Definition

Broad spectrum antifungal agent used for long periods at high doses, especially in immunosuppressed patients. Ketoconazole (pronounced /ˌkiːtoʊˈkoʊnəzoʊl/) is a synthetic antifungal drug used to prevent and treat skin and fungal infections, especially in immunocompromised patients such as those with AIDS. Ketoconazole is sold commercially as an anti-dandruff shampoo. Ketoconazole is very lipophilic, which leads to accumulation in fatty tissues. The less toxic and more effective triazole compounds fluconazole and itraconazole have largely replaced ketoconazole for internal use. Ketoconazole is best absorbed at highly acidic levels, so antacids or other causes of decreased stomach acid levels will lower the drug's absorption when taken orally. -Wikipedia [HMDB]

Description

Ketoconazole is only found in individuals that have used or taken this drug. It is a broad spectrum antifungal agent used for long periods at high doses, especially in immunosuppressed patients. [PubChem]Ketoconazole interacts with 14-α demethylase, a cytochrome P-450 enzyme necessary for the conversion of lanosterol to ergosterol. This results in inhibition of ergosterol synthesis and increased fungal cellular permeability. Other mechanisms may involve the inhibition of endogenous respiration, interaction with membrane phospholipids, inhibition of yeast transformation to mycelial forms, inhibition of purine uptake, and impairment of triglyceride and/or phospholipid biosynthesis. Ketoconazole can also inhibit the synthesis of thromboxane and sterols such as aldosterone, cortisol, and testosterone.
