CORTONE

Cortisone is a man-made version of a natural hormone called cortisol (corticosteroid hormone). It is a naturally-occurring corticosteroid metabolite that is also used as a pharmaceutical prodrug. Cortisol is converted by the action of the enzyme corticosteroid 11-beta-dehydrogenase isozyme 2 into the inactive metabolite cortisone, particularly in the kidneys. This is done by oxidizing the alcohol group at carbon 11 (in the six-membered ring fused to the five-membered ring). Cortisone is converted back to the active steroid cortisol by stereospecific hydrogenation at carbon 11 by the enzyme 11β-Hydroxysteroid dehydrogenase type 1, particularly in the liver. Cortisol decreases your body’s natural defensive response and reduces symptoms such as swelling and allergic-type reactions. This medication is used to treat conditions such as arthritis, blood/hormone/immune system disorders, allergic reactions, certain skin and eye conditions, breathing problems, and certain cancers.
