Alimemazine (INN), also known as trimeprazine (former BAN and USAN; trade names Nedeltran, Panectyl, Repeltin, Therafene, Theraligene, Theralen, Theralene, Vallergan, Vanectyl, or Temaril), 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).[1] It also acts as a sedative, hypnotic and anti-emetic for prevention of motion sickness. Although it is structurally related to drugs such as chlorpromazine (Thorazine), it is not used as an anti-psychotic treatment.[2] The elimination half-life is approximately 5 hours.[3]

In veterinary use, the combination of alimemazine and prednisolone is licensed as an anti-pruritic and anti-tussive in dogs.

Chemistry

Alimemazine is synthesized by alkylating phenothiazine with 1-dimethylamino-2-metylpropylchloride.[4]
