Terbinafine belongs to the group of allilamines and has a broad spectrum of antifungal action. In low concentrations it has fungicidal effect on dermatophytes Trychophyton spp. (T. rubrum, T. mentagrophytes, T. tonsurans, T.verrucosum, T.violaceum), Microsporum can is, Epidermophyton floccosum, yeast fungi, mainly Candida albicans. On Candida spp. fungi and their mycelial forms it has fungicidal or fungistatic effect depending on the fungus species.
Terbinafine disrupts the early stage of biosynthesis of the main component of the cell membrane of the fungus (ergosterol) by inhibiting the enzyme squalene epoxidase.
In oral administration it is not effective in the treatment of variegated herpes caused by Pityrosporum ovale, Pityrosporum orbiculare (Malassezia furfur).
In oral administration it is well absorbed over 70%; absolute bioavailability due to the “first pass” effect is reduced by 40%. After a single oral dose of 250 mg, time to maximum concentration (TCh) is about 2 hours; maximum concentration (TCh) is approximately 1 µg/ml. Area under curve “concentration – time” (AUC) is 4.5 mcg*h/ml, AUC increases by 20% when concomitantly taken with food. With prolonged use Stah increases by 25%, AUC – 2.5 times. Effective elimination half-life (T1/2) is about 36 h, terminal T1Y 200-400 h (indicates prolonged excretion from skin and adipose tissue). Equilibrium concentration (Css) is independent of age. Plasma concentration of terbinafine is independent of sex.
The binding to plasma proteins is more than 99%. It is rapidly distributed in the tissues, penetrates into the dermal layer of the skin and nail plates. It penetrates into the secretion of sebaceous glands and accumulates in high concentrations in hair follicles, hair, skin and subcutaneous tissue.
It is subjected to significant biotransformation, the resulting metabolites do not have antifungal activity. 70% is excreted by the kidneys. It does not accumulate in the body. The age of patients does not affect the pharmacokinetics of terbinafine, but elimination may be reduced with renal or hepatic lesions, leading to high concentrations of terbinafine in the blood. It is excreted with breast milk.

How to take, the dosage
Orally in adults – 250 mg/day in 1 or 2 doses.
The duration of treatment depends on indications and severity of infection: in skin lesions – 2-4 weeks, in nail lesions – from 6 weeks to 4 months or more. For children with body weight over 40 kg – 250 mg/day, 20-40 kg – 125 mg/day, up to 20 kg – 62.5 mg/day.
Applied externally 1-2 times a day for 1-2 weeks.
Drugs that cause induction of microsomal liver enzymes increase clearance terbinafine; drugs that inhibit microsomal liver enzymes decrease clearance terbinafine.
