Bifonazole (trade name Canespor among others [1]) is an imidazole antifungal drug used in form of ointments.
It was patented in 1974 and approved for medical use in 1983. [2] There are also combinations with carbamide for the treatment of onychomycosis.
Adverse effects
The most common side effect is a burning sensation at the application site. Other reactions, such as itching, eczema or skin dryness, are rare. [3] Bifonazole is a potent aromatase inhibitor in vitro. [4] [5]
Pharmacology
Mechanism of action
Bifonazole has a dual mode of action. It inhibits fungal ergosterol biosynthesis at two points, via transformation of 24-methylendihydrolanosterol to desmethylsterol, together with inhibition of HMG-CoA. This enables fungicidal properties against dermatophytes and distinguishes bifonazole from other antifungal drugs. [3] [6]
Pharmacokinetics
Six hours after application, bifonazole concentrations range from 1000 μg/ cm3 in the stratum corneum to 5 μg/cm3 in the papillary dermis. [3]
