OsmoPrep®
(sodium phosphate monobasic monohydrate, USP and sodium phosphate dibasic
anhydrous, USP)
WARNING
There have been rare, but serious reports of acute phosphate nephropathy in patients who received oral sodium phosphate products for colon cleansing prior to colonoscopy. Some cases have resulted in permanent impairment of renal function and some patients required long-term dialysis. While some cases have occurred in patients without identifiable risk factors, patients at increased risk of acute phosphate nephropathy may include those with increased age, hypovolemia, increased bowel transit time (such as bowel obstruction), active colitis, or baseline kidney disease, and those using medicines that affect renal perfusion or function (such as diuretics, angiotensin converting enzyme [ACE] inhibitors, angiotensin receptor blockers [ARBs], and possibly nonsteroidal anti-inflammatory drugs [NSAIDs]). [See WARNINGS AND PRECAUTIONS]
It is important to use the dose and dosing regimen as recommended (pm/am split dose). [see DOSAGE AND ADMINISTRATION]

The following serious or otherwise important adverse reactions for bowel preparations are described elsewhere in the labeling:
Because clinical trials are conducted under widely varying conditions, 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 practice.
The safety of OsmoPrep was evaluated in two randomized, investigator-blinded, active controlled trials in 931 adult patients undergoing elective colonoscopy. The mean age of the study population was 60 years (range 20 to 89 years), 88% of patients were Caucasian and 55% were female [see Clinical Studies].
Table 1 shows the most common adverse reactions reported in greater than 3% of patients by treatment group in Study 1 [see Clinical Studies]. Since diarrhea was considered as a part of the efficacy of OsmoPrep, diarrhea was not defined as an adverse event in this clinical trial.

A total of, 96%, 96%, and 93% of patients who took 60 grams of oral sodium phosphate, 60 grams of OsmoPrep, and 48 grams of OsmoPrep, respectively, developed hyperphosphatemia (defined as phosphate level > 5.1 mg/dL) on the day of the colonoscopy. In this study, patients who took 60 grams of oral sodium phosphate, 60 grams of OsmoPrep, and 48 grams of OsmoPrep had baseline mean phosphate levels of 3.5, 3.5, and 3.6 mg/dL and subsequently developed mean phosphate levels of 7.6, 7.9, and 7.1 mg/dL, respectively, on the day of the colonoscopy.
A total of 20%, 22%, and 18% of patients who took 60 grams of oral sodium phosphate, 60 grams of OsmoPrep, and 48 grams of OsmoPrep, respectively, developed hypokalemia (defined as a potassium level < 3.4 mEq/L) on the day of the colonoscopy. In this study, patients who took 60 grams of oral sodium phosphate, 60 grams of OsmoPrep, and 48 grams of OsmoPrep all had baseline potassium levels of about 4.3 mEq/L and then developed a mean potassium level of 3.7 mEq/L on the day of the colonoscopy.
Several patients on all three sodium phosphate regimens developed hypocalcemia and hypernatremia that did not require treatment.
The OsmoPrep 60-gram dosage regimen was associated with an increased risk of adverse reactions compared to the 48gram dosage regimen and a similar overall response rate [see Clinical Studies]. Therefore, the OsmoPrep 60-gram dosage is not a recommended regimen [see DOSAGE AND ADMINISTRATION].
The following adverse reactions have been identified during post-approval use of OsmoPrep. Because these reactions are reported voluntarily from a population of unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Hypersensitivity reactions: anaphylaxis, angioedema (swelling of the lips, tongue and face), rash, pruritus, urticaria, throat tightness, bronchospasm, dyspnea, pharyngeal edema, dysphagia, and paresthesia.
Cardiovascular: Arrhythmias
Nervous system: Seizures
Renal: Renal impairment, increased blood urea nitrogen (BUN), increased creatinine, acute renal failure, acute phosphate nephropathy, nephrocalcinosis, and renal tubular necrosis.
