title: Terfenadine in chronic urticaria: a comparison with clemastine and placebo.
abstract: Terfenadine, a new specific and peripherally acting antihistamine, was compared with clemastine and placebo in a prospective, randomized, double-blind, double-dummy, crossover study of the treatment of chronic urticaria. Sixty patients with chronic urticaria participated in this multicenter trial. The treatment time was two weeks per drug treatment, totalling six weeks. Terfenadine proved more effective than clemastine and was associated with significantly less sedation. Few adverse reactions were noted.
