What this trial studies

This clinical trial aims to compare the effectiveness of a zinc-containing vaginal gel and oral fluconazole in treating vulvovaginal candidiasis (VVC) and preventing its recurrence. A total of 76 healthy, nonpregnant women aged 18 and older with symptomatic acute VVC will be randomly assigned to receive either fluconazole alone or fluconazole followed by the zinc gel treatment. Participants will undergo clinical assessments and laboratory tests at baseline and during follow-up visits to monitor symptoms and infection recurrence. The study seeks to determine if the addition of zinc gel can reduce reinfection rates compared to standard fluconazole treatment alone.

Who should consider this trial

Good fit: Ideal candidates are healthy, nonpregnant women aged 18 and older with symptomatic acute vulvovaginal candidiasis.

Not a fit: Patients with non-albicans Candida species or those with recent antifungal treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the recurrence of vaginal yeast infections in women.

How similar studies have performed: While the use of zinc in vaginal treatments is not widely studied, similar approaches have shown promise in managing recurrent infections.
