Topical corticosteroids.

Topical corticosteroids represent a frequently prescribed form of treatment for plaque-type psoriasis vulgaris. Topical corticosteroids have immunosuppressive, antimitotic, and anti-inflammatory actions that can contribute to the temporary alleviation of psoriasis. Protracted topical steroid-induced remissions are possible if psoriasis plaques can be cleared or almost cleared and then treated in an intermittent fashion, thereby limiting exposure and reducing the possibility of adverse experiences.
