Mechanism of action and pharmacodynamics Lamizila

Lamizil Terbinafine is an antimycotic compound that is active against a wide range of fungal microflora.It has a fungistatic and fungicidal effect, that is, it destroys fungal cells and prevents their reproduction and growth of colonies.Even at low concentrations, this substance can destroy dermatophytes, as well as mold and individual dimorphic fungi.Terbinafine also allows you to cope with candidiasis, i.e., diseases caused by yeast-like fungi of the genus Candida.

The action of the active component of the drug Lamisil is aimed at suppressing the biosynthesis of sterols in the fungal cell in the early stages.It also inhibits the enzyme squalene epoxidase, which leads to a deleterious intracellular accumulation of squalene for microflora.

After taking Lamizil tablets, more than 70% of terbinafine is absorbed into the human digestive tract, and the level of bioavailability is estimated at around 50%( food intake is practically unaffected).The maximum plasma concentration is fixed 1.5 hours after taking the drug.About 99% of the absorbed terbinafine is conjugated( interacts) with plasma proteins.With external application of Lamizil, the active ingredient freely passes the dermis, accumulating in the stratum corneum.Terbinafine has the property of accumulating in sebum, so during the course of treatment, its therapeutic concentrations in the hair follicles and the sebum-rich areas of the skin are achieved.Already in the first week of antifungal therapy the drug penetrates into the nail plates.Active metabolites and unchanged substance are excreted( excreted) by the kidneys.
