1.1. What Is Naltrexone and How Does It Aid in Addiction Recovery?

Naltrexone is a medication primarily used to treat alcohol and opioid use disorders. It functions as an opioid antagonist, which means it blocks the effects of opioids in the brain. Here’s a detailed explanation of how naltrexone works and how it aids in addiction recovery:

Mechanism of Action:

Opioid Antagonist: Naltrexone binds to opioid receptors in the brain without activating them. By doing so, it prevents opioid drugs (like heroin, morphine, and prescription painkillers) from attaching to these receptors and producing their euphoric and analgesic effects.
Reduces Cravings: While naltrexone’s primary action is to block opioid effects, it also helps reduce cravings for both opioids and alcohol. The exact mechanism for craving reduction is not fully understood but is believed to involve the modulation of the brain’s reward system.
Non-Addictive: Naltrexone itself is not addictive and does not produce any euphoric effects. This is a significant advantage over other medications used in addiction treatment, such as opioid agonists or partial agonists.

Forms of Naltrexone:

Oral Naltrexone (ReVia, Depade): This is a pill form that is typically taken once daily. The usual dose is 50 mg per day, but this can be adjusted by a healthcare provider based on the individual’s needs and response to the medication.
Injectable Extended-Release Naltrexone (Vivitrol): This is an injectable form that is administered intramuscularly once a month. Each injection contains 380 mg of naltrexone. Vivitrol offers the advantage of improved adherence since it eliminates the need for daily pills.

How Naltrexone Aids in Addiction Recovery:

Prevents Relapse: By blocking the effects of opioids, naltrexone prevents individuals from experiencing the “high” associated with opioid use. This can significantly reduce the likelihood of relapse, as the reinforcing effects of the drug are eliminated.
Reduces Alcohol Cravings: Naltrexone can reduce cravings for alcohol, helping individuals decrease their alcohol consumption.
Supports Comprehensive Treatment: Naltrexone is most effective when used as part of a comprehensive treatment plan that includes counseling, behavioral therapies, and social support. Medication alone is not sufficient to address the complex factors underlying addiction.
Restores Brain Function: Chronic opioid or alcohol use can disrupt the brain’s natural reward system. By blocking the effects of these substances, naltrexone allows the brain to gradually restore its normal function, which can further reduce cravings and improve overall well-being.
