Vivitrol Naltrexone Extended-Release Injectable Suspension 380mg is a medication used to help prevent relapse in those who have recently stopped using opioids or alcohol. It is a once-monthly injection that contains naltrexone, which works by blocking the effects of opioids and alcohol in the brain. This can help reduce cravings and prevent a relapse from occurring. Vivitrol is intended to be used in combination with counseling or other support programs as part of a comprehensive treatment plan for substance use disorders.

How does it work?

Vivitrol is a naltrexone extended-release injectable suspension, a medication used to treat alcohol and opioid dependence. It works by blocking the effects of endorphins, the body's natural "feel-good" chemicals, in the brain. This helps reduce the rewarding effects of alcohol and opioids, leading to decreased cravings and reduced desire to use these substances.

Naltrexone binds to and blocks the receptors in the brain that are normally activated by endorphins. By blocking these receptors, naltrexone prevents the rewarding effects of alcohol and opioids, making these substances less appealing to use. It also helps decrease the amount of dopamine released in response to alcohol and opioids, which can also reduce the reinforcing effects of these substances.

Vivitrol is an extended-release formulation, meaning it is slowly released into the body over a period of time. This allows for consistent levels of naltrexone in the body and reduces the frequency of injections needed.

Vivitrol is often used as part of a comprehensive treatment program that includes counseling and support. It is not a cure for alcohol or opioid dependence, but it can help individuals maintain abstinence and reduce the risk of relapse.
