HOW DO STEROIDOGENESIS INHIBITORS WORK?

Steroidogenesis inhibitors are a class of drugs used to treat Cushing’s disease in adult patients ineligible for or who had a failed pituitary surgery.

Cushing’s disease is a metabolic disorder caused by the overproduction of corticosteroid (cortisol-a stress hormone) hormones by the adrenal cortex (a small organ on top of each kidney) and often involves obesity and high blood pressure. Cortisol helps maintain blood sugar levels, protects the body from physical stress, and suppresses inflammation. Many a time, Cushing’s disease is the result of adrenocorticotropic hormone hypersecretion secondary to a pituitary tumor. Patients with Cushing’s disease suffer from various comorbidities that increase the risk of mortality, and the disease is characterized by signs and symptoms such as:

Steroidogenesis inhibitors possess anti-adrenal activity, which works by binding to and inhibiting the activity of 11-beta-hydroxylase, the enzyme that catalyzes the final step of cortisol synthesis. The inhibition of 11-beta-hydroxylase prevents the production of excess cortisol, thereby decreasing and normalizing the levels of cortisol.

Steroidogenesis inhibitors are administered via oral route, typically twice daily with or without food.

Steroidogenesis inhibitors work by decreasing the cortisol overproduction in the body by blocking the enzyme known as "11-beta-hydroxylase" (enzyme that catalyzes the final step in the biosynthesis of endogenous cortisol) and thus maintaining a normal cortisol level.

HOW ARE STEROIDOGENESIS INHIBITORS USED?

Steroidogenesis inhibitors are indicated for Cushing’s disease in adults for whom pituitary surgery is not an option or has not been a curative treatment.