Use caution when prescribing OsmoPrep for patients with conditions, or who are using medications, that increase the risk for fluid and electrolyte disturbances or may increase the risk of renal impairment, seizures, arrhythmias, or prolonged QT in the setting of fluid and electrolyte abnormalities. Consider additional patient evaluations as appropriate in patients taking these concomitant medications [see WARNINGS AND PRECAUTIONS].
OsmoPrep can reduce the absorption of other coadministered oral medications. Administer oral medications at least 1 hour before or 1 hour after starting each OsmoPrep dose [see DOSAGE AND ADMINISTRATION].
Administration of additional sodium phosphate-based purgative or enema products with OsmoPrep may increase the risk of acute phosphate nephropathy. Avoid concomitant use [see WARNINGS AND PRECAUTIONS].
Included as part of the PRECAUTIONS section.
There have been rare, but serious, reports of renal failure, acute phosphate nephropathy, and nephrocalcinosis in patients who received oral sodium phosphate products, including OsmoPrep, for colon cleansing prior to colonoscopy. These cases often resulted in permanent impairment of renal function and several patients required long-term dialysis. The time to onset is typically within days; however, in some cases, the diagnosis of these events has been delayed up to several months after the ingestion of these products. Patients at increased risk of acute phosphate nephropathy may include patients with the following: hypovolemia, baseline kidney disease, increased age, and patients using medicines that affect renal perfusion or function [such as diuretics, angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers, and possibly nonsteroidal anti-inflammatory drugs (NSAIDs) [see DRUG INTERACTIONS].
Bowel preparations, including OsmoPrep can cause fluid and electrolyte disturbances, which can lead to serious adverse reactions including cardiac arrhythmias, seizures and renal impairment [see ADVERSE REACTIONS].
There have been rare reports of serious arrhythmias associated with the use of ionic osmotic laxative products for bowel preparation. QT prolongation with sodium phosphate tablets has been associated with electrolyte imbalances, such as hypokalemia and hypocalcemia.
Use caution when prescribing OsmoPrep for patients at increased risk of arrhythmias (e.g., patients with a history of prolonged QT, uncontrolled arrhythmias, recent myocardial infarction, unstable angina, congestive heart failure, or cardiomyopathy) and those taking medications known to prolong the QT interval, since serious complications may occur. Consider pre-dose and post-colonoscopy ECGs s in patients at increased risk of serious cardiac arrhythmias.
There have been rare reports of generalized tonic-clonic seizures and/or loss of consciousness associated with use of sodium phosphate osmotic laxative products, such as OsmoPrep, in patients with no prior history of seizures. The seizure cases were associated with electrolyte abnormalities (e.g., hyponatremia, hypokalemia, hypocalcemia, and hypomagnesemia) and low serum osmolality. The neurologic abnormalities resolved with correction of fluid and electrolyte abnormalities.
Use OsmoPrep with caution in patients with a history of seizures and in patients at higher risk of seizure, such as patients taking medications that lower the seizure threshold (such as tricyclic antidepressants), patients withdrawing from alcohol or benzodiazepines, or patients with known or suspected hyponatremia [see DRUG INTERACTIONS].
If gastrointestinal obstruction or perforation is suspected, perform appropriate diagnostic studies to rule out these conditions before administering OsmoPrep [see CONTRAINDICATIONS].
Use with caution in patients with severe active ulcerative colitis.
Osmotic laxatives, including OsmoPrep, may induce colonic mucosal aphthous ulcerations. In the OsmoPrep clinical program, aphthous ulcers were observed in 3% of patients who took the recommended OsmoPrep dosing regimen. Consider the potential for mucosal ulcerations resulting from bowel preparation when interpreting colonoscopic finding should in patients with known or suspected inflammatory bowel disease.
Use OsmoPrep with caution in patients experiencing an acute exacerbation of chronic inflammatory bowel disease as published data suggest that sodium phosphate absorption may be enhanced in such patients.
Patients with impaired gag reflex or other swallowing abnormalities are at risk for regurgitation or aspiration of OsmoPrep. Observed these patients during administration of OsmoPrep.
