A Comparative Study of Oxypertine and Trifluoperazine in Chronic Schizophrenia—A New Application of the Wing Rating Scale

Abstract
Thirty-five chronic schizophrenic women patients completed a sixteen-week double-blind within-patient comparison of a new non-phenothiazine compound, oxypertine (WIN. 18,501), with trifluoperazine (Stelazine). Changes in four typical symptoms and in 12 behaviour characteristics were assessed by a new application of the Wing rating scale.
