequency of adverse reactions or serious
adverse reactions between the treatment groups during a median follow-up of 3.9
years. No cases of rhabdomyolysis were reported.
Treating to New Targets
Study(TNT)
In TNT [see Clinical Studies]
involving 10,001 subjects (age range 29-78 years, 19% women; 94.1% Caucasians,
2.9% Blacks, 1.0%Asians, 2.0% other) with clinically evident CHD treated with
LIPITOR10mg daily (n=5006) orLIPITOR80 mg daily (n=4995), there were more
serious adverse reactions and discontinuations due to adverse reactions in the
high-dose atorvastatin group (92, 1.8%; 497, 9.9%,respectively) as compared to
the low-dose group (69, 1.4%; 404, 8.1%, respectively) during a median
follow-up of 4.9 years. Persistent transaminase elevations ( ≥ 3x ULN twice
within 4-10days) occurred in 62 (1.3%) individuals with atorvastatin80mg
andinnine(0.2%)individualswithatorvastatin10mg.ElevationsofCK( ≥ 10x ULN)
were low overall, but were higher in the high-dose atorvastatin treatment group
(13, 0.3%) compared to the low-dose atorvastatin group (6, 0.1%).
Incremental Decrease in
Endpoints through Aggressive Lipid Lowering Study (IDEAL)
In IDEAL [see Clinical
Studies] involving 8,888 subjects (age range 26-80 years, 19% women; 99.3%
Caucasians, 0.4% Asians, 0.3% Blacks, 0.04% other) treated with LIPITOR80
mg/day (n=4439)or simvastatin 20-40 mg daily (n=4449), there was no difference
in the overall frequency of adverse reactions or serious adverse reactions
between the treatment groups during a median follow-up of 4.8 years.
Stroke Prevention by
Aggressive Reduction in Cholesterol Levels (SPARCL)
In SPARCL involving 4731
subjects (age range 21-92 years, 40% women; 93.3% Caucasians, 3.0% Blacks, 0.6%
Asians, 3.1% other) without clinically evident CHD but with a stroke or
transient ischemic attack (TIA) within the previous 6 months treated with
LIPITOR 80 mg (n=2365) or placebo (n=2366) for a median follow-up of 4.9 years,
there was a higher incidence of persistent hepatic transaminase elevations
( ≥ 3xULN twice within 4-10days) in the atorvastatin group (0.9%) compared
to placebo (0.1%). Elevations of CK ( > 10 x ULN) were rare, but were higher
in the atorvastatin group (0.1%) compared to placebo (0.0%). Diabetes was
reported as an adverse reaction in 144 subjects (6.1%) in the atorvastatin
group and 89 subjects (3.8%) in the placebo group [see WARNINGS AND
PRECAUTIONS].
In a post-hoc analysis, LIPITOR
80 mg reduced the incidence of ischemic stroke(218/2365, 9.2% vs. 274/2366, 11.6%)
and increased the incidence of hemorrhagic stroke (55/2365, 2.3% vs. 33/2366,
1.4%)compared to placebo. The incidence of fatal hemorrhagic stroke was similar
between groups (17LIPITOR vs. 18placebo). The incidence of non-fatal
hemorrhagic strokes was significantly greater in the atorvastatin group (38
non-fatal hemorrhagic strokes) as compared to the placebo group (16 non-fatal
hemorrhagic strokes). Subjects who entered the study with a hemorrhagic stroke
appeared to be at increased risk for hemorrhagic stroke [7 (16%) LIPITOR vs.2
(4%) placebo].
There were no significant
differences between the treatment groups for all-cause mortality: 216 (9.1%) in
the LIPITOR 80mg/day group vs. 211(8.9%)in the placebo group. The proportions
of subjects who experienced cardiovascular death were numerically smaller in
the LIPITOR80 mg group (3.3%) than in the placebo group (4.1%). The proportions
of subjects who experienced non-cardiovascular death were numerically larger in
the LIPITOR80 mg group (5.0%) than in the placebo group(4.0%).
Adverse Reactions From Clinical
Studies Of LIPITOR In Pediatric Patients
In a 26-weekcontrolled study in
boys and postmenarchal girls with HeFH (ages 10years to17 years)(n=140, 31%
female; 92% Caucasians, 1.6% Blacks, 1.6% Asians, 4.8% other), the safety and
tolerability profile of LIPITOR10 to 20mg daily, as an adjunct to diet to
reduce total cholesterol, LDL-C, and apoB levels, was generally similar to that
of placebo [see Use in Special Populations and Clinical Studies].
Postmarketing Experience
The following adverse reactions
have been identified during post-approval use of LIPITOR. Because these
reactions are reported voluntarily from a population of uncertain size, it is
not always possible to reliably estimate their frequency or establish a causal
relationship to drug exposure.
Adverse reactions associated
with LIPITOR therapy reported since market introduction, that are notlisted
above, regardless of causality assessment, include the following: anaphylaxis,
angioneurotic edema, bullous rashes (including erythema multiforme,
Stevens-Johnson syndrome, and toxic epidermal necrolysis), rhabdomyolysis, myositis,
fatigue, tendon rupture, fatal and non-fatal hepatic failure, dizziness,
depression, peripheral neuropathy, pancreatitis and interstitial lung disease.
There have been rare reports of
immune-mediated necrotizing myopathy associated with stat in use [see
WARNINGS AND PRECAUTIONS].
There have been rare
postmarketing reports of cognitive impairment (e.g., memory loss,
forgetfulness, amnesia, memory impairment, confusion) associated with statin
use. These cognitive issues have been reported for all statins. The reports
aregenerally nonserious, and reversible upon statin discontinuation, with
variable times to symptom onset (1 day to years) andsymptom resolution (median
of 3 weeks).
Drug Interactions
DRUG INTERACTIONS
The risk of myopathy during
treatment with statins is increased with concurrent administration of fibric
acid derivatives, lipid-modifying doses of niacin, cyclosporine, or strong CYP
3A4 inhibitors (e.g., clarithromycin, HIV protease inhibitors, and
itraconazole) [see WARNINGS AND PRECAUTIONS and CLINICAL PHARMACOLOGY].
Strong Inhibitors Of CYP 3A4
LIPITOR is metabolized by
cytochrome P450 3A4.Concomitant administration of LIPITOR with strong inhibitors
of CYP 3A4 can lead to increases in plasma concentrations of atorvastatin. The
extent of interaction and potentiation of effects depend on the variability of
effect on CYP 3A4.
Clarithromycin
Atorvastatin AUC was
significantly increased with concomitant administration of LIPITOR 80 mg with
clarithromycin (500mg twice daily)compared to that of LIPITOR alone [see CLINICAL
PHARMACOLOGY]. Therefore, in patients taking clarithromycin, caution should
be used when the LIPITOR dose exceeds 20mg [see DOSAGE AND ADMINISTRATION
and WARNINGS AND PRECAUTIONS].
