Antiemetic;Dopamine antagonist

The Uses of PROCHLORPERAZINE MALEATE

Antiemetic.

What are the applications of Application

Prochlorperazine, dimaleate is a D2 dopamine receptor 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
