ZORYVETM (Roflumilast) Cream: A Topical Phosphodiesterase-4 Inhibitor for the Treatment of Psoriasis.

ZORYVETM (roflumilast) cream is a topical phosphodiesterase-4 (PDE-4) inhibitor that has been recently approved for the treatment of plaque psoriasis. It is also indicated for use in intertriginous areas. Roflumilast, the active ingredient, inhibits PDE-4, leading to the suppression of pro-inflammatory immune responses in psoriatic lesions. Two phase 3 clinical trials have demonstrated the efficacy of once daily application of roflumilast to treat plaque psoriasis in patients aged 12 years and older. At week 8, an investigator's global assessment score of 0 or 1 with a grade 2 improvement from baseline, the primary efficacy end point, was observed in 39.1% (225/576) of patients applying roflumilast, compared to 6.6% (20/305) of patients applying vehicle. Common adverse events reported were diarrhea, headache, insomnia, nausea, pain at application site, upper respiratory tract infection, and urinary tract infection.
