What does Naltrexone mean?
Naltrexone is a pure opioid receptor antagonist that competitively blocks mu, kappa, and delta opioid receptors. Unlike naloxone, it has a long half-life and is active orally. It is FDA-approved for both alcohol use disorder and opioid use disorder. It works by blocking the reinforcing effects of alcohol and opioids, reducing cravings and relapse rates. It requires patients to be opioid-free for 7–10 days before initiation to avoid precipitated withdrawal.
