Product Description: Terbinafine is an allylamine with a range of antifungal activity. It is fungicidal against dermatophytes, moulds and certain dimorphic fungi. Terbinafine is either fungicidal or fungistatic against yeasts, depending on the species. Terbinafine interferes with fungal ergosterol biosynthesis by inhibiting squalene epoxidase in the fungal cell membrane at an early stage. This leads to a deficiency in ergosterol and to intracellular accumulation of squalene, resulting in fungal cell death. Terbinafine is highly effective in fungal infections of the skin, hair and nails caused by Trichophyton spp., Microsporum spp. and Epidermophyton floccosum. It is also effective against yeast infections of the skin, principally those caused by the genus candida. Topical terbinafine appears to be effective in pityriasis versicolor due to Pityrosporum arbiculare. How To Use: Terbinafine tablet is essential for hair or nail infections: The usual oral dose: Terbinafine 250 mg daily for 2 to 12 weeks depending upon the infection. Finger nail onychomycosis: Terbinafine 250 mg once daily for 6 weeks. Toe nail onychomycosis: Terbinafine 250 mg once daily for 12 weeks.
