Opiates

Codeine

CLINICAL PHARMACOLOGY
The major effects of codeine are on the central nervous system and the bowel. Opioids act as agonists, interacting with stereospecific and saturable binding sites or receptors in the brain and other tissues.

Codeine is readily absorbed from the gastrointestinal tract with the maximum analgesic effect occurring 60 minutes post administration. Codeine retains at least one half its analgesic activity when administered orally.

Dosing (Adult):
Pain: Oral, M, IV, SC: 30 mg (15-60mg) q4-6h prn. (Max 360mg/day).
Cough (non-productive): 10-20mg q4-6h prn (Max: 120 mg/day).

Analgesic:  Oral: 30 mg every 4-6 hours as needed; patients with prior opiate exposure may require higher initial doses. Usual range: 15-120 mg every 4-6 hours as needed

I.M., SubQ: 30 mg every 4-6 hours as needed; patients with prior opiate exposure may require higher initial doses. Usual range: 15-120 mg every 4-6 hours as needed; more frequent dosing may be needed

Antitussive: Oral (for nonproductive cough):
Adults: 10-20 mg/dose every 4-6 hours as needed; maximum: 120 mg/day

-----------------------------------------------------------------
Pain management: Transdermal:
Initial: To convert patients from oral or parenteral opioids to transdermal formulation, a 24-hour analgesic requirement should be calculated (based on prior opiate use). This analgesic requirement should be converted to the equianalgesic oral morphine dose. The initial fentanyl dosage may be approximated from the 24-hour morphine dosage and titrated to minimize adverse effects and provide analgesia. Change patch every 72 hours.    Titration: Short-acting agents may be required until analgesic efficacy is established and/or as supplements for "breakthrough" pain. The amount of supplemental doses should be closely monitored. Appropriate dosage increases may be based on daily supplemental dosage using the ratio of 45 mg/24 hours of oral morphine to a 12.5 mcg/hour increase in fentanyl dosage.    Frequency of adjustment: The dosage should not be titrated more frequently than every 3 days after the initial dose or every 6 days thereafter. Patients should wear a consistent fentanyl dosage through two applications (6 days) before dosage increase based on supplemental opiate dosages can be estimated.   Frequency of application: The majority of patients may be controlled on every 72-hour administration; however, a small number of patients require every 48-hour administration.

Drug UPDATES:  ZOHYDRO ® ER (hydrocodone bitartrate) extended-release capsules, for oral use, CII   [Drug information  /  PDF]   - See link for dosing info.

Mechanism of Action: Hydrocodone is a semi-synthetic opioid agonist with relative selectivity for the mu-opioid (µ) receptor, although it can interact with other opioid receptors at higher doses. Hydrocodone acts as a full agonist, binding to and activating opioid receptors at sites in the peri-aquaductal and peri-ventricular gray matter, the ventro-medial medulla and the spinal cord to produce analgesia. The analgesia, as well as the euphoriant, respiratory depressant and physiologic dependence properties of µ agonist opioids like hydrocodone, result principally from agonist action at the µ receptors.

INDICATIONS AND USAGE:  ZOHYDRO ER is an opioid agonist indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. (1)

Drug UPDATESHYSINGLA™ ER (hydrocodone bitartrate) extended-release tablets, for oral use, CII
[Drug information  /  PDF]  
Dosing:  Click (+) next to Dosage and Administration section (drug info link)

Initial U.S. Approval:  2014

Mechanism of Action: Hydrocodone is a semi-synthetic opioid agonist with relative selectivity for the mu-opioid receptor, although it can interact with other opioid receptors at higher doses. Hydrocodone acts as an agonist binding to and activating opioid receptors in the brain and spinal cord, which are coupled to G-protein complexes and modulate synaptic transmission through adenylate cyclase. The pharmacological effects of hydrocodone including analgesia, euphoria, respiratory depression and physiological dependence are believed to be primarily mediated via µ opioid receptors.

INDICATIONS AND USAGE:
HYSINGLA ER is an opioid agonist indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate.

Limitations of Use:
Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because of the greater risks of overdose and death with extended-release opioid formulations, reserve HYSINGLA ER for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain.
HYSINGLA ER is not indicated as an as-needed (prn) analgesic.

