Comparison between the efficacy of terbinafine and itraconazole orally vs. the combination of the two drugs in treating recalcitrant dermatophytosis.

Fungal infections are a challenging to treat cutaneous condition. Approximately 20-25% of humans are affected by superficial fungal infections that invade and multiply within keratinized tissues. To compare the efficacy of either terbinafine or itraconazole orally versus the combination of the two drugs in the treatment of recalcitrant dermatophytosis. The current study included 45 patients with recalcitrant dermatophytosis who were distributed into 3 groups (each of 15 patients); Group A received terbinafine 250 mg twice a day for 4 weeks. Group B received itraconazole 200 mg twice a day for 4 weeks. Group C received terbinafine 250 mg once daily and itraconazole 200 mg once daily for 4 weeks. The patients were followed up for 12 weeks after initiation of treatment by clinical and microbiological assessment to determine the cure rate. At the end of twelve weeks, 12 (80%) patients in group A; 13 (86.7%) patients in group B and 15 (100%) patients in group C were completely cured. Despite of cure rates being higher in the combined group C; yet results were not statistically significant (p = 0.207). Clinical cure rates were non significantly higher in itraconazole + terbinafine combined group (p = 0.207). Combination of terbinafine and itraconazole had a higher clinical and mycological cure rate when compared to the use of either drug alone as monotherapy. Further randomized, multicenter, large cohort studies are warranted to validate the use of combination antifungal treatments.
