Background: In the treatment of atopic dermatitis, pimecrolimus has high antipruritic effects.
Objective: To investigate the efficacy of 1% pimecrolimus cream in comparison to 1% hydrocortisone cream in non-atopic prurigo nodularis (PN).
Methods: A randomized, controlled, double-blind study with intraindividual randomization was done in 30 patients (17 females, 13 males; mean age 58.5 years) with PN.
Results: Pruritus intensity decreased significantly (p < 0.001) on both treated sides as early as after 10 days of treatment; scratch lesions improved (p < 0.001). Quality of life as assessed by the Dermatology Life Quality Index improved significantly. However, a significant advantage of pimecrolimus over hydrocortisone was not found.
Conclusion: The results suggest that the non-steroid pimecrolimus is an effective alternative for PN treatment.
