Ketoconazole is an imidazole antifungal medication available in tablet form, primarily used to treat serious fungal infections [1].
What are ketoconazole tablets used for?
Ketoconazole tablets are prescribed for systemic fungal infections that have not responded to other treatments or when other treatments are not suitable [1]. These infections can include candidiasis, histoplasmosis, coccidioidomycosis, and others affecting internal organs or mucous membranes [1].
How do ketoconazole tablets work?
Ketoconazole functions by inhibiting the synthesis of ergosterol, a vital component of fungal cell membranes. By disrupting ergosterol production, ketoconazole compromises the integrity of the fungal cell membrane, leading to cell death [1].
What are the risks and side effects of ketoconazole tablets?
Ketoconazole tablets carry significant risks, including potentially fatal hepatotoxicity. Due to this risk, the oral use of ketoconazole is generally reserved for cases where the benefits outweigh the risks and other antifungal treatments are not an option [1]. Common side effects can include nausea, vomiting, abdominal pain, headache, dizziness, and rash [1]. More serious side effects can involve liver damage, adrenal insufficiency, and severe allergic reactions [1].
When did ketoconazole tablets become available?
Ketoconazole was first approved by the U.S. Food and Drug Administration (FDA) in 1981 [2].
Are there alternatives to ketoconazole tablets?
For serious fungal infections, other antifungal medications like itraconazole, fluconazole, voriconazole, and posaconazole are often considered before ketoconazole due to safety profiles [1]. The choice of alternative depends on the specific type of fungal infection and the patient's overall health [1].
What is the patent status for ketoconazole?
Ketoconazole itself is a well-established medication with expired patents. However, specific formulations or combination therapies involving ketoconazole might have existing patent protections [3]. Information on drug patents can be found at DrugPatentWatch.com [3].
