What is "perphenazine"

n. A potent anti-psychotic drug.

n. tranquilizer and antidepressant (trade name Triavil) sometimes used as an antiemetic for adults [syn: Triavil]

Perphenazine is a typical antipsychotic drug. Chemically, it is classified as a piperazinyl phenothiazine. Originally marketed in the US as Trilafon, it has been in clinical use for decades.

Perphenazine is roughly five times as potent as chlorpromazine; thus perphenazine is considered a medium-potency antipsychotic.
