Treatment with Methadone or Buprenorphine Following Nonfatal Overdose Leads to Decreased Mortality

"In the 12 months after a nonfatal overdose, 2040 persons (11%) enrolled in MMT for a median of 5 months (interquartile range, 2 to 9 months), 3022 persons (17%) received buprenorphine for a median of 4 months (interquartile range, 2 to 8 months), and 1099 persons (6%) received naltrexone for a median of 1 month (interquartile range, 1 to 2 months). Among the entire cohort, all-cause mortality was 4.7 deaths (95% CI, 4.4 to 5.0 deaths) per 100 person-years and opioid-related mortality was 2.1 deaths (CI, 1.9 to 2.4 deaths) per 100 person-years.

Vivitrol and Injection Site Reactions

"VIVITROL injections may be followed by pain, tenderness, induration, swelling, erythema, bruising, or pruritus; however, in some cases injection site reactions may be very severe. In the clinical trials, one patient developed an area of induration that continued to enlarge after 4 weeks, with subsequent development of necrotic tissue that required surgical excision. In the postmarketing period, additional cases of injection site reaction with features including induration, cellulitis, hematoma, abscess, sterile abscess, and necrosis, have been reported.

Depression, Suicidality, and Vivitrol

"Depression and Suicidality

"Alcohol- and opioid-dependent patients, including those taking VIVITROL, should be monitored for the development of depression or suicidal thinking. Families and caregivers of patients being treated with VIVITROL should be alerted to the need to monitor patients for the emergence of symptoms of depression or suicidality, and to report such symptoms to the patient’s healthcare provider.

Extended Release Injectable Naltrexone (Vivitrol)

"What is VIVITROL?
"VIVITROL is a prescription injectable medicine used to:
"• treat alcohol dependence. You should stop drinking before starting VIVITROL.
"• prevent relapse to opioid dependence, after opioid detoxification.
"This means that if you take opioids or opioid-containing medicines, you must stop taking them before you start receiving VIVITROL. See “What is the most important information I should know about VIVITROL?”

Clinical Challenges and Knowledge Gaps Regarding Treatment with Vivitrol

"There are currently no specific clinical guidelines for transitioning patients with opioid use disorder to Vivitrol while minimizing the risk of precipitating withdrawal and relapse.25 However, a number of opioid detoxification and induction strategies are being investigated to assist patients transitioning to Vivitrol.90,91 The US prescribing recommendation that individuals abstain from opioids for seven to 10 days, combined with conventional methods of opioid-agonist tapering over several days, represents a delay of at least two weeks before Vivitrol can be started.

Comparison of Extended-Release Naltrexone with Buprenorphine-Naloxone

"This large multicentre, randomised, controlled, comparative effectiveness trial had five major findings. First, it was more difficult to start XR-NTX [Extended-release naltrexone] treatment than BUP-NX [sublingual buprenorphine-naloxone] treatment: 28% dropped out of treatment before XR-NTX induction versus only 6% before BUP-NX induction. Second, nearly all induction failures had early relapse. Third, in the intention-to-treat population of all patients who were randomly assigned, XR-NTX had lower relapse-free survival than BUP-NX, directly related to early induction failure.
