Efficacy of 15% azelaic acid in psoriasis vulgaris: a randomized, controlled clinical trial.

Abstract

The results of our study showed that 15% azelaic acid gel was effective in reduction of purities, scaling and hyperkeratosis of psoriasis plaques. This treatment was also effective in reduction of skin involvement with psoriasis. It is recommended that a longer study be performed that can better evaluate the efficacy of this treatment against plaque-type psoriasis.
