Efficacy of daily oral terbinafine versus pulse fluconazole therapy in the treatment of tinea corporis, tinea cruris, and tinea faciei: A comparative study

Abstract

Introduction: Both terbinafine and fluconazole are effective systemic drugs for dermatophytosis. They can be used intermittently as pulse doses or as daily doses for the treatment of the same. Aim: The aim of this study was to assess the efficacy and safety of 1 week twice a day therapy of terbinafine and to compare it with that of a daily 2-week course of terbinafine and weekly pulse fluconazole therapy. The adverse effects and relapse rates after the completion of therapy were assessed. Materials and Methods: A study was conducted with 90 patients divided into three Groups A, B, and C. Patients were assessed at 2 and 4 weeks of starting treatment and 6 weeks following the completion of treatment. Adverse effects if any were noted. Clinical scores were calculated, and skin scraping for potassium hydroxide (KOH) examination was done. Clinical improvement was assessed. A mycological cure is defined as a negative KOH examination. Results: There was a significant decrease in clinical scores before treatment and at 2 and 4 weeks of visits. The highest clinical cure rates were attained in Group A (80%), followed by Group B (73.33%) and Group C (63.3%). Mycological cure rate at 4 weeks was highest in Group A (93.3%), followed by Group B (86.7%) and Group C (83.3%). This difference in clinical and mycological cure rates in the three groups was not found to be statistically significant. Of the patients who had responded to treatment at 4 weeks, the clinical and mycological cure was maintained in 96.4% individuals in Group A, 96.1% in Group B, and 88% in Group C at 6 weeks. Thus, the highest number of recurrences was seen in Group C, followed by Group B and Group A. All the three treatment regimens were well tolerated. Side effects were seen in 17 patients. They were mild and predominantly gastrointestinal. Conclusion: All three drugs in different regimens were found to be equally efficacious in the treatment of dermatophytic infections in our center.
