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 ...
Glucocorticoid potency, duration of effect, and the overlapping mineralocorticoid potency vary. Cortisol is the standard of comparison for glucocorticoid potency. Hydrocortisone is the name used for pharmaceutical preparations of cortisol. [citation needed] The data below refer to oral administration.
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 ...
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.
Even low-potency topical glucocorticoids are able to cause adverse effects in children when used for prolonged periods of time. Generally, a smaller dose of topical glucocorticoid is required by children for a given condition than adults, as children have relatively smaller body surface area compared to adults.
Some recommend using the topical steroid for 3 consecutive days on, followed by 4 consecutive days off. [10] Long-term use of topical steroids can lead to secondary infection with fungus or bacteria (see tinea incognito ), skin atrophy, telangiectasia (prominent blood vessels), skin bruising and fragility.
The steroid hormones are referred to by various abbreviations in the biological literature. The purpose of this list is to give commonly used abbreviations for steroid hormones, with supporting references to the literature.
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.
