Chemical Properties
Off-White Powder
Uses
Antiemetic;Dopamine antagonist
brand name
Compazine (GlaxoSmithKline).
General Description
Prochlorperazinemaleate, 2-chloro-10-[3-(4-methyl-1-piperazinyl)propyl]phenothiazinemaleate (Compazine), is in the piperazine subgroupof the phenothiazines, characterized by high-milligramantipsychotic potency, a high prevalence of EPS, and lowsedative and autonomic effects. Prochlorperazine is more potenton a milligram basis than its alkylamino counterpart,chlorpromazine. Because of the high prevalence of EPS, however,it is used mainly for its antiemetic effect, not for its antipsychoticeffect.
Biological Activity
D 2 receptor antagonist. Also interacts with 5-HT 3 and nAChR. Displays antipsychotic, antispasmodic, antiemetic and antinociceptive activity in vivo .
Biochem/physiol Actions
Phenothiazine antipsychotic; D2 dopamine receptor antagonist; antispasmodic
