First, naltrexone can reduce craving, which is the urge or desire to drink.Because Naltrexone blocks the effects.

Naltrexone is an opioid antagonist with highest affinity for the mu opioid receptor. Naltrexone has little or no opioid agonist activity.
VIVITROL is not aversive therapy and does not cause a disulfiram-like reaction either as a result of opiate use or ethanol ingestion. Pharmacokinetics Absorption VIVITROL is an extended-release, microsphere formulation of naltrexone designed to be administered by intramuscular (IM) gluteal injection every 4 weeks or.Most commonly, these are "non-preferred" brand drugs. 4 This drug is available at a higher level co-pay. Most commonly, these are "non-preferred" brand drugs or specialty prescription products. 5 This drug is available at a higher level co-pay.
Opioid Dependence The efficacy of VIVITROL in the treatment of opioid dependence was evaluated in a 24-week, placebo-controlled, multi-center, double-blind, randomized trial of opioid-dependent (DSM-IV) outpatients, who were completing or had recently completed detoxification.12.1 Mechanism of action Naltrexone is an opioid antagonist with highest affinity for the mu opioid receptor. Naltrexone has little or no opioid agonist activity.
Beginning approximately 14 days after dosing, concentrations slowly decline, with measurable levels for greater than 1 month. Maximum plasma concentration (Cmax) and area under the curve (AUC) for naltrexone and 6naltrexol (the major metabolite) following VIVITROL administration are dose proportional.Production of the primary metabolite, 6-naltrexol, is mediated by dihydrodiol dehydrogenase, a cytosolic family of enzymes. The cytochrome P450 system is not involved in naltrexone metabolism. Two other minor metabolites are 2-hydroxy-3-methoxy-6-naltrexol and 2-hydroxy-3-methoxy-naltrexone.
After IM injection, the naltrexone plasma concentration time profile is characterized by a transient initial peak, which occurs approximately 2 hours after injection, followed by a second peak observed approximately 2-3 days later.Opioid Antagonists: Naloxone and Naltrexone the onset of action is only slightly less rapid when it is administered subcutaneously or intramuscularly.
Renal Insufficiency : A population pharmacokinetic analysis indicated mild renal insufficiency (creatinine clearance of 50-80 mL/min) had little or no influence on VIVITROL pharmacokinetics and that no dosage adjustment is necessary.Orphan indication sponsor Jill P Smith, MD, Pennsylvania State University, 500 University Drive, Hershey, PA 17033.

Mechanism Of action Naltrexone is an opioid antagonist with highest affinity for the mu opioid receptor. Naltrexone has little or no opioid agonist activity. Naltrexone has few, if any, intrinsic actions besides its opioid blocking properties.Most commonly, these are generic drugs. 2 This drug is available at a middle level co-pay. Most commonly, these are "preferred" (on formulary) brand drugs. 3 This drug is available at a higher level co-pay.

Dosing Uses AdultPediatric Dosage Forms Strengths tablet 50mg microspheres for IM injection 380mg more. Opioid Dependence Prevention of relapse after opioid detoxification; to be used only after patient has been opioid-free for 7-10 days and after negative naloxone challenge (no symptom withdrawal.However, involvement of the endogenous opioid system is suggested by preclinical data. Naltrexone blocks the effects of opioids by competitive binding at opioid receptors. This makes the blockade produced potentially surmountable, but overcoming full naltrexone blockade by administration of opioids may result in non-opioid receptor-mediated.
