Triavil

Perphenazine is a typical antipsychotic drug. Chemically, it is classified as a piperazinyl phenothiazine. Originally marketed in the United States as Trilafon, it has been in clinical use for decades. Perphenazine is roughly ten times as potent as chlorpromazine at the dopamine-2 (D2) receptor;[1] thus perphenazine is considered a medium-potency antipsychotic.[2][3] Contents 1 Medical uses 1.1 Effectiveness 2 Side effects 2.1 Discontinua...
