What is the most effective antifungal (anti-fungal) topical treatment?

From the Guidelines

The most effective topical antifungal for vulvovaginal candidiasis is clotrimazole, as it has been shown to achieve high response rates in both uncomplicated and complicated cases 1. When it comes to treating fungal infections, the choice of topical antifungal depends on the specific type of infection being treated. For vulvovaginal candidiasis, azole medications like clotrimazole, miconazole, and ketoconazole are generally considered highly effective.

• Clotrimazole 1% or 2% cream or vaginal suppository is typically recommended for uncomplicated vulvovaginal candidiasis, with a treatment duration of 3-7 days 1.
• For complicated vulvovaginal candidiasis, topical therapy with clotrimazole or other azole medications may be necessary for a longer duration, typically 7-14 days 1.
• It's essential to note that the treatment of vulvovaginal candidiasis should not differ based on HIV infection status, as identical response rates are anticipated for HIV-positive and HIV-negative women 1.
• When using any topical antifungal, it's crucial to continue treatment for the full recommended duration, even if symptoms improve earlier, to prevent recurrence 1.
• Cleaning and drying the affected area before application and avoiding sharing personal items that could spread the infection are also important measures to take 1. The medications work by either killing fungi directly or preventing their growth by disrupting their cell membranes or inhibiting essential cellular processes. In the case of recurrent vulvovaginal candidiasis, induction therapy with a topical agent or oral fluconazole for 10-14 days, followed by a maintenance azole regimen for at least 6 months, is recommended 1. Overall, clotrimazole is a highly effective topical antifungal for treating vulvovaginal candidiasis, and its use is supported by the most recent and highest-quality evidence 1.

From the Research

Most Effective Antifungal Topical

• Terbinafine 1% cream has been shown to be a highly effective short-duration therapy for dermatophytosis of the skin 4, 5, 6
• Studies have compared the efficacy of terbinafine with other antifungal agents, such as clotrimazole, and found terbinafine to be more effective in terms of mycological cure and effective treatment 4, 6
• Terbinafine has been found to be effective against a wide variety of dermatophytes, moulds, and certain dimorphic fungi, and has fungistatic activity against Candida albicans 5, 7
• Topical terbinafine 1% formulations have been shown to be effective when applied once or twice daily for up to 2 weeks, achieving mycological cure in > 80% of patients with tinea pedis, tinea corporis/cruris, cutaneous candidiasis, and pityriasis versicolor 5, 8
• A meta-analysis of 19 studies found that terbinafine was significantly superior to placebo in terms of mycologic cure rate, and that there were no significant differences in efficacy amongst different formulations of terbinafine, treatment durations, or frequencies of application 8

Comparison with Other Antifungal Agents

• Terbinafine has been compared with clotrimazole in several studies, and has been found to be more effective in terms of mycological cure and effective treatment 4, 6
• Terbinafine has also been compared with other antifungal agents, such as miconazole, naftifine, bifonazole, and oxiconazole, and has been found to be at least as effective, if not more effective, than these agents 5, 8
• A study found that terbinafine was more effective than griseofulvin in dermatophyte onychomycosis, tinea pedis, and tinea corporis/cruris, and had comparable efficacy in children with tinea capitis 5

Treatment Duration and Frequency

• Studies have found that terbinafine can be effective in treating tinea pedis with a short treatment duration of just 1 week 4, 6
• A meta-analysis found that there were no significant differences in efficacy amongst different treatment durations or frequencies of application 8
• A study found that a novel topical solution of terbinafine, known as a film-forming solution, was effective in treating tinea pedis with a single-dose regimen 7, 8
