Metyrapone (CAT: I003995) is a medication used in the diagnosis and treatment of certain hormonal disorders. It works by inhibiting an enzyme called 11-beta-hydroxylase, which is involved in the production of cortisol, a hormone essential for various physiological functions. By inhibiting cortisol synthesis, metyrapone is used in diagnostic tests to assess adrenal gland function and to differentiate between different types of adrenal insufficiency. It can also be used as a treatment for Cushing’s syndrome, a condition characterized by excess cortisol production.
