Zetidoline, A New Antipsychotic

Abstract
Summary: Zetidoline (ZTD), a compound chemically unrelated to any available antipsychotic, with selective dopamine receptor-blocking properties, was compared with haloperidol (HLP) in a double-blind study on 56 in-patients who had either first episodes or acute relapses of schizophrenia. ZTD was found to be safe, as effective as HLP, and to produce significantly fewer extrapyramidal side-effects (EPS).
