Tapinarof cream for the topical treatment of plaque psoriasis in adults.

INTRODUCTION

Plaque psoriasis, a chronic immune-mediated skin disorder, is characterized by well-demarcated erythematous plaques with silvery scales. This condition stems from complex interactions between genetic predisposition, immune dysregulation, and environmental triggers. Tapinarof downregulates the cytokine IL-17, diminishes the inflammatory infiltrate, and provides antioxidant properties while enhancing the expression of skin barrier proteins.

AREAS COVERED: This review begins by assessing tapinarof's mechanism in treating plaque psoriasis. Subsequently, it examines the effectiveness and safety of tapinarof 1% cream in adult patients.

EXPERT OPINION: Tapinarof 1% cream, which works by activating the aryl hydrocarbon receptor, is an FDA-approved treatment for adult plaque psoriasis. This therapy introduces a novel, nonsteroidal method for addressing inflammation and skin barrier issues, potentially serving as an alternative to conventional treatments. The once-daily, convenient cream formulation and favorable safety profile may enhance patient adherence, which is often poor with topical treatments. Tapinarof also maintains disease clearance for a mean of 4 months after treatment cessation.