===================
INDIVIDUALIZATION OF DOSAGE
The dosage of opioid analgesics like hydromorphone hydrochloride should be individualized for any given patient, since adverse events can occur at doses that may not provide complete freedom from pain.

Safe and effective administration of opioid analgesics to patients with acute or chronic pain depends upon a comprehensive assessment of the patient. The nature of the pain (severity, frequency, etiology, and pathophysiology) as well as the concurrent medical status of the patient will affect selection of the starting dosage.

In non-opioid-tolerant patients, therapy with hydromorphone is typically initiated at an oral dose of 2-4 mg every four hours, but elderly patients may require lower doses.

In patients receiving opioids, both the dose and duration of analgesia will vary substantially depending on the patient's opioid tolerance. The dose should be selected and adjusted so that at least 3-4 hours of pain relief may be achieved. In patients taking opioid analgesics, the starting dose of DILAUDID should be based on prior opioid usage. This should be done by converting the total daily usage of the previous opioid to an equivalent total daily dosage of oral DILAUDID using an equianalgesic table.

Once the total daily dosage of DILAUDID has been estimated, it should be divided into the desired number of doses. Since there is individual variation in response to different opioid drugs, only 1/2 to 2/3 of the estimated dose of DILAUDID calculated from equivalence tables should be given for the first few doses, then increased as needed according to the patient's response.

Since the pharmacokinetics of hydromorphone are affected in hepatic and renal impairment with a consequent increase in exposure, patients with hepatic and renal impairment should be started on a lower starting dose.

In chronic pain, doses should be administered around-the-clock. A supplemental dose of 5-15% of the total daily usage may be administered every two hours on an "as-needed" basis.

Periodic reassessment after the initial dosing is always required. If pain management is not satisfactory and in the absence of significant opioid-induced adverse events, the hydromorphone dose may be increased gradually. If excessive opioid side effects are observed early in the dosing interval, the hydromorphone dose should be reduced. If this results in breakthrough pain at the end of the dosing interval, the dosing interval may need to be shortened. Dose titration should be guided more by the need for analgesia than the absolute dose of opioid employed.
Acute pain (moderate to severe): Note: These are guidelines and do not represent the maximum doses that may be required in all patients. Doses should be titrated to pain relief/prevention.

Oral: Initial: Opiate-naive: 2-4 mg every 3-4 hours as needed; patients with prior opiate exposure may require higher initial doses; usual dosage range: 2-8 mg every 3-4 hours as needed.

I.V.: Initial: Opiate-naive: 0.2-0.6 mg every 2-3 hours as needed; patients with prior opiate exposure may tolerate higher initial doses.

Note: More frequent dosing may be needed.

Mechanically-ventilated patients (based on 70 kg patient): 0.7-2 mg every 1-2 hours as needed; infusion (based on 70 kg patient): 0.5-1 mg/hour

I.M., SubQ: Note: I.M. use may result in variable absorption and a lag time to peak effect.
Initial: Opiate-naive: 0.8-1 mg every 4-6 hours as needed; patients with prior opiate exposure may require higher initial doses; usual dosage range: 1-2 mg every 3-6 hours as needed
=========================
Chronic pain: Adults: Oral: Note: Patients taking opioids chronically may become tolerant and require doses higher than the usual dosage range to maintain the desired effect. Tolerance can be managed by appropriate dose titration. There is no optimal or maximal dose for hydromorphone in chronic pain. The appropriate dose is one that relieves pain throughout its dosing interval without causing unmanageable side effects.

Controlled release formulation (Hydromorph Contin®, not available in U.S.): 3-30 mg every 12 hours. Note: A patient's hydromorphone requirement should be established using prompt release formulations; conversion to long acting products may be considered when chronic, continuous treatment is required. Higher dosages should be reserved for use only in opioid-tolerant patients.

Extended release formulation (Palladone™): For use only in opioid-tolerant patients requiring extended treatment of pain. Initial Palladone™ dose should be calculated using standard conversion estimates based on previous total daily opioid dose, rounding off to the most appropriate strength available. Doses should be administered once every 24 hours. Discontinue all previous around-the-clock opioids when treatment is initiated. Dose may be adjusted every 2 days as needed.

