Class I topical corticosteroid use by psoriasis patients in an academic practice

Psoriasis is a chronic skin disorder that can have a profound impact on the quality of life of patients. The treatment of psoriasis is complicated by the availability of numerous topical agents, systemic agents, and phototherapy. Of the topical preparations available, the ultra-high potency, or Class I steroids, have an important role in treating psoriasis. Their use is most appropriate for the treatment of plaques in regions excluding the face, axilla, groin and genitals.

The purpose of this study was to examine the prescribing patterns of Class I topical corticosteroids within a large academic dermatology practice for patients with all types of psoriasis.

A retrospective chart review of 650 patients with psoriasis from an academic dermatology practice was performed. Class I steroid use was defined as those patients who were observed to be currently using clobetasol propionate, halobetasol propionate, diflorasone, or augmented betamethasone dipropionate.

A total of 79% of patients were prescribed topical steroids of any class while 46% of patients were prescribed a Class I steroid. In all, 58% of patients who received topical steroid therapy received a Class I agent; 11% of patients prescribed Class I steroids also received systemic therapy for their psoriasis. Conversely, 35% of patients who received systemic therapy were also receiving Class I topical therapy.

In our department, Class I topical steroids are commonly used in the treatment of psoriasis. The superpotent topicals are often used as an adjunct to systemic therapy and will likely remain a mainstay of psoriasis therapy.
