Called also adrenocortical hormone and adrenocorticoid. All the hormones are steroids having similar chemical structures, but quite different physiologic effects.he corticosteroids synthesized by the adrenal glands include the glucocorticoids and the mineralocorticoids. The principal glucocorticoids are cortisol and corticosterone. The only physiologically important mineralocorticoid in humans is aldosterone. These hormones may be manufactured and administered exogenously.
Corticosteroid is a synthetic or naturally occurring 21-carbon steroid structure substances with four fused rings and vary functional branches attached to the ring system. Cholesterol and steroid hormones have this carbon skeleton.ts chemical designation is 17alpha,21-Dihydroxy-1,4-pregnadiene-3,11,20-trione. It is used in replacement therapy for adrenal insufficiency and as an anti-inflammatory and immunosuppressant in a wide variety of disorders and applied topically to the conjunctiva in the treatment of allergy and inflammation.
