Prochlorperazine

Also Known As: Prochlorperazine, Compazine, Stemetil, Stemzine, Buccastem, Compro

Prochlorperazine (Compazine, Stemzine, Buccastem, Stemetil, Phenotil) is a dopamine (D2) receptor antagonist that belongs to the phenothiazine class of antipsychotic agents that are used for the antiemetic treatment of nausea and vertigo. It is also a highly-potent typical antipsychotic, 10-20x more potent than chlorpromazine. It is also used to treat migraine headaches. Intravenous administration can be used to treat status migrainosus.

Prochlorperazine is a phenothiazine drug. Most drugs in this category are used as anti-psychotics (neuroleptics).[1] Neuroleptic means "nerve seizing," and describes the semi-paralyzing effect these drugs have on the brain and nervous system. Stemetil is no longer being manufactured for sale in Canada as an anti-psychotic, but it is still available for treatment of nausea, etc.

It is now relatively seldom used for the treatment of psychosis and the manic phase of bipolar disorder. It has a prominent antiemetic/antivertiginoic activity and is most often used for the (short-time) treatment of nausea and vomiting and vertigo.
