Cortone
cortisone
[kor´tĭ-sōn]a glucocorticoid with significant mineralocorticoid activity, isolated from the adrenal cortex, largely inactive in humans until it is converted to hydrocortisone (cortisol). Cortisone, as the acetate ester, is used as an antiinflammatory and immunosuppressant and for replacement therapy in adrenocortical insufficiency; administered orally or by intramuscular injection.

cortisone
(kōr'ti-sōn), Avoid using this word as a synonym of adrenocortical steroid.17-hydroxy-11-dehydrocorticosterone, a biologically inactive adrenal corticosteroid produced by the reversible 11-hydroxylation of cortisol (17-hydroxycorticosterone). It was the first glucocorticoid to be used in therapy (1949). Like the endogenous substance, natural and synthetic cortisone administered as a drug exerts no effect until converted to cortisol.

cortisone
The first corticosteroid produced for treatment purposes. It is converted to hydrocortisone in the liver. It was used to treat rheumatoid arthritis, severe allergies, adrenal failure and other conditions but has been largely replaced by more powerful synthetic steroids. A brand name is Cortisyl.Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005
cortisone
a GLUCOCORTICOID hormone secreted by the adrenal cortex, whose function is to combat stress. It causes shrinkage of lymph nodes and lowers the white blood cell count, reduces inflammation, promotes healing and stimulates GLUCONEOGENESIS. Cortisone controls its own production, which is triggered by the ADRENOCORTICOTROPIC HORMONE in a negative FEEDBACK MECHANISM.Collins Dictionary of Biology, 3rd ed. © W. G. Hale, V. A. Saunders, J. P. Margham 2005
Cortisone
