This study aims to compare the efficacy and safety of the combination drug Clotrimazole+Lactulose with the monocomponent product Canesten® (clotrimazole) in adult women diagnosed with candidal vulvovaginitis. The primary objective was to confirm the superiority of the combination drug in terms of clinical and microbiological response on Day 25 of the study.

The study was conducted using an adaptive design to evaluate the impact of lactulose on the course of fungal infections. The primary endpoint was the proportion of patients achieving clinical and microbiological recovery on Day 25 (Visit 4). Secondary endpoints included assessment of symptom severity, changes in Lactobacillus content, and patient satisfaction with therapy. Participants were randomized into three groups: Clotrimazole+Lactulose, Canesten, and Lactulose.