Combination Of Protease Inhibitors
Atorvastatin AUC was
significantly increased with concomitant administration of LIPITOR with several
combinations of HIV protease inhibitors, as well as with the hepatitis C
protease inhibitor telaprevir, compared to that of LIPITOR alone [see CLINICAL
PHARMACOLOGY]. Therefore, in patients taking the HIV protease inhibitor tipranavir
plus ritonavir, or the hepatitis C protease inhibitor telaprevir, concomitant
use of LIPITOR should be avoided. In patients taking the HIV protease inhibitor
lopinavir plus ritonavir, caution should be used when prescribing LIPITOR and
the lowest dose necessary should be used. In patients taking the HIV protease
inhibitors saquinavir plus ritonavir, darunavir plus ritonavir, fosamprenavir,
or fosamprenavir plus ritonavir, the dose of LIPITOR should not exceed 20 mg
and should be used with caution [see DOSAGE AND ADMINISTRATION and WARNINGS
AND PRECAUTIONS]. In patients taking the HIV protease inhibitor nelfinavir
or the hepatitis C protease inhibitor boceprevir, the dose of LIPITOR should not
exceed 40 mg and close clinical monitoring is recommended.
Itraconazole
Atorvastatin AUC was
significantly increased with concomitant administration of LIPITOR 40 mg and
itraconazole200mg [see CLINICAL PHARMACOLOGY]. Therefore, in patients
taking itraconazole, caution should be used when the LIPITOR dose exceeds 20 mg
[see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS].
Grapefruit Juice
Contains one or more components
that inhibit CYP 3A4 and can increase plasma concentrations of atorvastatin,
especially with excessive grapefruit juice consumption ( > 1.2 liters per
day).
Cyclosporine
Atorvastatin and
atorvastatin-metabolites are substrates of the OATP1B1 transporter. Inhibitors
of the OATP1B1 (e.g., cyclosporine) can increase the bioavailability of
atorvastatin. Atorvastatin AUC was significantly increased with concomitant administration
of LIPITOR 10 mg and cyclosporine 5.2 mg/kg/day compared to that of LIPITOR alone
[see CLINICAL PHARMACOLOGY]. The co-administration of LIPITOR with
cyclosporine should be avoided[see WARNINGS AND PRECAUTIONS].
Gemfibrozil
Due to an increased risk of
myopathy/rhabdomyolysis when HMG-CoA reductase inhibitors are co-administered
with gemfibrozil, concomitant administration of LIPITOR with gemfibrozil should
be avoided [see WARNINGS AND PRECAUTIONS].
Other Fibrates
Because it is known that the
risk of myopathy during treatment with HMG-CoA reductase inhibitors is
increased with concurrent administration of other fibrates, LIPITOR should be
administered with caution when used concomitantly with other fibrates [see
WARNINGS AND PRECAUTIONS].
Niacin
The risk of skeletal muscle
effects may be enhanced when LIPITOR is used in combination with niacin; a
reduction in LIPITOR dosage should be considered in this setting [see
WARNINGS AND PRECAUTIONS].
Rifampin Or Other Inducers Of Cytochrome
P450 3A4
Concomitant administration of
LIPITOR with inducers of cytochrome P450 3A4 (e.g., efavirenz, rifampin) can
lead to variable reductionsin plasma concentrations of atorvastatin. Due to the
dual interaction mechanism of rifampin, simultaneous co-administration of
LIPITOR with rifampin is recommended, as delayed administration of LIPITOR
after administration of rifampin has been associated with a significant
reduction in atorvastatin plasma concentrations.
Digoxin
When multiple doses of LIPITOR
and digoxin were co-administered, steady state plasma digoxin concentrations
increased by approximately 20%. Patients takingdigoxin should be monitored
appropriately.
Oral Contraceptives
Co-administration of LIPITOR
and an oral contraceptive increased AUC values for norethindrone and ethinyl
estradiol[see CLINICAL PHARMACOLOGY].These increases should be
considered when selecting an oral contraceptive for a woman taking LIPITOR.
Warfarin
LIPITOR had no clinically
significant effect onprothrombin time when administered to patients receiving
chronic warfarin treatment.
Colchicine
Cases of myopathy, including
rhabdomyolysis, have been reported withatorvastatin co-administered with
colchicine, and caution should be exercised when prescribing atorvastatin with
colchicine.
Warnings & Precautions
WARNINGS
Included as part of the PRECAUTIONS section.
PRECAUTIONS
Skeletal Muscle
Rare cases of rhabdomyolysis
with acute renal failure secondary to myoglobinuria have been reported with LIPITOR
and with other drugs in this class. A
history of renal impairment may be a risk factor for the development of
rhabdomyolysis. Such patients merit closer monitoring for skeletal muscle
effects.
Atorvastatin, like other
statins, occasionally causes myopathy, defined as muscle aches or muscle
weakness in conjunction with increases in creatine phosphokinase (CPK) values
> 10 times ULN. The concomitant use of higher doses of atorvastatin with
certain drugs such as cyclosporine and strong CYP3A4 inhibitors (e.g., clarithromycin,
itraconazole, and HIV protease inhibitors) increases the risk of myopathy/rhabdomyolysis.
There have been rare reports of
immune-mediated necrotizing myopathy (IMNM), an autoimmune myopathy, associated
with statin use. IMNM is characterized by: proximalmuscle weakness and elevated
serum creatine kinase, which persist despite discontinuation of statin
treatment; muscle biopsy showing necrotizing myopathy without significant
inflammation; improvement with immunosuppressive agents.
Myopathy should be considered
in any patient with diffuse myalgias, muscle tenderness or weakness, and/or
marked elevation of CPK. Patients should be advised to report promptly
unexplained muscle pain, tenderness, or weakness, particularly if accompanied by
malaise or fever or if muscle signs and symptoms persist after discontinuing
LIPITOR. LIPITOR therapy should be discontinued if markedly elevated CPK levels
occur or myopathy is diagnosed or suspected.
The risk of myopathy during
treatment with drugs in this class is increased with concurrent administration
of cyclosporine, fibric acid derivatives, erythromycin, clarithromycin, the
hepatitis C protease inhibitor telaprevir, combinations of HIV protease
inhibitors, including saquinavir plus ritonavir, lopinavir plus ritonavir, tipranavir
plus ritonavir, darunavirplus ritonavir, fosamprenavir, and fosamprenavir plus
ritonavir, niacin, or azole antifungals. Physicians considering combined
therapy with LIPITOR and fibric acid derivatives, erythromycin, clarithromycin,
a combination ofsaquinavir plusritonavir, lopinavir plus ritonavir, darunavir plusritonavir,
fosamprenavir, or fosamprenavir plus ritonavir,azole antifungals, or
lipid-modifying doses of niacin should carefully weigh the potential benefits
and risks and should carefully monitor patients for any signs or symptoms of
muscle pain, tenderness, or weakness, particularly during the initial months of
therapy and during any periods of upward dosage titration of either drug. Lower
starting and maintenance doses of atorvastatin should be considered when taken
concomitantly with the aforementioned drugs [see DRUG INTERACTIONS].
