Alimemazine (INN), also known as trimeprazine, commonly provided as a tartrate salt, is a phenothiazine derivative that is used as an antipruritic (it prevents itching from causes such as eczema or poison ivy, by acting as an antihistamine).[3] It also acts as a sedative, hypnotic, and antiemetic for prevention of motion sickness.
Despite being structurally related to the molecule chlorpromazine, it is not used as an antipsychotic.[4]
