Ketoconazole, a synthetic imidazole dioxolane derivative, belongs to the antifungal class of drugs. Ketoconazole is indicated for the treatment of infections like fungal, ringworm and yeast and against Cushing’s disease (hyperadrenocorticism). The drug is efficient against serious fungal infections like coccidoidomycosis, blastomycosis and cryptococcosis, which affect lymph nodes, eyes, bone, skin and respiratory tract (lungs). The active ingredient, Ketoconazole, interacts with the formation of fungal cell wall, inhibiting the growth of the fungal organisms. However, the medication is not effective against infections triggered by bacteria, mites, viruses and parasites (intestinal worms).