Periodic creatine phosphokinase(CPK) determinations may be considered in such
situations, but there is no assurance that such monitoring will prevent the
occurrence of severe myopathy.
Prescribing recommendations for
interacting agents are summarized in Table2 [see DOSAGE AND ADMINISTRATION,
DRUG INTERACTIONS, and CLINICAL PHARMACOLOGY].

Cases of myopathy, including
rhabdomyolysis, have been reported with atorvastatinco-administered with
colchicine, and caution should be exercised when prescribing atorvastatin with
colchicine [see DRUG INTERACTIONS].
LIPITOR therapy should be
temporarily withheld or discontinued in any patient with anacute, serious
condition suggestive of a myopathy or having a risk factor predisposing to the
development of renal failure secondary to rhabdomyolysis(e.g., severe acute infection,
hypotension, major surgery, trauma, severe metabolic, endocrine and electrolyte
disorders, and uncontrolled seizures).
Liver Dysfunction
Statins, like some other
lipid-lowering therapies, have been associated with biochemical abnormalities
of liver function. Persistent elevations ( > 3times the upper limit of normal[ULN]
occurring on 2 or more occasions) in serum transaminases occurred in 0.7% of
patients who received LIPITOR in clinical trials. The incidence of these
abnormalities was 0.2%, 0.2%, 0.6%, and 2.3% for 10, 20, 40, and80 mg,
respectively.
One patient in clinical trials
developed jaundice. Increases in liver function tests (LFT) in other patients
were not associated with jaundice or other clinical signs or symptoms. Upon
dose reduction, drug interruption, or discontinuation, transaminase levels
returned to or near pretreatment levels without sequelae. Eighteen of 30
patients with persistent LFT elevations continued treatment with a reduced dose
of LIPITOR.
It is recommended that liver
enzyme tests be obtained prior to initiating therapy with LIPITOR and repeated
as clinically indicated. There have been rare post marketing reports of fatal
and non-fatal hepatic failure in patients taking statins, including
atorvastatin. If serious liver injury with clinical symptoms and/or
hyperbilirubinemia or jaundice occurs during treatment with LIPITOR, promptly
interrupt therapy. If an alternate etiologyis not found, do not restart LIPITOR.
LIPITOR should be used with
caution in patients who consume substantial quantities of alcohol and/or have a
history of liver disease. Active liver disease or unexplained persistent
transaminase elevations are contraindications to the use of LIPITOR [see
CONTRAINDICATIONS].
Endocrine Function
Increases in HbA1c and fasting serum
glucose levels have been reported with HMG-CoA reductase inhibitors, including
LIPITOR.
Statins interfere with
cholesterol synthesis and theoretically might blunt adrenal and/or gonadal
steroid production. Clinical studies have shown that LIPITOR does not reduce
basal plasma cortisol concentration or impair adrenal reserve. The effects of
statins on male fertility have not been studied in adequate numbers of
patients. The effects, if any, on the pituitary-gonadal axis in premenopausal
women are unknown. Caution should be exercised if a statin is administered
concomitantly with drugs that may decrease the levels or activity of endogenous
steroidhormones, such as ketoconazole, spironolactone, and cimetidine.
CNS Toxicity
Brain hemorrhage was seen in a
female dog treated for 3 months at 120 mg/kg/day. Brain hemorrhage and optic
nerve vacuolation were seen in another female dog that was sacrificed in
moribund condition after 11 weeks of escalating doses up to 280 mg/kg/day. The
120mg/kg doseresulted in a systemic exposure approximately 16times the human
plasma area-under-the-curve (AUC, 0-24 hours) based on the maximum human dose
of 80 mg/day. A single tonic convulsion was seen in each of 2 male dogs (one
treated at 10 mg/kg/day and one at 120 mg/kg/day) in a 2-year study. No CNS
lesions have been observed in mice after chronic treatment for up to 2years at
doses up to 400 mg/kg/day or in rats at doses upto 100 mg/kg/day. These doses
were 6 to 11times (mouse) and 8 to 16 times (rat) the human AUC (0-24) based on
the maximum recommended human dose of 80mg/day.
CNS vascular lesions,
characterized by perivascular hemorrhages, edema, and mononuclear cell
infiltration of perivascular spaces, have been observed in dogs treated with
other members of this class. A chemically similar drug in this class produced
optic nerve degeneration (Wallerian degeneration of retinogeniculate fibers) in
clinically normal dogs in a dose-dependent fashion at a dose that produced
plasma drug levels about 30 times higher than the mean drug level in humans
taking the highest recommended dose.
Use In Patients With Recent
Stroke Or TIA
In a post-hoc analysis of the
Stroke Prevention by Aggressive Reduction in Cholesterol Levels (SPARCL) study
where LIPITOR 80 mg vs. placebo was administered in 4,731subjects without CHD
who had a stroke or TIA within the preceding 6 months, a higher incidence of
hemorrhagic stroke was seen in the LIPITOR80mg group compared to placebo (55,
2.3%atorvastatin vs. 33, 1.4% placebo; HR: 1.68, 95%CI:1.09,2.59;p=0.0168).The
incidence of fatal hemorrhagic stroke was similar across treatment groups (17
vs. 18 for the atorvastatin and placebo groups, respectively). The incidence of
nonfatal hemorrhagic stroke was significantly higher in the atorvastatin group
(38, 1.6%)as compared to the placebo group (16, 0.7%). Some baseline
characteristics, including hemorrhagic and lacunar stroke on study entry, were
associated with a higher incidence of hemorrhagic stroke in the atorvastatin
group [see ADVERSE REACTIONS].
Patient Counseling Information
Advise the patient to read the
FDA-approved patient labeling (PATIENT INFORMATION).
Patients taking LIPITOR
shouldbe advised that cholesterol is a chronic condition and they should adhere
to their medication along with their National Cholesterol Education Program
(NCEP)-recommended diet, a regular exercise program as appropriate, and
periodic testing of a fasting lipid panel to determine goal attainment.
Patients should be advised
about substances they should not take concomitantly with atorvastatin [see WARNINGS AND PRECAUTIONS].
Patients should also be advised to in for mother healthcare professionals
prescribing a new medication that they are taking LIPITOR.
Muscle Pain
All patients starting therapy
with LIPITOR should be advised of the risk of myopathy and told to report
promptly any unexplained muscle pain, tenderness, or weakness particularly if
accompanied by malaise or fever or if these muscle signs or symptoms persist
after discontinuing LIPITOR. The risk of this occurring is increased when
taking certain types of medication or consuming larger quantities ( > 1liter)
of grapefruit juice. They should discuss all medication, both prescription and
over the counter, with their healthcare professional.
