Naltrexone. Naltrexone is taken once a day or three times a week as a pill or as a once-a-month injection called Vivitrol. Although it can have some side effects, they tend to be mild and are rarely dangerous. Naltrexone can be prescribed by any physician or trained medical provider and does not require a special clinic or program. It can reduce cravings for opioids and blocks the effects of opioids on the brain, which can stop a person from getting “high.” However, it does not reduce
Naltrexone. Naltrexone was first synthesized in 1965 and approved by the FDA for the oral treatment of opioid dependence in 1984, with the brand name Trexan. Later it was approved for the oral treatment of alcohol dependence in 1995, when the brand name was changed by DuPont to ReVia. A depot formulation for intramuscular injection was approved by the FDA under the brand name Vivitrol for alcohol dependence in 2006 and opioid dependence in 2010. Typical oral doses are 50 to 100 mg daily, with a once-monthly intramuscular formulation also available. At these doses, Naltrexone has been shown to function as a nonselective opioid antagonist with a high affinity for µ opioid receptors, which decreases addiction cravings (Xxxxxxxxxx, Xxxxxxx et al. 2017, Opioid Agonists & Antagonists. Basic & Clinical Pharmacology, 14e. X. X. Xxxxxxx. New York, NY, XxXxxx-Xxxx Education). However, there is a risk that patients who are non-compliant with oral naltrexone may experience opioid intoxication simply by skipping doses of naltrexone. Oral bioavailability is also variable from patient to patient, largely due to first-pass metabolism. Thus, naltrexone is pharmacologically effective, but may be ineffective in a real world setting without counseling and strong patient support (Minozzi, 2011, Oral naltrexone maintenance treatment for opioid dependence. Chchrane Database Syst Rev(4), CD001333). There are also multiple generic Naltrexone tablets available on the market for oral administration.
