About

Terbinafine is an antifungal medication belonging to the allylamine class, primarily used to treat various fungal infections of the skin, hair, and nails. Its mechanism of action involves inhibiting squalene epoxidase, a key enzyme in the fungal ergosterol biosynthesis pathway. This inhibition leads to an accumulation of squalene within the fungal cell, which is toxic and ultimately causes fungal cell death. This fungicidal action makes it highly effective against dermatophytes such as Trichophyton, Microsporum, and Epidermophyton floccosum species, which are common culprits in conditions like onychomycosis, tinea corporis, tinea cruris, and tinea pedis.

The lipophilic nature of terbinafine allows it to concentrate in the stratum corneum, hair follicles, and nail beds, providing sustained antifungal activity even after the completion of treatment. This characteristic is particularly beneficial for nail infections, where prolonged drug presence is crucial for successful eradication. Terbinafine is available in both oral and topical formulations, offering flexibility in treatment depending on the severity and location of the fungal infection, making it a cornerstone in dermatological antifungal therapy.
