© 2020 Faculty of Medicine Siriraj Hospital, Mahidol University. Objective: To compare the efficacy and safety of a generic desoximetasone cream (Topoxy) with the reference form, Topicorte, for the treatment of scalp psoriasis. Methods: A randomised, double-blind, controlled study was conducted. Altogether, 105 patients with psoriasis lesions covering more than 10% of the scalp were randomised into three groups. The first, second and third groups received a placebo, Topoxy and Topicorte, respectively. The scalp psoriasis severities were assessed at weeks 0, 2, 4 and 8, using the Investigator Global Assessment (IGA) scale and Total Sign Score (TSS). The safety profiles of the products were assessed by the patients and physicians. Results: Topoxy and Topicorte were significantly more effective than the placebo in achieving at least a two-grade improvement in the IGA score from baseline at weeks 2, 4 and 8, and there were no significant differences between Topoxy and Topicorte. The TSS of both creams were significantly lower than that of the placebo at weeks 2, 4 and 8. All patients tolerated well to the therapy. Conclusion: Topoxy and Topicorte had comparable efficacies for scalp psoriasis. The medications were superior to the placebo in all parameters, and had a good safety profile.
