Bifonazole. A review of its antimicrobial activity and therapeutic use in superficial mycoses.


PMID 2670516

Abstract

Bifonazole is a substituted imidazole antifungal agent structurally related to other drugs in this group. It possesses a broad spectrum of activity in vitro against dermatophytes, moulds, yeasts, dimorphic fungi and some Gram-positive bacteria. Both non-comparative and comparative clinical trials have clearly demonstrated the efficacy and safety of various formulations of bifonazole 1% (cream, gel, solution and powder) applied once daily in the treatment of superficial fungal infections of the skin such as dermatophytoses, cutaneous candidiasis and pityriasis versicolor. In comparative studies bifonazole was significantly superior to placebo and at least as effective as alternative imidazole antifungal drugs including clotrimazole, econazole, miconazole, oxiconazole and sulconazole. Preliminary studies in other superficial skin and nail infections/dermatoses suggest that bifonazole may be useful for treating onychomycoses (in a combination cream; bifonazole 1% plus urea 40%), otomycoses, erythrasma, sebopsoriasis, seborrhoeic dermatitis and rosacea. However, controlled trials are needed in each of these clinical settings to assess accurately its relative place in therapy. Thus, bifonazole is an effective and well-tolerated treatment for superficial fungal infections of the skin. Compared with the majority of topical antifungal drugs, which need to be applied at least twice daily, bifonazole offers the convenience of once daily administration, which may improve patient compliance.