[REVIEW PACKAGE INSERT ]

Initial U.S. Approval:  2016

Mechanism of Action:
Oxycodone is a full opioid agonist and is relatively selective for the mu receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of oxycodone is analgesia. Like all full opioid agonists, there is no ceiling effect to analgesia for oxycodone. Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression.

The precise mechanism of the analgesic action is unknown. However, specific CNS opioid receptors for endogenous compounds with opioid-like activity have been identified throughout the brain and spinal cord and are thought to play a role in the analgesic effects of this drug. In addition, when oxycodone binds to mu-opioid receptors, it results in positive subjective effects, such as drug liking, euphoria, and high.

INDICATIONS AND USAGE:
XTAMPZA ER is an opioid agonist product indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. (1)

Limitations of Use
Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because of the greater risks of overdose and death with extended-release opioid formulations, reserve XTAMPZA ER for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain. (1)
XTAMPZA ER is not indicated as an as-needed (prn) analgesic. (1)

DOSAGE AND ADMINISTRATION:

  • XTAMPZA ER at a total daily dose greater than 72 mg (equivalent to 80 mg oxycodone hydrochloride [HCl]) or a single dose greater than 36 mg (equivalent to 40 mg oxycodone HCl) is only for use in patients in whom tolerance to an opioid of comparable potency has been established. (2.1)
  • Patients considered opioid tolerant are those receiving, for one week or longer, at least 60 mg oral morphine per day, 25 mcg transdermal fentanyl per hour, 30 mg oral oxycodone HCl per day, 8 mg oral hydromorphone per day, 25 mg oral oxymorphone per day, 60 mg oral hydrocodone per day, or an equianalgesic dose of another opioid. (2.1)
  • Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (2.1)
  • For opioid-naïve and opioid non-tolerant patients, initiate with 9 mg (equivalent to 10 mg oxycodone HCl) capsules orally every 12 hours with food. (2.2)
  • The daily dose of XTAMPZA ER must be limited to a maximum of 288 mg per day (equivalent to 320 mg oxycodone HCl per day) (2.1)
  • Hepatic impairment: Initiate therapy at 1/3 to 1/2 the usual dosage and titrate carefully. Monitor carefully. Use alternate analgesia for patients requiring less than 9 mg. (2.3, 8.6)
  • Do not abruptly discontinue XTAMPZA ER in a physically dependent patient. (2.5)
  • Instruct patients to take XTAMPZA ER capsules with food in order to ensure consistent plasma levels are achieved. For patients who have difficulty swallowing, XTAMPZA ER can also be taken by sprinkling the capsule contents on soft foods or into a cup and then administering directly into the mouth, or through a gastrostomy or nasogastric feeding tube.

Tramadol (Ultram®)

Pharmacodynamics
ULTRAM® contains tramadol, a centrally acting synthetic opioid analgesic. Although its mode of action is not completely understood, from animal tests, at least two complementary mechanisms appear applicable: binding of parent and M1 metabolite to µ-opioid receptors and weak inhibition of reuptake of norepinephrine and serotonin.

Opioid activity is due to both low affinity binding of the parent compound and higher affinity binding of the O-demethylated metabolite M1 to µ-opioid receptors. In animal models, M1 is up to 6 times more potent than tramadol in producing analgesia and 200 times more potent in µ-opioid binding. Tramadol-induced analgesia is only partially antagonized by the opiate antagonist naloxone in several animal tests. The relative contribution of both tramadol and M1 to human analgesia is dependent upon the plasma concentrations of each compound.

Tramadol has been shown to inhibit reuptake of norepinephrine and serotonin in vitro, as have some other opioid analgesics. These mechanisms may contribute independently to the overall analgesic profile of ULTRAM®. Analgesia in humans begins approximately within one hour after administration and reaches a peak in approximately two to three hours.

Dosing (Adults):
Oral: Moderate to severe chronic pain: 50-100 mg every 4-6 hours, not to exceed 400 mg/day

For patients not requiring rapid onset of effect, tolerability may be improved by starting dose at 25 mg/day and titrating dose by 25 mg every 3 days, until reaching 25 mg 4 times/day. Dose may then be increased by 50 mg every 3 days as tolerated, to reach dose of 50 mg 4 times/day.

