Naltrexone works by binding to the opioid receptors in the brain, effectively blocking the euphoric and sedative effects of drugs like heroin, morphine, and other opioids. This action helps to reduce the desire to take opioids and can also help in maintaining abstinence in individuals recovering from alcohol use disorder. By preventing the rewarding effects associated with substance use, naltrexone assists in diminishing the reinforcement of addiction behaviors.
