Nicotinamide in the Treatment of Psoriasis

Isfahan University of Medical Sciences66 enrolled

Overview

This study will determine if combination of topical calcipotriol and nicotinamide is more effective than calcipotriol alone in treatment of psoriasis.

Current treatment strategies of psoriasis are not completely satisfactorily. By inhibiting inflammatory cytokines, nicotinamide may enhance the effects of current topical treatments. Preliminary studies have shown that nicotinamide, which is a vitamin B derivative, is effective in the treatment of psoriasis. According to lack of data, we will investigate the beneficial effects of adding nicotinamide to calcipotriol for patients with mild to moderate psoriasis.
