Clofenetamine, also known as phenoxethamine or as Keithon, is a drug described as a tranquilizer, antihistamine, anticholinergic, and antiparkinsonian agent. It is a derivative of diphenhydramine and is closely structurally related to mephenhydramine, chlorphenoxamine, and embramine, among other drugs.
