Naltrexone is a derivative of noroxymorphone that is the N-cyclopropylmethyl congener of naloxone. It competitively binds to mc, κ, δ and μ receptors in the CNS and may block the effects of endogenous opioids, thus leading to the antagonization of most of the subjective and objective effects of opiates. The metabolite of naltrexone, 6-β-naltrexol, is also an opiate antagonist and reduces the activity of the drug. Further read: https://
