abstract:Tofenacin (INN; Elamol, Tofacine, Tofalin), or tofenacin hydrochloride (USAN), also sometimes called mono-N-desmethylorphenadrine, is an antidepressant drug with a tricyclic-like structure which was developed and marketed in the United Kingdom and Italy in 1971 and 1981, respectively, by Brocades-Stheeman & Pharmacia (now part of Astellas Pharma). It acts as a serotonin-norepinephrine reuptake inhibitor, and based on its close relation to orphenadrine, may also possess anticholinergic and antihistamine properties.
