Vedaclidine (LY-297,802, NNC 11-1053) is a novel analgesic drug which acts as a mixed agonist-antagonist at muscarinic acetylcholine receptors, being a potent and selective agonist for the M1 and M4 subtypes, yet an antagonist at the M2, M3 and M5 subtypes.[1][2] It is orally active and an effective analgesic over 3x the potency of morphine, with side effects such as salivation and tremor only occurring at many times the effective analgesic dose.[3][4][5] Human trials showed little potential for development of dependence or abuse,[6] and research is continuing into possible clinical application in the treatment of neuropathic pain and cancer pain relief.[7]
