Comparison of betamethasone dipropionate lotion with salicylic acid (Diprosalic) and clobetasol propionate lotion (Dermovate) in the treatment of psoriasis of the scalp.

A double-blind comparison was made between Diprosalic and Dermovate lotions in fifty-one patients with psoriasis of the scalp. Both preparations were highly effective. No significant difference in efficacy between the preparations could be demonstrated after 3 weeks treatment except for antipruritic effect, in this respect Diprosalic being superior to Dermovate. Only three patients (two in the Dermovate group, and one in the Diprosalic group) experienced minor adverse reactions. Plasma cortisol levels were determined in seventeen of the patients and no significant influence on the adrenal function could be shown on the part of either of the preparations.
