Terbinafine hydrochloride is an antifungal, which is highly hydrophobic and tends to accumulate in hair, skin, nails, and fatty tissue.

Terbinafine hydrochloride is a white fine crystalline powder that is freely soluble in methanol and dichloromethane, soluble in ethanol, and slightly soluble in water.

Like other allylamines, terbinafine inhibits ergosterol synthesis by inhibiting squalene epoxidase, an enzyme that is part of the fungal cell membrane synthesis pathway. Because terbinafine prevents conversion of squalene to lanosterol, ergosterol cannot be synthesize.

Function & Application: 
Terbinafine hydrochloride is a broad - spectrum antifungal drug for dermatology. It can specifically disrupt the late biological decomposition of sterols in fungi, selectively inhibit the activity of squalene cyclocyoxidase in fungi, and block the reaction of squalene epoxidation in the process of fungal cell membrane formation, so as to kill or inhibit fungi. Apply to treat skin candida disease, such as tinea pedis, tinea pedis, tinea cruris, tinea systemis and tinea versicolor, also be the best medicaments that treats fingernail at present.