OsmoPrep may cause serious hypersensitivity reactions including anaphylaxis, angioedema, rash, urticaria, and throat tightness [see ADVERSE REACTIONS]. Inform patients of the signs and symptoms of anaphylaxis and instruct them to seek immediate medical care should signs and symptoms occur.
Advise the patient to read the FDA-approved patient labeling (Medication Guide).
No Information provided
There are no available data on sodium phosphate use in pregnant women to inform a drug-associated risk for adverse developmental outcomes.
Animal reproduction studies have not been conducted with sodium phosphate.
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
There are no data available to assess the presence of sodium phosphate in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production.
The lack of clinical data during lactation precludes a clear determination of the risk of OsmoPrep to a child during lactation; therefore, the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for OsmoPrep and any potential adverse effects on the breastfed child from OsmoPrep or from the underlying maternal condition.
Safety and effectiveness in pediatric patients have not been established.
Of the 599 patients in clinical trials receiving at least 48 grams of OsmoPrep, 134 (22%) were 65 years of age or older, while 27 (5%) were 75 years of age or older.
No overall differences in safety or effectiveness were observed between geriatric patients and younger patients. However, the mean phosphate levels in geriatric patients were greater than the phosphate levels in younger patients after OsmoPrep administration. The mean colonoscopy-day phosphate levels in patients 18-64, 65-74, and ≥ 75 years old who received the recommended OsmoPrep dosage regimen in Study 1were 7.0, 7.3, and 8.0 mg/dL, respectively. After OsmoPrep administration, the mean phosphate levels in patients 18-64, 65-74, and ≥ 75 years old were 7.4, 7.9, and 8.0 mg/dL, respectively. Greater sensitivity of some older individuals cannot be ruled out; therefore, use OsmoPrep with caution in geriatric patients. Advise geriatric patients to adequately hydrate before, during, and after the use of OsmoPrep.
Sodium phosphate is known to be substantially excreted by the kidney, and the risk of adverse reactions with sodium phosphate may be greater in patients with impaired renal function. Since geriatric patients are more likely to have impaired renal function, consider performing baseline and post-colonoscopy labs (phosphate, calcium, potassium, sodium, creatinine, and BUN) in these patients [see WARNINGS AND PRECAUTIONS].
Sodium phosphate is substantially excreted by the kidney. Use OsmoPrep with caution in patients with severe renal impairment (creatinine clearance less than 30 mL/min) or patients taking concomitant medications that may affect renal function. These patients may be at risk for renal injury. Advise these patients of the importance of adequate hydration before, during and after the use of OsmoPrep, and consider performing baseline and post-colonoscopy labs (phosphate, calcium, potassium, sodium, creatinine, and BUN) in these patients [see WARNINGS AND PRECAUTIONS, DRUG INTERACTIONS].
Overdosage of OsmoPrep may lead to severe electrolyte disturbances, including hyperphosphatemia, hypocalcemia, hypernatremia, or hypokalemia, as well as dehydration and hypovolemia, with attendant signs and symptoms of these disturbances. Certain severe electrolyte disturbances resulting from overdose may lead to cardiac arrhythmias, seizure, renal failure, and death [see WARNINGS AND PRECAUTIONS]. Monitor for fluid and electrolyte disturbances and treated symptomatically.
OsmoPrep is contraindicated in the following conditions:
The primary mode of action is the osmotic effect of sodium, which induces a laxative effect. The physiological consequence is increased water retention in the lumen of the colon, resulting in loose stools.
Administration of the recommended OsmoPrep dosage regimen has a purgative effect for approximately 1 to 3 hours.
Pharmacokinetic studies with OsmoPrep have not been conducted. However, the following pharmacokinetic study was conducted with another oral tablet formulation of sodium phosphate which contain the same active ingredients as OsmoPrep at a dose that is 25% greater than the OsmoPrep dose.
An open-label pharmacokinetic study of oral sodium phosphate in healthy subjects was performed to determine the concentration-time profile of serum inorganic phosphorus levels after oral sodium phosphate administration. All subjects received the approved dosing regimen for colon cleansing of 60 grams of sodium phosphate with a total liquid volume of 3.6 quarts. A 30-gram dose (20 tablets given as 3 tablets every 15 minutes with 8 ounces of clear liquids) was given beginning at 6 PM in the evening. The 30-gram dose (20 tablets given as 3 tablets every 15 minutes with 8 ounces of clear liquids) was repeated the following morning beginning at 6 AM.
