A randomized, double-blind, vehicle-controlled study of 1% pimecrolimus cream in adult patients with perioral dermatitis.

BACKGROUND

Perioral dermatitis (POD) is a common dermatosis without standard therapy.

OBJECTIVE

We sought to evaluate pimecrolimus cream 1% in POD.

METHODS

We conducted a multicenter, randomized, double-blind, parallel-group study in adult patients with POD treated twice daily with pimecrolimus cream 1% or vehicle until clearance for up to 4 weeks. Follow-up took place 4 and 8 weeks after treatment.

RESULTS

Patients treated with pimecrolimus had an average POD Severity Index score of 2.6 compared with 3.5 for patients treated with vehicle. Both groups had baseline scores of 5.2. The between-group difference was 0.9 (95% confidence level 0.4, 1.4, P = .0011). Patients with history of topical corticosteroids benefited most. Pimecrolimus-treated patients reported greater improvement in quality of life. There were no group differences regarding safety.

LIMITATIONS: Pimecrolimus vehicle is not a true placebo.

CONCLUSIONS

Pimecrolimus rapidly improves clinical symptoms and quality of life of patients with POD, being most effective in corticosteroid-induced POD.