Liver Enzymes
It is recommended that liver enzyme
tests be performed before the initiation of LIPITOR and if signs or symptoms of
liver injury occur. All patients treated with LIPITOR should be advised to
report promptly any symptoms that may indicate liver injury, including fatigue,
anorexia, right upper abdominal discomfort, dark urine, or jaundice.
Embryofetal Toxicity
Advise females of reproductive
potential of the risk to a fetus, to use effective contraception during
treatment and to inform their healthcare provider of a known or suspected
pregnancy [see CONTRAINDICATIONS and Use in Specific Populations].
Lactation
Advise women not to breastfeed
during treatment with LIPITOR[see CONTRAINDICATIONS and Use in
Specific Populations].
Nonclinical Toxicology
Carcinogenesis, Mutagenesis,
Impairment Of Fertility
In a 2-year carcinogenicity
study in rats at dose levels of 10, 30, and100mg/kg/day, 2 rare tumors were
found in muscle in high-dose females: in one, there was a rhabdomyosarcoma and,
in another, there was a fibrosarcoma. This dose represents a plasma AUC (0-24)
value of approximately 16times the mean human plasma drug exposure after an 80
mg oraldose.
A 2-year carcinogenicity
studyin mice given 100,200, or 400 mg/kg/day resulted in a significant increase
in liver adenomas in high-dose males and liver carcinomas in high-dose females.
These findings occurred at plasma AUC(0-24) values of approximately 6times the
mean human plasma drug exposure after an 80 mg oral dose.
In vitro, atorvastatin was not mutagenic or clastogenic in the
following tests with and without metabolic activation: the Ames test with Salmonella
typhimurium and Escherichia coli, the HGPRT forward mutation assay in Chinese
hamster lung cells, and the chromosomal aberration assay in Chinese hamster
lung cells. Atorvastatin was negativein the in vivo mouse micronucleus test.
In female rats, atorvastatinat
doses up to 225 mg/kg (56 times the human exposure) did not cause adverse
effectson fertility. Studies in male rats performed at doses up to 175 mg/kg
(15 times the human exposure) produced no changes in fertility. There was
aplasia and aspermia in the epididymis of 2 of 10rats treated with 100
mg/kg/dayof atorvastatinfor 3 months (16 times the human AUC at the 80mg dose);
testis weights were significantly lower at 30 and 100mg/kg and epididymal
weight was lower at 100mg/kg. Male rats given 100 mg/kg/day for 11 weeks prior
to mating had decreased sperm motility, spermatid head concentration, and
increased abnormal sperm. Atorvastatin caused no adverse effects on semen
parameters, or reproductive organ histopathology in dogs given doses of 10, 40,
or 120 mg/kg for two years.
Use In Specific Populations
Pregnancy
Risk Summary
LIPITOR is contraindicated for use in pregnant women since
safety in pregnant women has not been established and there is no apparent
benefit of lipid lowering drugs during pregnancy. Because HMG-CoA reductase
inhibitors decrease cholesterol synthesis and possibly the synthesis of other
biologically active substances derived from cholesterol, LIPITOR may cause fetal
harm when administered to a pregnant woman. LIPITOR should be discontinued as
soon as pregnancy is recognized [see CONTRAINDICATIONS]. Limited
published data on the use of atorvastatin are insufficient to determine a drug-associated
risk of major congenital malformations or miscarriage. In animal reproduction
studies in rats and rabbits there was no evidence of embryo-fetal toxicity or congenital
malformation sat doses up to 30 and 20 times, respectively, the human exposure at
the maximum recommended human dose (MRHD)of 80 mg, based on body surface area
(mg/m²). In rats administered atorvastatin during gestation and lactation,
decreased postnatal growth and development was observed at doses ≥ 6 times
the MRHD (see Data).
The estimated back ground risk of major birth defects and
miscarriage for the indicated population is unknown. In the U.S. general
population, the estimated background risk of major birth defects and
miscarriage in clinically recognized pregnancies is 2-4% and 1520%,
respectively.
Data
Human Data
Limited published data on
atorvastatin calcium from observational studies, meta-analyses and case report shave
not shown an increased risk of major congenital malformations or miscarriage.
Rare reports of congenital anomalies have been received following intrauterine
exposure to other HMG-CoA reductase inhibitors. In a review of approximately
100 prospectively followed pregnancies in women exposed to simvastatin or
lovastatin, the incidences of congenital anomalies, spontaneous abortions, and
fetal deaths/stillbirths did not exceed what would be expected in the general
population. The number of cases is adequate to exclude a ≥ 3to 4-fold
increase in congenital anomalies over the background incidence. In 89% of the
prospectively followed pregnancies, drug treatment was initiated prior to
pregnancy and was discontinued at some point in the first trimester when
pregnancy was identified.
Animal Data
Atorvastatin crosses the rat
placenta and reaches a level in fetal liver equivalent to that of maternal
plasma. Atorvastatin was administered to pregnant rats and rabbits during
organogenesis at oral doses up to 300mg/kg/day and 100mg/kg/day, respectively.
Atorvastatin was notteratogenic in rats at doses up to 300mg/kg/day or in
rabbits at doses up to 100mg/kg/day. These doses resulted in multiples of about
30 times (rat) or20 times (rabbit) the human exposure at the MRHD based on surface
area (mg/m²).In rats, the maternally toxic dose of 300mg/kg resulted in
increased post-implantation loss and decreased fetal body weight. At the
maternally toxic doses of 50 and 100mg/kg/day in rabbits, there was increased post-implantation
loss, and at 100mg/kg/day fetal body weights were decreased.
In a study
inpregnantratsadministered20, 100, or 225 mg/kg/day from gestation day7 through
to lactation day20(weaning), there was decreased survival at birth, postnatal
day 4, weaning, and post-weaning in pups of mothers dosed with 225mg/kg/day, a
dose at which maternal toxicity was observed. Pup body weight was decreased through
postnatal day 21at 100 mg/kg/day, and through postnatal day91 at 225 mg/kg/day.
Pup development was delayed (rotorod performance at 100mg/kg/day and acoustic
startle at 225 mg/kg/day; pinnae detachment and eye-opening at 225mg/kg/day).
These doses correspond to 6 times (100 mg/kg) and 22times (225 mg/kg) the human
exposure at the MRHD, based on AUC.
Lactation
Risk Summary
LIPITOR use is contraindicated
during breastfeeding [see CONTRAINDICATIONS]. There is no available
information on the effects of the drug on the breastfed infant or the effects
of the drug on milk production. It is not known whether at orvastatin is
present in human milk, but it has been shown that another drug in this class passes
into human milk and at orvastatin is present in rat milk. Because of the
potential for serious adverse reactions in a breastfedinfant, advise women that
breastfeeding is not recommended during treatment with LIPITOR.
Females And Males Of Reproductive
Potential
Contraception
LIPITOR may cause fetal harm
when administered to a pregnant woman. Advise females of reproductive potential
to use effective contraception during treatment with LIPITOR [see Use in
Specific Populations].
