Comparison of the efficacy of 1% flutrimazole cream twice a day with 1% flutrimazole cream once a day for the treatment of superficial dermatophytoses

Different clinical studies have demonstrated flutrimazole's efficacy in the treatment of superficial dermatomycoses when administered either twice daily or once daily for four weeks. The aim of the present study was to compare both dosing schedules for the treatment of superficial dermatomycoses. In this randomized, controlled, double blind study, we included 84 patients suffering superficial dermatophytosis (confirmed by microscopic examination (KOH) and culture) susceptible for topical monotherapy. Forty-one patients received flutrimazole 1% twice daily (TD) and forty-three once daily (OD) for four weeks. The efficacy of treatment was evaluated by clinical and mycological criteria at the end of treatment (D28) and after four weeks without treatment (D58). Clinical and mycological cure rates on D28 were 50% with TD and 65% with OD treatment. Only considering clinical evaluation, clinical cure rates on D28 were 63% (TD) and 70% (OD). Also, clinical and mycological cure rates on D56 were 65% with TD and 72% with OD treatment. Only considering clinical evaluation, clinical cure rates on D56 were of 68% (TD) and 72% (OD). The overall tolerability was similar in both treatment groups. The efficacy assessment at the end of treatment (D28) and four weeks after treatment discontinuation (D56) showed that the OD treatment is not inferior to the TD treatment, with similar clinical and mycological cure rates and clinical cure rates in both cases. The OD administration of flutrimazole cream 1% is the most appropriate dosing schedule as it provides the same efficacy, it improves patient's compliance and the cost per day of treatment.
