Side-effect profile of acitretin therapy in psoriasis.

Abstract

Acitretin, the principal and free acid metabolite of etretinate, was used to treat patients with stable, plaque-type psoriasis. For the first 8 weeks, 38 patients received placebo or acitretin, 10, 25, 50, or 75 mg daily, in a double-blind manner. After the double-blind phase, the patients were allowed to continue for a total of 6 months of acitretin therapy at an average dosage of 50 mg/day. When the patients flared after stopping therapy, an additional 6-month course of acitretin therapy was offered. Acitretin, which was as effective as etretinate, had to be given at a dosage of 50 mg/day or more to obtain a significant benefit. Side effects frequently occurred in patients receiving acitretin, 25 mg/day or more, but were generally mild and did not warrant discontinuation of therapy. They were similar to those of etretinate therapy; cheilitis, peeling of palms and soles, and alopecia occurred most frequently. The most common abnormal laboratory test results were elevations in serum triglycerides and, to a lesser extent, serum cholesterol and liver transaminase levels. Acitretin, in view of its much shorter half-life and similar efficacy and side-effect profile compared with etretinate, may be a preferable therapy for psoriasis, especially in women of childbearing age.
