WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 573663

CAS#: 36506-71-5 (R-isomer maleate)

Description: Trimeprazine 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). It also acts as a sedative, hypnotic, and antiemetic for prevention of motion sickness. Although it is structurally related to drugs such as chlorpromazine, it is not used as an antipsychotic.
