Objectives: Dermatophytic infections are the common fungal infections aggravated by hot and humid climate. Terbinafine and itraconazole are commonly used oral antifungal agents for the same. However, resistance to these drugs is being seen increasingly when used in the conventional doses and duration. Therefore, this study was designed to compare the efficacy of terbinafine and itraconazole in increased dosages and duration in the treatment of tinea corporis and tinea cruris.
Materials and methods: In this randomized comparative study, patients of tinea cruris and tinea corporis were randomly divided into two groups of 160 each and were given oral terbinafine (Group I) and oral itraconazole (Group II) for 4 weeks. The scores and percentage change in scores of pruritus, scaling, and erythema were evaluated at 2 and 4 weeks.
Results: At the end of week 4, mycological cure was seen in 91.8% after 4 weeks in the itraconazole group as compared to 74.3% of patients in the terbinafine group. There was a significant improvement in percentage change in pruritus, scaling, and erythema in both the groups from 0 to 4 weeks. On comparing groups, the percentage change was significantly different in scaling from 0 to 2 weeks (5.4 vs. -4.8) and 2-4 weeks (16.7 vs. 29.6) between Group I and Group II, respectively. Clinical global improvement was better with itraconazole. Mild adverse effects such as gastrointestinal upset, headache, and taste disturbances were observed which were comparable in both the groups.
Conclusions: Itraconazole and terbinafine seem to be equally effective and safe in the treatment of tinea cruris and tinea corporis.
