Chemical name: (11beta) -9-Fluoro-11,17,21-trihydroxypregn-4-en-3,20-dione (and in the form of 21-acetate)

Pharmacology: Pharmacological action - mineralocorticoid, glucocorticoid.
Increases blood pressure, reabsorption of sodium, water and potassium secretion in the renal tubules. It inhibits the production of ACTH, adrenal gland function, stimulates gluconeogenesis, protein breakdown (causes a negative nitrogen balance), shows immunosuppressive and anti-inflammatory activity; topical application reduces itching and exudation. It is well absorbed from the digestive tract. Easily passes histohematological barriers. T 1/2 - 18-36 hours. Excreted in the urine in the form of metabolites. A small part is excreted by lactating mammary glands.

Application: Primary and secondary adrenal insufficiency, adrenogenital syndrome with severe loss of electrolytes; locally in ophthalmic practice: keratitis, allergic diseases and eye injuries.