Pediatric Use
Heterozygous Familial
Hypercholesterolemia(HeFH)
The safety and effectiveness of
LIPITOR have been established in pediatric patients,10years to 17 years of age,
with HeFH as an adjunct to diet to reduce total cholesterol, LDL-C, and apoB
levels when, after an adequate trial of diet therapy, the following are
present:
LDL-C ≥ 190 mg/dL, or
LDL-C ≥ 160 mg/Dl and
A positive family history of FH, or premature CVD in a
first, or second-degree relative, or
two or more other CVD risk factors are present.
Use of LIPITOR for this
indication is supported by evidence from[see DOSAGE AND ADMINISTRATION, ADVERSE
REACTIONS, CLINICAL PHARMACOLOGY, and Clinical Studies]:
A placebo-controlled clinical trial of 6 months duration
in 187 boys and postmenarchal girls,10 years to 17 years of age. Patients
treated with 10 mg or20 mg daily LIPITOR had an adverse reaction profile
generally similar to that of patients treated with placebo. In this limited
controlled study, there was no significant effect on growth or sexual
maturation in boys or on menstrual cycle length in girls.
A three year open-label uncontrolled trial that
included163 pediatric patients 10 to 15years of age with HeFH who were titrated
to achieve a target LDL-C < 130 mg/dL. The safety and efficacy of LIPITOR in
lowering LDL-C appeared generally consistent with that observed for adult
patients, despite limitations of the uncontrolled study design
Advise postmenarchal girls of
contraception recommendations, if appropriate for the patient [see Use in
Specific Populations].
The long-term efficacy of LIPITOR
therapy initiated inchild hood to reduce morbidity and mortality in adulthood
has not been established.
The safety and efficacy of LIPITOR
have not been established in pediatric patients younger than 10 years of age with
HeFH.
Homozygous Familial
Hypercholesterolemia (HoFH)
Clinical efficacy of LIPITOR
with dosages up to 80mg/day for 1 year was evaluated in an uncontrolled study
of patients with HoFH including 8 pediatric patients [see Clinical Studies].
Geriatric Use
Of the 39,828 patients who received LIPITOR in clinical studies,
15,813(40%)were ≥ 65 years old and 2,800 (7%) were ≥ 75 years old. No
overall differences in safety or effectiveness were observed between these
subjects and younger subjects, and other reported
clinical experience has not
identified differences in responses between the elderly and younger patients,
but greater sensitivity of someolder adults cannot be ruled out. Since advanced
age ( ≥ 65 years) is a predisposing factor for myopathy, LIPITOR should be
prescribed with caution in the elderly.
Hepatic Impairment
Lipitor is contraindicated in
patients with active liver disease which may include unexplained persistent
elevations in hepatic transaminase levels [see CONTRAINDICATIONS and CLINICAL
PHARMACOLOGY].
Overdosage & Contraindications
OVERDOSE
There is no specific treatment
for LIPITOR overdosage. In the event of an overdose, the patient should be
treated symptomatically, and supportive measures instituted as required. Due to
extensive drug binding to plasma proteins, hemodialysis is not expected to
significantly enhance LIPITOR clearance.
CONTRAINDICATIONS
Active Liver Disease, Which May Include Unexplained Persistent
Elevations in Hepatic Transaminase Levels
Hypersensitivity to Any Component of This Medication
Pregnancy [see Use in Specific Populations].
Lactation [see Use in Specific Populations].
Clinical Pharmacology
CLINICAL PHARMACOLOGY
Mechanism Of Action
LIPITOR is a selective,
competitive inhibitor of HMG-CoA reductase, the rate-limiting enzyme that
converts 3-hydroxy-3methylglutaryl-coenzyme A to mevalonate, a precursor of
sterols, including cholesterol. In animal models, LIPITOR lowers plasma
cholesterol and lipoprotein levels by inhibiting HMG-CoA reductase and
cholesterol synthesis in the liver and by increasing the number of hepatic LDL
receptors on the cell surface to enhance uptake and catabolism of LDL; LIPITOR
also reduces LDL production and the number of LDL particles.
Pharmacodynamics
LIPITOR, as well as some of its
metabolites, are pharmacologically active in humans. The liver is the primary
site of action and the principal site of cholesterol synthesis and LDL
clearance. Drug dosage, rather than systemic drug concentration, correlates
better with LDL-C reduction. Individualization of drug dosage should be based
on therapeutic response[see DOSAGE AND ADMINISTRATION].
Pharmacokinetics
Absorption
LIPITOR is rapidly absorbed
after oral administration; maximum plasma concentrations occur within 1 to
2hours. Extent of absorption increases in proportion to LIPITOR dose. The
absolute bioavailability of atorvastatin(parent drug) is approximately 14% and
the systemic availability of HMG-CoA reductase inhibitory activity is
approximately 30%. The low systemic availability is attributed to presystemic
clearance in gastrointestinal mucosa and/or hepatic first-pass metabolism.
Although food decreases the rate and extent of drug absorption by approximately
25% and 9%, respectively, as assessed by Cmax and AUC, LDL-C reduction is
similar whether LIPITOR is given with or without food. Plasma LIPITOR concentrations
are lower (approximately 30% for Cmax and AUC) following evening drug
administration compared with morning. However, LDL-C reduction is the same
regardless of the time of day of drug administration [see DOSAGE AND
ADMINISTRATION].
Distribution
Mean volume of distribution of LIPITOR
is approximately 381 liters. LIPITOR is ≥ 98% bound to plasma proteins. A
blood/plasma ratio of approximately 0.25 indicates poor drug penetration into
red blood cells. Based on observations in rats, LIPITOR is likely to be
secreted in human milk [see CONTRAINDICATIONS and Use in Specific
Populations].
Metabolism
LIPITOR is extensively
metabolized to ortho-and parahydroxylated derivatives and various beta-oxidation
products. In vitro inhibition of HMG-CoA reductase by ortho-and
parahydroxylated metabolites is equivalent to that of LIPITOR. Approximately
70% of circulating inhibitory activity for HMG-CoA reductase is attributed to active
metabolites. In vitro studies suggest the importance of LIPITOR metabolism by
cytochrome P450 3A4, consistent with increased plasma concentrations of LIPITOR
in humans following co-administration with erythromycin, a known inhibitor of
this isozyme [see DRUG INTERACTIONS]. In animals, the ortho-hydroxy
metabolite undergoes further glucuronidation.
Excretion
LIPITOR and its metabolites are
eliminated primarily in bile following hepatic and/or extra-hepatic metabolism;
however, the drug does not appear to undergo enterohepatic recirculation. Mean
plasma elimination half-life of LIPITOR in humans is approximately 14hours, but
the half-life of inhibitory activity for HMG-CoA reductase is 20 to 30hours due
to the contribution of active metabolites. Less than2% of a dose of LIPITOR is
recovered in urine following oral administration.
