Corticosteroids, also called adrenal cortex hormones, are steroids mainly produced by the adrenal cortex.
Classification
There are three major groups of corticosteroids.[1]
17-Ketosteroids
The 17-Ketosteroids are the sex steroids and are mainly produced in the zona reticularis layer (the innermost layer of the adrenal gland) of the adrenal cortex.
Glucocorticoids
Glucocorticoids affect carbohydrate metabolism and inflammation are mainly produced in the zona fasciculata of the adrenal cortex. The naturally occurring glucocorticoids include hydrocortisone (also called cortisol).[2] The normal adult secretes 10 to 20 mg of cortisol per day.[3]
Hydroxycorticosteroids
The hydroxycorticosteroids are mostly the mineralocorticoids and are mainly produced in the zona glomerulosa layer (the outermost layer of the adrenal gland) of the adrenal cortex.[4] The naturally occurring mineralocorticoids include aldosterone and deoxycorticosterone.
