摘要

Topical antifungal treatment is a mainstay of therapy for Seborrehic Dermatitis (SD). Although the amidazole and ciclopyridine antifungals have been extensively studied, few clinical efficacy data are available for topical allylamine therapy in SD. The objective of this open-label exploratory study was to evaluate the efficacy and safety of natifine HCl 1% gel applied twice daily for 4 weeks, as topical treatment of moderate SD of the scalp. Nine subjects (5 men, 4 women) with a mean age of 56 (33-81) years with SD of the scalp were enrolled and made 4 visits to the site. At Visit 1 (Week 0), subjects were screened, enrolled, baseline efficacy data were obtained, and treatment was initiated. Subjects returned at Week 2, Week 4 (end of treatment), and Week 6 for efficacy and safety assessments. Efficacy was evaluated by changes from baseline in investigator-rated scores on 0-5-grade scales: (1) SD Global Evaluation Scale (SDGES), (2) Erythema Severity Scale, (3) Scaling Severity Scale, (4) % Scalp Involvement Scale, and subject-rated scores on the (4) Itching Severity Scale, and (5) Global Improvement Scale, where 0=none and 5=most severe. Mean severity scores for the SDGES and % Scalp Involvement scales progressively declined (improved) 66% and 54% from respective baseline levels at Week 6. Mean erythema rating decreased 38% from baseline and scaling decreased 50% from baseline by Weeks 4 and 6. Itching improved in 5 of 9 (56%) subjects by the end of treatment. A total of 8 of 9 (89%) subjects rated their symptoms as improved from baseline at the end of treatment and Week 6. There were no treatment-related adverse events during the study. These results suggest that naftifine 1% gel applied twice daily for 4 weeks is effective and safe topical treatment for moderate SD of the scalp.
