Tofenacin 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).^[1]^[2]^[3] It acts as a serotonin-norepinephrine reuptake inhibitor,^[4] and based on its close relation to orphenadrine, may also possess anticholinergic and antihistamine properties. Tofenacin is also the major active metabolite of orphenadrine and likely plays a role in its beneficial effects against depressive symptoms seen in Parkinson's disease patients.^[5]^[6]
