Active substance - ketoconazole, an imidazole-dioxolane derivative. It has fungicidal and fungistatic action against dermatophytes (Trichophyton spp., Epidermophyton floccosum, Microsporum spp.), yeast fungi (Candida spp.), dimorphic fungi and eumycetes, Pityrosporum spp..
The mechanism of action is the inhibition of ergosterol synthesis and membrane lipids required for synthesis of the cell wall of fungi (mushrooms lose their ability to form colonies and filaments),and impaired permeability of the cell wall. Inhibits biotransformation of blastospore Candida albicans in invasive forms.
The drug is active against staphylococci and streptococci.