Specific Populations
Geriatric: Plasma concentrations of
LIPITOR are higher (approximately 40% for Cmax and 30% for AUC)in healthy
elderly subjects(age ≥ 65years)than in young adults. Clinical data suggest a
greater degree of LDL-lowering at any dose of drug in the elderly patient
population compared to younger adults [see Use in Specific Populations].
Pediatric: Apparent oral clearance
of atorvastatin in pediatric subjects appeared similar to that of adults when
scaled allometrically by body weight as the body weight was the only
significant covariate in atorvastatin population PK model with data including pediatric
HeFH patients (ages 10years to 17years of age, n=29) in an open-label, 8-week
study.
Gender: Plasma concentrations of
LIPITOR in women differ from those in men (approximately 20% higher for Cmax
and 10% lower for AUC); however, there is no clinically significant difference
in LDL-C reduction with LIPITOR between men and women.
Renal Impairment: Renal disease has no
influence on the plasma concentrations or LDL-C reduction of LIPITOR; thus,
dose adjustment in patients with renal dysfunction is not necessary [see DOSAGE
AND ADMINISTRATION and WARNINGS AND PRECAUTIONS].
Hemodialysis: While studies have not been conducted in patients with
end-stage renal disease, hemodialysis is not expected to significantly enhance
clearance of LIPITOR since the drug is extensively bound to plasma proteins.
Hepatic Impairment: In patients with chronic
alcoholic liver disease, plasma concentrations of LIPITOR are markedly
increased. Cmax and AUC are each 4-fold greater in patients with Childs-Pugh A
disease. Cmax and AUC are approximately 16-fold and 11-fold increased,
respectively, in patients with Childs-Pugh B disease [see CONTRAINDICATIONS].

Clinical Studies
Prevention Of Cardiovascular
Disease
In the Anglo-Scandinavian
Cardiac Outcomes Trial (ASCOT), the effect of LIPITOR on fatal and non-fatal
coronary heart disease was assessed in 10,305 hypertensive patients 40-80 years
of age (mean of 63years), without a previous myocardial infarction and with TC levels
≤ 251mg/dL (6.5mmol/L). Additionally, all patients had at least 3 of the following
cardiovascular risk factors: male gender (81.1%), age > 55years
(84.5%),smoking (33.2%),diabetes (24.3%), history of CHD in a first-degree
relative (26%), TC:HDL > 6 (14.3%), peripheral vascular disease (5.1%), left
ventricular hypertrophy (14.4%), prior cerebrovascular event (9.8%), specific
ECG abnormality (14.3%), proteinuria/albuminuria (62.4%). In this double-blind,
placebo-controlled study, patients were treated with anti-hypertensive therapy
(Goal BP < 140/90 mmHg for non-diabetic patients; < 130/80 mmHg for diabetic
patients) and allocated to either LIPITOR10mg daily (n=5168) or placebo
(n=5137), using a covariate adaptive method which took into account the
distribution of nine baseline characteristics of patients already enrolled and
minimized the imbalance of those characteristics across the groups. Patients
were followed for a median duration of 3.3 years.
The effect of 10mg/day of
LIPITOR on lipid levels was similar to that seen in previous clinical trials.
LIPITOR significantly reduced
the rate of coronary events [either fatal coronary heart disease (46 events in
the placebo group vs. 40 events in the LIPITOR group) or non-fatal MI (108
events in the placebo group vs. 60 events in the LIPITOR group)] with a
relative risk reduction of 36% [(based on incidences of 1.9% for LIPITOR vs.
3.0% for placebo), p=0.0005 (see Figure 1)].The risk reduction was consistent
regardless of age, smoking status, obesity, or presence of renal dysfunction.
The effect of LIPITOR was seen regardless of baseline LDL levels. Due to the
small number of events, results for women were inconclusive.
Figure 1: Effect of LIPITOR
10 mg/day on Cumulative Incidence of Non-Fatal Myocardial Infarction or Coronary
Heart Disease Death (in ASCOT-LLA)
LIPITOR also significantly decreased the relative risk
for revascularization procedures by 42%(incidences of 1.4% for LIPITOR and 2.5%
for placebo). Although the reduction of fatal and non-fatal strokes did not reach
a pre-defined significance level (p=0.01), a favorable trend was observed with
a 26% relative risk reduction (incidences of 1.7% for LIPITOR and 2.3% for
placebo). There was no significant difference between the treatment groups for
death due to cardiovascular causes (p=0.51) or non-cardiovascular causes
(p=0.17).
In the Collaborative Atorvastatin Diabetes Study (CARDS),
the effect of LIPITOR on cardiovascular disease (CVD)endpoints was assessed in
2838subjects (94%white, 68% male), ages 40-75with type 2 diabetes based on WHO
criteria, without prior history of cardiovascular disease and with LDL ≤
160 mg/dL and TG ≤ 600 mg/dL. In addition to diabetes, subjects had 1 or
more of the following risk factors: current smoking(23%), hypertension (80%),
retinopathy (30%), or microalbuminuria (9%) or macroalbuminuria (3%). No
subjects on hemodialysis were enrolled in the study. In this multicenter,
placebo-controlled, double-blind clinicaltrial, subjects were randomly
allocated to either LIPITOR 10mg daily (1429) or placebo (1411) ina1:1ratio and
were followed for a median duration of 3.9 years. The primary endpoint was the
occurrence of any of the major cardiovascular events: myocardial infarction,
acute CHD death, unstableangina, coronary revascularization, or stroke. The
primary analysis was the time to first occurrence of the primary endpoint.
Baseline characteristics of subjects were: mean age of 62
years, mean HbA1c7.7%; median LDL-C 120
mg/dL; median TC 207 mg/dL; median TG 151 mg/dL; median HDL-C 52 mg/dL.
The effect of LIPITOR 10mg/day on lipid levels was
similar to that seen in previous clinical trials.
LIPITOR significantly reduced the rate of major
cardiovascular events (primary endpoint events) (83 events in the LIPITOR group
vs. 127events in the placebo group) with a relative risk reduction of 37%,
HR0.63,95%CI(0.48, 0.83)(p=0.001)(see Figure 2). An effect of LIPITOR was seen
regardless of age, sex, or baseline lipid levels.
LIPITOR significantly reduced the risk of stroke by 48%
(21events in the LIPITOR group vs. 39 events in the placebo group), HR 0.52,
95% CI (0.31, 0.89) (p=0.016) and reduced the risk of MI by 42%(38 events in
the LIPITOR group vs. 64 events in the placebo group), HR 0.58,95.1%CI(0.39,
0.86)(p=0.007).There was no significant difference between the treatment groups
for angina, revascularization procedures, and acute CHD death.
There were 61deaths in the LIPITOR group vs. 82 deaths in
the placebo group (HR 0.73, p=0.059).