Elderly: >75 years: 50-100 mg every 4-6 hours (not to exceed 300 mg/day); see dosing adjustments for renal and hepatic impairment

Dosing adjustment in renal impairment: Clcr<30 mL/minute: Administer 50-100 mg dose every 12 hours (maximum: 200 mg/day)

Dosing adjustment in hepatic impairment: Cirrhosis: Recommended dose: 50 mg every 12 hours

Agonist-Antagonists

Buprenorphine (Buprenex®)

Dosing (Adults):
Long-term use is not recommended
Note: These are guidelines and do not represent the maximum doses that may be required in all patients. Doses should be titrated to pain relief/prevention. In high-risk patients (eg, elderly, debilitated, presence of respiratory disease) and/or concurrent CNS depressant use, reduce dose by one-half. Buprenorphine has an analgesic ceiling.

Acute pain (moderate to severe):

I.M.: Initial: Opiate-naive: 0.3 mg every 6-8 hours as needed; initial dose (up to 0.3 mg) may be repeated once in 30-60 minutes after the initial dose if needed; usual dosage range: 0.15-0.6 mg every 4-8 hours as needed

Slow I.V.: Initial: Opiate-naive: 0.3 mg every 6-8 hours as needed; initial dose (up to 0.3 mg) may be repeated once in 30-60 minutes after the initial dose if needed

Elderly: 0.15 mg every 6 hours; elderly patients are more likely to suffer from confusion and drowsiness compared to younger patients

Sublingual: Adults: Opioid dependence:
Induction: Range: 12-16 mg/day (doses during an induction study used 8 mg on day 1, followed by 16 mg on day 2; induction continued over 3-4 days). Treatment should begin at least 4 hours after last use of heroin or short-acting opioid, preferably when first signs of withdrawal appear. Titrating dose to clinical effectiveness should be done as rapidly as possible to prevent undue withdrawal symptoms and patient drop-out during the induction period.

Maintenance: Target dose: 16 mg/day; range: 4-24 mg/day; patients should be switched to the buprenorphine/naloxone combination product for maintenance and unsupervised therapy

Administration
I.V.: Administer slowly, over at least 2 minutes.

WARNING: IMPLANT MIGRATION, PROTRUSION, EXPULSION, and NERVE DAMAGE ASSOCIATED WITH INSERTION and REMOVAL

Risk Associated with Insertion and Removal

Insertion and removal of PROBUPHINE are associated with the risk of implant migration, protrusion, and expulsion resulting from the procedure. Rare but serious complications including nerve damage and migration resulting in embolism and death may result from improper insertion of drug implants inserted in the upper arm. Additional complications may include local migration, protrusion and expulsion.

Incomplete insertions or infections may lead to protrusion or expulsion. [see Warnings and Precautions (5.1)].

Because of the risks associated with insertion and removal, PROBUPHINE is available only through a restricted program called the PROBUPHINE REMS Program. All Healthcare Providers must successfully complete a live training program on the insertion and removal procedures and become certified, prior to performing insertions or prescribing PROBUPHINE implants. Patients must be monitored to ensure that PROBUPHINE is removed by a healthcare provider certified to perform insertions. [see Warnings and Precautions (5.2)].

Initial U.S. Approval:  2016

Mechanism of Action:
PROBUPHINE implants contain buprenorphine HCl. Buprenorphine is a partial agonist at the mu- opioid receptor and an antagonist at the kappa-opioid receptor.

INDICATIONS AND USAGE:
PROBUPHINE contains buprenorphine, a partial opioid agonist. PROBUPHINE is indicated for the maintenance treatment of opioid dependence in patients who have achieved and sustained prolonged clinical stability on low-to-moderate doses of a transmucosal buprenorphine- containing product (i.e., doses of no more than 8 mg per day of Subutex or Suboxone sublingual tablet or generic equivalent). (1)

PROBUPHINE should be used as part of a complete treatment program to include counseling and psychosocial support. (1)

PROBUPHINE is not appropriate for new entrants to treatment and patients who have not achieved and sustained prolonged clinical stability, while being maintained on buprenorphine 8 mg per day or less of a Subutex or Suboxone sublingual tablet or generic equivalent. (1)

