Terbinafine Hydrochloride Combined With Itraconazole for Fungal Skin Diseases: A Randomized Controlled Trial

摘要

Background: Terbinafine and itraconazole are the common antifungal drugs in clinic. In vitro experiments proved that terbinafine combined with itraconazole achieves better antifungal effects. However, clinical study addressing this issue was still scarce.Study Question: Terbinafine combined with itraconazole achieves better therapeutic effects in fungal skin diseases.Study Design: Approximately 178 patients with fungal skin diseases from Meizhou People's Hospital, China, between October 2016 and October 2017 were admitted to this study. Patients were randomly distributed to 3 groups by randomly selecting random numbers and were treated with terbinafine, itraconazole, monotherapy, or combined therapy. Both patients and study investigators were unaware of grouping situations during experiments. Fifteen patients were excluded due to poor compliance, and 11 patients were excluded due to incomplete data. Finally, 152 patients were analyzed for this study.Measures and Outcomes: The therapeutic effects were evaluated by clinic symptom scores, mycology examination, the cure rate, and the cure time. Adverse events, relapse of disease, and patient's satisfaction level were recorded during follow-up.Results: In the terbinafine + itraconazole group, at 14 days after treatment, the symptom scores were significantly decreased, compared with the terbinafine or itraconazole group (P1 , 0.05, P2 , 0.05). At 28 days after treatment, the fungal infection of 37 patients was eradicated, which were significantly more than 26 patients in the terbinafine group and 19 patients in the itraconazole group (P1 , 0.05, P2 , 0.05). The terbinafine + itraconazole group also exhibited 100% cure rate of patients with fungal skin diseases, shorter cure time, and increased number of cured patients during the same treatment period, which was better than terbinafine or itraconazole monotherapy (P1 , 0.05, P2 , 0.05). In addition, no adverse events and no relapse of fungal disease were reported in the terbinafine + itraconazole group during follow-up. Ninety-eight percent patients were satisfied with the therapeutic effects of combined treatment.Conclusions: Compared with terbinafine or itraconazole monotherapy, terbinafine + itraconazole combined treatment achieves better therapeutic effects in fungal skin diseases.