Twenty-three healthy subjects (mean age 57 years old; 57% male and 43% female; and 65% Hispanic, 30% Caucasian, and 4% African-American) participated in this pharmacokinetic study. The serum phosphorus level rose from a mean (± standard deviation) baseline of 4.0 (± 0.7) mg/dL to 7.7 (± 1.6 mg/dL), at a median of 3 hours after the administration of the first 30-gram dose of sodium phosphate tablets (see Figure 1). The serum phosphorus level rose to a mean of 8.4 (± 1.9) mg/dL, at a median of 4 hours after the administration of the second 30-gram dose of sodium phosphate tablets. The serum phosphorus level remained above baseline for a median of 24 hours after the administration of the initial dose of sodium phosphate tablets (range 16 to 48 hours).

The upper (4.5 mg/dL) and lower (2.6 mg/dL) reference limits for serum phosphate are represented by solid bars.
No difference in serum phosphate AUC values were observed in the single pharmacokinetic study conducted with sodium phosphate tablets in 13 male and 10 female healthy subjects.
In a single pharmacokinetic study of sodium phosphate tablets, which included 6 elderly subjects, plasma half-life increased two-fold in subjects > 70 years of age compared to subjects < 50 years of age (3 subjects and 5 subjects, respectively) [see Use In Specific Populations].
The effect of renal impairment on the pharmacokinetics of OsmoPrep has not been studied. The inorganic form of phosphate in the circulating plasma is excreted almost entirely by the kidneys [see WARNINGS AND PRECAUTIONS, Use In Specific Populations].
The colon cleansing efficacy and safety of OsmoPrep was evaluated in a randomized, investigator-blinded, actively controlled, multicenter, U.S. trial in patients scheduled to have an elective colonoscopy (Study 1).
In Study 1, patients were randomized into one of the following three sodium phosphate treatment groups:
Patients were instructed to eat a light breakfast before noon on the day prior to the colonoscopy and then were told to drink only clear liquids after noon on the day prior to the colonoscopy.
The primary efficacy endpoint was the overall colon cleansing response rate in the 4-point Colonic Contents Scale. Response was defined as a rating of “excellent” or “good” on the 4-point scale as determined by the blinded colonoscopist. This trial was designed to assess the non-inferiority of the two OsmoPrep groups compared to the active control group.
The efficacy analysis included 704 adult patients who had an elective colonoscopy. Patients ranged in age from 21 to 89 years old (mean age 56 years old) with 55% female and 45% male patients. Race was distributed as follows: 87% Caucasian, 10% African American, and 3% other race. The OsmoPrep 60-gram and 48-gram treatment groups demonstrated non-inferiority compared to the active control. See Table 2 for the results.

| 1Colon cleansing efficacy was based on
response rate to treatment. A patient was considered to be a responder if
overall colon cleansing was rated as “excellent” or “good” on a 4-point scale
based on the amount of retained “colonic contents”. Excellent was defined as
>90% of mucosa seen, mostly liquid stool, minimal suctioning needed for
adequate visualization. Good was defined as >90% of mucosa seen, mostly
liquid stool, significant suctioning needed for adequate visualization. Fair
was defined as >90% of mucosa seen, mixture of liquid and semisolid stool,
could be suctioned and/or washed. Inadequate was defined as <90% of mucosa
seen, mixture of semisolid and solid stool which could not be suctioned or
washed. 2On the day of the colonoscopy, study medication was taken 3 to 5 hours before the start of the colonoscopy. |
|||||||
The OsmoPrep 60-gram dosage regimen had a similar overall response rate as the 48-gram dosage regimen and was associated with an increased risk of adverse reactions [see ADVERSE REACTIONS]. Therefore, the OsmoPrep 60-gram dosage is not a recommended regimen [see DOSAGE AND ADMINISTRATION].
