Cortisone is a pregnene (21-carbon) steroid 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.
Hydrocortisone, or 17-hydroxycorticosterone, is under the class of glucocorticoids, which are steroids synthesized in the adrenal cortex of the kidneys. [ 30 ] [ 31 ] In order to illustrate its glucocorticoid activity, the A ring of hydrocortisone has a keto group in the 3rd carbon and a double bond between the 4th and 5th carbon. [ 32 ]
Aldosterone causes the tubules of the kidneys to retain sodium and water. This increases the volume of fluid in the body and drives up blood pressure. [citation needed] Steroid hormones are synthesized from cholesterol within the adrenal cortex. Aldosterone and corticosterone share the first part of their biosynthetic pathway.
Corticosteroids are a class of steroid hormones that are produced in the adrenal cortex of vertebrates, as well as the synthetic analogues of these hormones.Two main classes of corticosteroids, glucocorticoids and mineralocorticoids, are involved in a wide range of physiological processes, including stress response, immune response, and regulation of inflammation, carbohydrate metabolism ...
In humans and other animals, the adrenocortical hormones are hormones produced by the adrenal cortex, the outer region of the adrenal gland.These polycyclic steroid hormones have a variety of roles that are crucial for the body's response to stress (for example, the fight-or-flight response), and they also regulate other functions in the body.
Then change to oral hydrocortisone or cortisone as a single morning dose, and gradually decrease by 2.5 mg each week. When the morning dose is less than replacement, the return of normal basal adrenal function may be documented by checking 0800 cortisol levels prior to the morning dose; stop drugs when 0800 cortisol is 10 μg/dl.

Cortisone is another steroid that allows the glomeruli to filter the blood more efficiently. [1] This steroid also increases the urine volume as a result of its ability to decrease the retention of water within the kidney. [1] In people with healthy or hyperfunctioning adrenal glands, desoxycorticosterone plays a completely different role.
