In a four-week, double-blind, clinical trial thirty-one patients with depressive neurosis were treated with viloxazine, doxepin, or placebo. There were no differences among the three groups in therapeutic effects. Many depressed out-patients improve on placebo. Viloxazine hydrochloride is one of a series of compounds developed to explore the central nervous system activity of the aryloxypropanolamine type of β-adreno-receptor antagonists. Initial clinical studies support the hypothesis that viloxazine has antidepressant properties in man (Bayliss et al, 1974; Bereen, 1973; Pichot et al, 1975; Tsegos and Ekdawi, 1974).