In the Treating to New Targets Study
(TNT), the effect of LIPITOR80 mg/day vs. LIPITOR10 mg/day on the reduction in
cardiovascular events was assessed in 10,001 subjects (94% white, 81% male, 38%
≥ 65 years) with clinically evident coronary heart disease who had
achieved a target LDL-C level < 130 mg/dL after completing an 8-week,
open-label, run-in period with LIPITOR 10 mg/day. Subjects were randomly
assigned to either 10 mg/day or 80 mg/day of LIPITOR and followed for a median
duration of 4.9 years. The primary endpoint was the time-to-first occurrence of
any of the following major cardiovascular events (MCVE):death due to CHD,
non-fatal myocardial infarction, resuscitated cardiacarrest, and fatal and
non-fatal stroke. The mean LDL-C, TC, TG, non-HDL, and HDL cholesterol levels
at 12 weeks were 73,145,128,98,and 47mg/dL during treatment with 80 mg of
LIPITOR and 99, 177, 152, 129, and 48mg/dL during treatment with 10mg of LIPITOR.
Treatment with LIPITOR80mg/day
significantly reduced the rate of MCVE(434 events in the 80 mg/day group vs.
548eventsin the 10 mg/day group) with a relative risk reduction of 22%,
HR0.78,95%CI(0.69, 0.89),p=0.0002(see Figure 3 and Table6). The
overallrisk reduction was
consistent regardless of age( < 65, ≥ 65) or gender.

Secondary Endpoints were not adjusted for multiple comparisons
Of the events that comprised the primary efficacy
endpoint, treatment with LIPITOR 80 mg/day significantly reduced the rate of
nonfatal, non-procedure related MI and fatal and non-fatal stroke, but not CHD
death or resuscitated cardiac arrest (Table6). Of the predefined secondary
endpoints, treatment with LIPITOR 80 mg/day significantly reduced the rate of
coronary revascularization, angina, and hospitalization for heart failure, but
not peripheral vascular disease. The reduction in the rate of CHF with
hospitalization was only observed in the 8% of patients with a prior history of
CHF.
There was no significant difference between the treatment
groups for all-cause mortality (Table6). The proportions of subjects who
experienced cardiovascular death, including the components of CHD death and fatal
stroke, were numerically smaller in the LIPITOR 80 mg group than in the LIPITOR
10 mg treatment group. The proportions of subjects who experienced non-cardiovascular
death were numerically larger in the LIPITOR80 mg group than in the LIPITOR 10
mg treatment group.
In the Incremental Decrease in
Endpoints Through Aggressive Lipid Lowering Study (IDEAL), treatment with
LIPITOR80mg/day was compared to treatment with simvastatin 20-40 mg/day in
8,888 subjects up to80 years of age with a history of CHD to assess whether
reduction in CV risk could be achieved. Patients were mainly male (81%), white
(99%) with an average age of 61.7years, and an average LDL-Cof121.5 mg/dL at
randomization; 76% were on stat in therapy. In this prospective, randomized,
open-label, blinded endpoint (PROBE)trial with no run-in period, subjects were
followed for a median duration of 4.8 years. The mean LDL-C, TC, TG, HDL, and
non-HDL cholesterol levels at Week 12 were 78,145, 115, 45, and 100mg/dL during
treatment with 80 mg of LIPITOR and105,179, 142, 47, and 132mg/dL during
treatment with 20-40 mg of simvastatin.
There was no significant
difference between the treatment groups for the primary endpoint, the rate of
first major coronary event (fatal CHD, non-fatal MI, and resuscitated cardiac
arrest): 411 (9.3%) in the LIPITOR80 mg/day group vs. 463 (10.4%) in the
simvastatin 20-40 mg/day group, HR 0.89, 95% CI ( 0.78, 1.01), p=0.07.
There were no significant
differences between the treatment groups for all-cause mortality: 366 (8.2%) in
the LIPITOR 80mg/day group vs. 374(8.4%)in the simvastatin 20-40 mg/day group.
The proportions of subjects who experienced CV or non-CV death were similar for
the LIPITOR 80 mg group and the simvastatin 20-40 mg group.
Hyperlipidemia And Mixed
Dyslipidemia
LIPITOR reduces total-C, LDL-C,
VLDL-C, apo B, and TG, and increases HDL-C in patients with hyperlipidemia (heterozygous
familial and non familial)and mixed dyslipidemia(Fredrickson Types IIa and
IIb). Therapeutic response is seen within 2 weeks, and maximum response is
usually achieved within 4 weeks and maintained during chronic therapy.
LIPITOR is effective in a wide
variety of patient populations with hyperlipidemia, with and without
hypertriglyceridemia, in men and women, and in the elderly.
In two multicenter,
placebo-controlled, dose-response studies in patients with hyperlipidemia,
LIPITOR given as a single doseover 6weeks,significantly reduced total-C, LDL-C,
apo B, and TG.(Pooled results are provided in Table7.)

In patients with Fredrickson Types IIa and IIb
hyperlipoproteinemia pooled from 24controlled trials, the median (25th
and 75th percentile) percent changes from baseline in HDL-C for LIPITOR 10, 20,

respectively. Additionally, analysis of the pooled data demonstrated consistent
and significant decreases in total-C, LDL-C, TG, total-C/HDL-C, and
LDL-C/HDL-C.
In three multicenter, double-blind studies in patients with
hyperlipidemia, LIPITOR was compared to other statins. After randomization,
patients were treated for 16 weeks with either LIPITOR10mgper day or afixed
dose of the comparative agent (Table 8).

Homozygous Familial
Hypercholesterolemia
In a study without a concurrent
control group, 29 patients ages 6yearsto37 years with HoFH received maximum daily
doses of 20 to 80mgof LIPITOR. The mean LDL-C reduction in this study was 18%.
Twenty-five patients with a reduction in LDL-Chad a mean response of 20% (range
of 7% to 53%,median of 24%); the remaining 4patientshad 7% to 24% increases in
LDL-C. Five of the 29 patients had absent LDL-receptor function. Of these, 2
patients also had a portacaval shunt and had no significant reduction in LDL-C.
The remaining 3receptor-negative patients had a mean LDL-C reduction of 22%.
Heterozygous Familial
Hypercholesterolemia In Pediatric Patients
In a double-blind,
placebo-controlled study followed by an open-label phase, 187boys and
post-menarchal girls 10years to17 years of age (mean age 14.1 years) with
heterozygous familial hypercholesterolemia (HeFH)or severe
hypercholesterolemia, were randomized to LIPITOR(n=140) or placebo (n=47) for
26 weeks and then all received LIPITOR for26weeks. Inclusion in the study
required 1) a baseline LDL-C level ≥ 190 mg/dL or 2) a baseline LDL-C
level ≥ 160 mg/dL and positive family history of FH or documented
premature cardiovascular disease in a first or second-degree relative. The mean
baseline LDL-C value was 218.6 mg/dL (range: 138.5-385.0 mg/dL)in the LIPITOR group
compared to230.0 mg/dL (range: 160.0-324.5 mg/dL)in the placebo group. The
dosage of LIPITOR (once daily) was 10mgforthe first 4weeks and uptitrated to 20
mgifthe LDL-C level was > 130mg/dL. The number of LIPITOR-treated patients
who required uptitration to20 mg after Week 4during the double-blind phase
was78(55.7%).
