Glucocorticoids are a class of corticosteroids, which are a type of steroid hormone. They are produced in the adrenal cortex and are involved in a wide range of physiological processes, including the stress response, immune response, regulation of inflammation, carbohydrate metabolism, protein catabolism, and blood electrolyte levels. Some commonly known glucocorticoids include cortisol and synthetic variants like prednisone and dexamethasone.
