Naltrexone is contraindicated in acute hepatitis or liver failure, and its use in patients with active liver disease must be carefully considered in light of its hepatotoxic effects. Oral naltrexone is rapidly and nearly totally absorbed in the gastrointestinal tract and is metabolized almost exclusively by the liver to the primary active metabolite, 6-β-naltrexol. Peak naltrexone plasma concentrations are reached within 1 hour of dosing. The long-acting properties of naltrexone are due primarily to 6-β-naltrexol, which has an elimination half-life of 13 hours.
