<unk>  is known to have this pharmacology: * Nonselective mACh receptor antagonist (anticholinergic, 58% as potent as atropine) Various monographs and package inserts, nursing manuals, journal articles and so forth have proposed the theory that this anticholinergic (atropine-like) activity, NMDA antagonism and possible local anaesthetic and miscellaneous analgesic effects may be the reason for<unk> 's efficacy against muscle and other pain. These reasons are behind the use of<unk>  and other drugs of a number of types which are used with paracetamol, aspirin, naproxen, and similar agents with or without opioid analgesics to more effectively manage pain of various types. * H1 receptor antagonist (antihistamine) * NMDA receptor antagonist (Ki value of 6.0 ± 0.7 μM, one hundred times less potent than phencyclidine, which binds with a Ki of 59 nM) * NDRI (norepinephrine and dopamine reuptake inhibitor) * Nav1.7, Nav1.8, and Nav1.9 sodium channel blocker * HERG potassium channel blocker