LIPITOR significantly decreased plasma levels of total-C,
LDL-C, triglycerides, and apolipoprotein B during the 26-week double-blind
phase (see Table 11).

double-blind phase.
Atorvastatin was also studied
in a three year open-label, uncontrolled trial that included 163patientswith
HeFH who were 10years to 15 years old (82boys and81girls). Allpatients had a
clinical diagnosis of HeFH confirmed by genetic analysis (if not already
confirmed by family history). Approximately 98% were Caucasian, andlessthan1%
were Black or Asian. Mean LDL-Cat baseline was 232mg/dL. The starting
atorvastatin dosage was 10 mg once daily and doses were adjusted to achieve a
target of < 130 mg/dL LDL-C. The reductions in LDL-C from baseline were
generally consistent across age groups within the trial as well as with
previous clinical studies in both adult and pediatric placebo-controlled
trials.
The long-term efficacy of
LIPITOR therapy in childhood to reduce morbidity and mortality in adulthood has
not been established.

PATIENT INFORMATION
LIPITOR®
(atorvastatin calcium)
Read the Patient Information that comes with LIPITOR before
you start taking it and each time you get a refill. There may be new
information. This leaflet does not take the place of talking with your doctor
about your condition or treatment.
If you have any questions about LIPITOR, ask your doctor
or pharmacist.
What is LIPITOR?
LIPITOR is a prescription medicine that lowers
cholesterol in your blood. It lowers the LDL-C (“bad” cholesterol)
and triglycerides in your blood. It can raise your HDL-C (“good”
cholesterol) as well. LIPITOR is for adults and children over 10 whose
cholesterol does not come down enough with exercise and a low-fat diet alone.
LIPITOR can lower the risk for heart attack, stroke,
certain types of heart surgery, and chest pain in patients who have heart
disease or risk factors for heart disease such as:
age, smoking, high blood pressure, low HDL-C, heart
disease in the family.
LIPITOR can lower the risk for heart attack or stroke in
patients with diabetes and risk factors such as:
eye problems, kidney problems, smoking, or high blood
pressure.
LIPITOR starts to work in about 2 weeks.
What is Cholesterol?
Cholesterol and triglycerides are fats that are made in
your body. They are also found in foods. You need some cholesterol for good
health, but too much is not good for you. Cholesterol and triglycerides can
clog your blood vessels. It is especially important to lower your cholesterol
if you have heart disease, smoke, have diabetes or high blood pressure, are
older, or if family.
Who Should Not Take LIPITOR?
Do not take LIPITOR if you:
are pregnant or think you may be pregnant, or are
planning to become pregnant. LIPITORmay harm your unborn baby. If you get
pregnant, stop taking LIPITOR and call your doctor right away.
are breast feeding. LIPITOR can pass into your breast
milkand may harm your baby.
have liver problems.
are allergic to LIPITOR or any of its ingredients. The
active ingredient is atorvastatin. See the end of this leaflet for a complete
list of ingredients in LIPITOR.
LIPITOR dosinghas not been established in children under
10 years of age.
Before You Start LIPITOR
Tell your doctor if you:
have muscle aches or weakness
drink more than 2 glasses of alcohol daily have diabetes
have a thyroid problem
have kidney problems
Some medicines should not be taken with LIPITOR. Tell
your doctor about all the medicines you take, including prescription and
non-prescription medicines, vitamins, and herbal supplements. LIPITOR and
certain other medicines can interact causing serious side effects. Especially
tell your doctor if you take medicines for:
your immune system
cholesterol
infections
birth control
heart failure
HIV or AIDS
Know all the medicines you take. Keep a list of them with
you to show your doctor and pharmacist.
How Should I Take LIPITOR?
Take LIPITOR exactly as prescribed by your doctor. Do not
change your dose or stop LIPITOR without talking to your doctor. Your doctor
may do blood tests to check your cholesterol levels during your treatment with
LIPITOR. Your dose of LIPITOR may be changed based on these blood test results.
Take LIPITOR each day at any time of day at about the
same time each day. LIPITOR can be taken with or without food.
Don't break LIPITOR tablets before taking.
Your doctor should start you on a low-fat diet before
giving you LIPITOR. Stay on this low-fat diet when you take LIPITOR.
If you miss a dose of LIPITOR, take it as soon as you
remember. Do not take LIPITOR if it has been more than 12 hours since you
missed your last dose. Wait and take the next dose at your regular time.Do not
take 2 doses of LIPITOR at the same time.
If you take too much LIPITOR or overdose, call your
doctor or Poison Control Center right away. Or go to the nearest emergency
room.
What Should I Avoid While Taking LIPITOR?
Talk to your doctor before you start any new medicines.
This includes prescription and nonprescription medicines, vitamins, and herbal
supplements. LIPITOR and certain other medicines can interact causing serious
side effects.
Do not get pregnant. If you get pregnant, stop taking
LIPITOR right away and call your doctor.
What are the Possible Side Effects of LIPITOR?
LIPITOR can cause serious side effects. These side
effects have happened only to a small number of people. Your doctor can monitor
you for them. These side effects usually go away if your dose is lowered or LIPITOR
is stopped. These serious side effects include:
Muscle problems. LIPITOR can cause serious muscle
problems that can lead to kidney problems, including kidney failure. You have a
higher chance for muscle problems if you are taking certain other medicines
with LIPITOR.
Liver problems. Your doctor should do blood tests
to check your liver before you start taking LIPITOR and if you have symptoms of
liver problems while you take LIPITOR. Call your doctor right away if you have
the following symptoms of liver problems:
feel tired or weak
loss of appetite
upper belly pain
dark amber colored urine
yellowing of your skin or the whites of your eyes
Call your doctor right away if you have:
muscle problems like weakness, tenderness, or pain that
happen without a good reason, especially if you also have a fever or feel more
tired than usual. This may be an early sign of a rare muscle problem.
muscle problems that do not go away even after your
doctor has advised you to stop taking LIPITOR. Your doctor may do further tests
to diagnose the cause of your muscle problems.
allergic reactions including swelling of the face, lips,
tongue, and/or throat that may cause difficulty in breathing or swallowing
which may require treatment right away.
nausea and vomiting.
passing brown or dark-colored urine.
you feel more tired than usual
your skin and whites of your eyes get yellow.
stomach pain.
allergic skin reactions.
In clinical studies, patients reported the following
common side effects while taking LIPITOR: diarrhea, upset stomach, muscle and
joint pain, and alterations in some laboratory blood tests.
The following additional side effects have been reported