DOSAGE AND ADMINISTRATION:
Prescription use of this product is limited under the Drug Addiction Treatment Act. (2.1)

Four PROBUPHINE implants are inserted subdermally in the upper arm for 6 months of treatment and are removed by the end of the sixth month. (2.2)

PROBUPHINE implants should not be used for additional treatment cycles after one insertion in each upper arm. (2.2)

PROBUPHINE implants must be inserted and removed by trained Healthcare Providers only. (2.3)

PROBUPHINE implants should be administered in patients who have achieved and sustained prolonged clinical stability on transmucosal buprenorphine. (2.4)

Examine the insertion site one week following insertion of PROBUPHINE implants for signs of infection or other problems. (2.5)

HOW SUPPLIED:
DOSAGE FORMS AND STRENGTHS
Each PROBUPHINE implant is an ethylene vinyl acetate (EVA) implant, 26 mm in length and 2.5 mm in diameter, containing 74.2 mg of buprenorphine (equivalent to 80 mg of buprenorphine hydrochloride).

Antagonists

Nalmefene (Revex)

Dosing (Adults):
Reversal of postoperative opioid depression: Blue labeled product (100 mcg/mL): Titrate to reverse the undesired effects of opioids; initial dose for nonopioid dependent patients: 0.25 mcg/kg followed by 0.25 mcg/kg incremental doses at 2- to 5-minute intervals; after a total dose >1 mcg/kg, further therapeutic response is unlikely

Management of known/suspected opioid overdose: Green labeled product (1000 mcg/mL): Initial dose: 0.5 mg/70 kg; may repeat with 1 mg/70 kg in 2-5 minutes; further increase beyond a total dose of 1.5 mg/70 kg will not likely result in improved response and may result in cardiovascular stress and precipitated withdrawal syndrome. (If opioid dependency is suspected, administer a challenge dose of 0.1 mg/70 kg; if no withdrawal symptoms are observed in 2 minutes, the recommended doses can be administered.)

Note: If recurrence of respiratory depression is noted, dose may again be titrated to clinical effect using incremental doses.

Note: If I.V. access is lost or not readily obtainable, a single SubQ or I.M. dose of 1 mg may be effective in 5-15 minutes.

Dosing adjustment in renal or hepatic impairment: Not necessary with single uses, however, slow administration (over 60 seconds) of incremental doses is recommended to minimize hypertension and dizziness

SUPPLIED:
Injection, solution: 100 mcg/mL (1 mL); 1000 mcg/mL (2 mL)

Naltrexone (ReVia® )

INDICATIONS:
Treatment of ethanol dependence; blockade of the effects of exogenously administered opioids

Pharmacodynamic Actions: REVIA is a pure opioid antagonist. It markedly attenuates or completely blocks, reversibly, the subjective effects of intravenously administered opioids.

When co-administered with morphine, on a chronic basis, REVIA blocks the physical dependence to morphine, heroin and other opioids.

REVIA has few, if any, intrinsic actions besides its opioid blocking properties. However, it does produce some pupillary constriction, by an unknown mechanism.

The administration of REVIA is not associated with the development of tolerance or dependence. In subjects physically dependent on opioids, REVIA will precipitate withdrawal symptomatology.

Dosing (Adults):
Do not give until patient is opioid-free for 7-10 days as determined by urine analysis
Adults: Oral: 25 mg; if no withdrawal signs within 1 hour give another 25 mg; maintenance regimen is flexible, variable and individualized (50 mg/day to 100-150 mg 3 times/week for 12 weeks); up to 800 mg/day has been tolerated in adults without an adverse effect

Dosing cautions in renal/hepatic impairment: Caution in patients with renal and hepatic impairment. An increase in naltrexone AUC of approximately five- and 10-fold in patients with compensated or decompensated liver cirrhosis respectively, compared with normal liver function has been reported.

