(what is this?) |
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 to , 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]
