Definition
Naltrexone is a medication primarily used to manage alcohol or opioid dependence. It works by blocking the euphoric and sedative effects of these substances, making it less rewarding to use them. Think of it as putting a lock on the door to addiction. Unlike naloxone, it's longer-acting and used for maintenance rather than emergency overdose reversal. It helps people stay sober by reducing cravings and preventing relapse. Naltrexone is often part of a comprehensive treatment plan.
