Mineralocorticoids are a class of corticosteroids, which in turn are a class of steroid hormones. Mineralocorticoids are produced in the adrenal cortex and influence salt and water balances (electrolyte balance and fluid balance). The primary mineralocorticoid is aldosterone.
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 ...
A mineralocorticoid receptor antagonist (MRA or MCRA) [1] or aldosterone antagonist, is a diuretic drug which antagonizes the action of aldosterone at mineralocorticoid receptors. This group of drugs is often used as adjunctive therapy, in combination with other drugs, for the management of chronic heart failure .
Cortisone = 17α,21-dihydroxypregn-4-ene-3,11,20-trione; Pregnenolone = pregn-5-en-3β-ol-20-one; Progesterone = pregn-4-ene-3,20-dione; The glucocorticoid activity of progesterone and 17α-hydroxyprogesterone is very weak (>100-fold less than that of cortisol). [1] The above list includes precursors and intermediates in corticosteroid ...
Glucocorticoids are distinguished from mineralocorticoids and sex steroids by their specific receptors, target cells, and effects. In technical terms, "corticosteroid" refers to both glucocorticoids and mineralocorticoids (as both are mimics of hormones produced by the adrenal cortex), but is often
Adrenal steroids such as glucocorticoids and mineralocorticoids are commonly used as treatments in diseases such as Congenital adrenal hyperplasia. [2] CAH commonly causes overproduction of androgens, glucocorticoid treatment is used to reduce Adrenocorticotropic hormone (ACTH) and reduce the production of androgens allowing for symptoms of CAH to be managed though treatment is required to be ...
Chemically, methylprednisolone is a synthetic pregnane steroid hormone derived from hydrocortisone and prednisolone. It belongs to a class of synthetic glucocorticoids and more generally, corticosteroids. It acts as a mineralocorticoid and glucocorticoid receptor agonist.
Fludrocortisone is a corticosteroid and acts as a powerful mineralocorticoid, along with some additional but comparatively very weak glucocorticoid activity. [12] Relative to cortisol, it is said to have 10 times the glucocorticoid potency but 250 to 800 times the mineralocorticoid potency.
