Description and Uses

This drug does not have agonistic properties. It is similar to naloxone in terms of pharmacological characteristics; however, it differs in two important ways—long-lasting action and that its metabolite 6-β-naltrexol is also a strong antagonist. Naltrexone is potentially hepatotoxic. Naltrexone is used for blocking pharmacological effects of opioids upon their overdose.

anthelmintic, teniacide
