Bioavailability: 5-40%. Onset: 15-30 min. Duration: 24 hr REVIA® (naltrexone hydrochloride tablets USP), an opioid antagonist, is a synthetic congener of oxymorphone with no opioid agonist properties. Naltrexone differs in structure from oxymorphone in that the methyl group on the nitrogen atom is replaced by a cyclopropylmethyl group. Low-dose naltrexone has been known to have anti-inflammatory effects that reduce symptoms of and may treat inflammatory diseases and autoimmune disorders. A 2014 study suggests that LDN may be a novel anti-inflammatory agent in the central nervous system, with a specific mechanism of action affecting microglial cells.
