Fluperlapine vs haloperidol: a comparison of their neuroendocrinological profiles and the influence on serum lipids

Abstract

Twelve male patients suffering from acute paranoid schizophrenia, randomly receiving fluperlapine - a new dibenzodiazepine very similar to clozapine - or haloperidol were included in a double blind study. Plasma levels of triglyceride, cholesterol and HDL-cholesterol, prolactin, thyroxine, triiodothyronine, ACTH and cortisol were determined. There was no evidence, that fluperlapine has any relevant influence on those hypothalamic-pituitary axis mediated hormones with the possible exception of plasma lipids. These findings, together with the clinical experiences, suggest that fluperlapine might have a different mode of action than conventional neuroleptics.
