An update on topical therapies for psoriasis.

Abstract

Topical therapies are a mainstay of treatment for mild psoriasis and may be a useful adjunct in treatment of moderate-to-severe psoriasis. This review summarizes recent advances in topical therapies for psoriasis and currently available treatments. Topical aryl hydrocarbon receptor modulators (tapinarof) and topical phosphodiesterase-4 inhibitors (roflumilast) have been proven effective in randomized controlled trials for psoriasis. Although topical JAK inhibitors have also been studied, none are currently licensed for treatment of psoriasis. Topical corticosteroids and vitamin D analogues remain the most commonly used and widely available topical treatments for psoriasis. Cost may limit use of novel topical agents. Although the novel topical agents tapinarof and roflumilast are licensed for treatment of psoriasis by the FDA in the United States, they have not yet been licensed in Europe, and it remains to be seen whether they will be limited by cost.