Administration
If there is any question of occult opioid dependence, perform a naloxone challenge test; do not attempt treatment until naloxone challenge is negative.
Naltrexone is administered orally; to minimize adverse gastrointestinal effects, administer with food or antacids or after meals; advise patient not to self-administer opiates while receiving naltrexone therapy

DOSAGE AND ADMINISTRATION
IF THERE IS ANY QUESTION OF OCCULT OPIOID DEPENDENCE, PERFORM A NALOXONE CHALLENGE TEST AND DO NOT INITIATE REVIA THERAPY UNTIL THE NALOXONE CHALLENGE IS NEGATIVE.

Treatment of Alcoholism:
A dose of 50 mg once daily is recommended for most patients (see Individualization of Dosage ). The placebo-controlled studies that demonstrated the efficacy of REVIA as an adjunctive treatment of alcoholism used a dose regimen of REVIA 50 mg once daily for up to 12 weeks. Other dose regimens or durations of therapy were not evaluated in these trials.

A patient is a candidate for treatment with REVIA if:
The patient is willing to take a medicine to help with alcohol dependence.
The patient is opioid free for 7-10 days.
The patient does not have severe or active liver or kidney problems (Typical guidelines suggest liver function tests no greater than 3 times the upper limits of normal, and bilirubin normal.)
The patient is not allergic to REVIA , and no other contraindications are present.

REVIA should be considered as only one of many factors determining the success of treatment of alcoholism. Factors associated with a good outcome in the clinical trials with REVIA were the type, intensity, and duration of treatment; appropriate management of comorbid conditions; use of community-based support groups; and good medication compliance. To achieve the best possible treatment outcome, appropriate compliance-enhancing techniques should be implemented for all components of the treatment program, especially medication compliance.

Treatment of Opioid Dependence:
Initiate treatment with REVIA using the following guidelines:
1.) Treatment should not be attempted unless the patient has remained opioid-free for at least 7-10 days. Self-reporting of abstinence from opioids in opioid addicts should be verified by analysis of the patient's urine for absence of opioids. The patient should not be manifesting withdrawal signs or reporting withdrawal symptoms.
2.) If there is any question of occult opioid dependence, perform a naloxone challenge test. If signs of opioid withdrawal are still observed following naloxone challenge, treatment with REVIA should not be attempted. The naloxone challenge can be repeated in 24 hours.
3.) Treatment should be initiated carefully, with an initial dose of 25 mg of REVIA. If no withdrawal signs occur, the patient may be started on 50 mg a day thereafter.

Naloxone Challenge Test: The naloxone challenge test should not be performed in a patient showing clinical signs or symptoms of opioid withdrawal, or in a patient whose urine contains opioids. The naloxone challenge test may be administered by either the intravenous or subcutaneous routes.

Intravenous:
Inject 0.2 mg naloxone.
Observe for 30 seconds for signs or symptoms of withdrawal.
If no evidence of withdrawal, inject 0.6 mg of naloxone.
Observe for an additional 20 minutes.

Subcutaneous:
Administer 0.8 mg naloxone.

Observe for 20 minutes for signs or symptoms of withdrawal.

Note: Individual patients, especially those with opioid dependence, may respond to lower doses of naloxone. In some cases, 0.1 mg IV naloxone has produced a diagnostic response.

Interpretation of the Challenge: Monitor vital signs and observe the patient for signs and symptoms of opioid withdrawal. These may include, but are not limited to: nausea, vomiting, dysphoria, yawning, sweating, tearing, rhinorrhea, stuffy nose, craving for opioids, poor appetite, abdominal cramps, sense of fear, skin erythema, disrupted sleep patterns, fidgeting, uneasiness, poor ability to focus, mental lapses, muscle aches or cramps, pupillary dilation, piloerection, fever, changes in blood pressure, pulse or temperature, anxiety, depression, irritability, back ache, bone or joint pains, tremors, sensations of skin crawling or fasciculations. If signs or symptoms of withdrawal appear, the test is positive and no additional naloxone should be administered.

Warning: If the test is positive, do NOT initiate REVIA therapy. Repeat the challenge in 24 hours. If the test is negative, REVIA therapy may be started if no other contraindictions are present. If there is any doubt about the result of the test, hold REVIA and repeat the challenge in 24 hours.

