What is the primary action of Nizoral (ketoconazole) related to cortisol levels?

• A. Increases cortisol levels
• B. Reduces levels of testosterone and cortisol
• C. Inhibits testosterone production
• D. Enhances cortisol production

Answer: (B)

Nizoral (ketoconazole) primarily acts as an antifungal agent, but it also has significant effects on hormone production. It works by inhibiting the synthesis of steroids in the adrenal glands, which includes cortisol and testosterone. This suppression of steroidogenesis leads to a reduction in the levels of both testosterone and cortisol in the body. Consequently, the correct answer highlights that ketoconazole decreases the levels of these hormones, making it important in the context of conditions where excessive cortisol (such as Cushing's syndrome) or testosterone levels are problematic. Ketoconazole's role in inhibiting adrenal steroid synthesis is a significant aspect of its pharmacological profile and therapeutic applications. Its ability to lower cortisol production is particularly relevant for the treatment of certain endocrine disorders.
