Description

Terbinafine 250mg 30 tablets

Pharmacological action
Antifungal groups of allylamine. Acts by inhibition of squalene epoxidase in the fungal cell membrane. This leads to a deficiency of ergosterol and intracellular accumulation of squalene, which causes cell death of the pathogen.

It has a fungicidal effect on dermatophytes, mold and some dimorphic fungi, yeast and yeast-like fungi. On some kinds of yeast fungi can act fungistaticeski.

Active against pathogens of dermatomycosis (Trichophyton /including Trichophyton rubrum, Trichophyton mentagrophytes, Trichophyton tonsurans, Trichophyton verrucosum, Trichophyton violaceum/, also Microsporum canis and Epidermophyton floccosum); yeast fungi of the genus Candida (mainly Candida albicans); pathogen of multi-colored lichen (lichen Malassezia furfur).

During the first few weeks after starting terbinafin accumulates in the skin and nail plates in concentrations that provide a fungicidal effect.