Alternative Dosing Schedules:
Once the patient has been started on REVIA, 50 mg every 24 hours will produce adequate clinical blockade of the actions of parenterally administered opioids (i.e., this dose will block the effects of a 25 mg intravenous heroin challenge). A flexible approach to a dosing regimen may need to be employed in cases of supervised administration. Thus, patients may receive 50 mg of REVIA every weekday with a 100 mg dose on Saturday, 100 mg every other day, or 150 mg every third day. The degree of blockade produced by REVIA may be reduced by these extended dosing intervals.

There may be a higher risk of hepatocellular injury with single doses above 50 mg, and use of higher doses and extended dosing intervals should balance the possible risks against the probable benefits.

Naloxone (Narcan®)

CLINICAL PHARMACOLOGY
Complete or Partial Reversal of Opioid Depression
NARCAN prevents or reverses the effects of opioids including respiratory depression, sedation and hypotension. Also, NARCAN can reverse the psychotomimetic and dysphoric effects of agonist-antagonists such as pentazocine.

NARCAN is an essentially pure opioid antagonist, i.e., it does not possess the "agonistic" or morphine-like properties characteristic of other opioid antagonists. When administered in usual doses and in the absence of opioids or agonistic effects of other opioid antagonists, it exhibits essentially no pharmacologic activity.

NARCAN has not been shown to produce tolerance or cause physical or psychological dependence. In the presence of physical dependence on opioids, NARCAN will produce withdrawal symptoms. However, in the presence of opioid dependence, opiate withdrawal symptoms may appear within minutes of NARCAN administration and subside in about 2 hours. The severity and duration of the withdrawal syndrome are related to the dose of NARCAN and to the degree and type of opioid dependence.

While the mechanism of action of NARCAN is not fully understood, in vitro evidence suggests that NARCAN antagonizes opioid effects by competing for the µ, κ and σ opiate receptor sites in the CNS, with the greatest affinity for the µ receptor.

Dosing (Adults):
I.M., I.V. (preferred), intratracheal, SubQ:

Narcotic overdose: Adults: I.V.: 0.4-2 mg every 2-3 minutes as needed; may need to repeat doses every 20-60 minutes, if no response is observed after 10 mg, question the diagnosis. Note: Use 0.1-0.2 mg increments in patients who are opioid dependent and in postoperative patients to avoid large cardiovascular changes.

Adults: Continuous infusion: I.V.: If continuous infusion is required, calculate dosage/hour based on effective intermittent dose used and duration of adequate response seen, titrate dose 0.04-0.16 mg/kg/hour for 2-5 days in children, adult dose typically 0.25-6.25 mg/hour (short-term infusions as high as 2.4 mg/kg/hour have been tolerated in adults during treatment for septic shock); alternatively, continuous infusion utilizes 2 /3 of the initial naloxone bolus on an hourly basis; add 10 times this dose to each liter of D5W and infuse at a rate of 100 mL/hour; 1 /2 of the initial bolus dose should be readministered 15 minutes after initiation of the continuous infusion to prevent a drop in naloxone levels; increase infusion rate as needed to assure adequate ventilation

Ziconotide (Prialt ®)

CLINICAL PHARMACOLOGY
Mechanism of Action
Ziconotide binds to N-type calcium channels located on the primary nociceptive (A-δ and C) afferent nerves in the superficial layers (Rexed laminae I and II) of the dorsal horn in the spinal cord. Although the mechanism of action of ziconotide has not been established in humans, results in animals suggest that its binding blocks N-type calcium channels, which leads to a blockade of excitatory neurotransmitter release from the primary afferent nerve terminals and antinociception.

Dosage (adults):
I.T.:  Chronic pain: Initial dose: 2.4 mcg/day (0.1 mcg/hour)

Dose may be titrated by </= 2.4 mcg/day (0.1 mcg/hour) at intervals >/= 2-3 times/week to a maximum dose of 19.2 mcg/day (0.8 mcg/hour) by day 21; average dose at day 21: 6.9 mcg/day (0.29 mcg/hour). A faster titration should be used only if the urgent need for analgesia outweighs the possible risk to patient safety.

Administration
Not for I.V. administration. For I.T. administration only using a Medtronic SynchroMed® EL, SynchroMed® II Infusion System or Simms Deltec Cadd Micro® External Microinfusion Device and Catheter.
Medtronic SynchroMed® EL or SynchroMed® II Infusion Systems:
