What type of infections is Ketoconazole primarily used to treat?

Ketoconazole is primarily used to treat fungal infections. It is an antifungal medication that works by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes. By disrupting the integrity of the cell membrane, Ketoconazole helps to eliminate or control fungal pathogens.

This medication is effective against a variety of fungal infections, including dermatophyte infections such as athlete's foot and ringworm, as well as for more systemic fungal infections like candidiasis. Its use is particularly significant in cases where other antifungal agents may be less effective or when the fungal organisms are resistant.

Bacterial, viral, and parasitic infections are caused by entirely different types of pathogens, for which different classes of medications are used. Therefore, choosing Ketoconazole for the treatment of any of these types of infections would not be appropriate due to its specific action against fungi.
