An equianalgesic chart can be a useful tool, but the user must take care to correct for all relevant variables such as route of administration, cross tolerance, half-life and the bioavailability of a drug. [5] For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the ...

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 ...
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.
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 ...
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.
18-Hydroxy-11-deoxycorticosterone (also known as 18-OH-DOC, 18,21-dihydroxyprogesterone, and 18,21-dihydroxypregn-4-ene-3,20-dione) is an endogenous steroid and a mineralocorticoid. It is a hydroxylated metabolite of 11-deoxycorticosterone. [1] In rats, conversion of 11-deoxycorticosterone into 18-OH-DOC is catalyzed by the CYP11B3 enzyme. [2]
11-Deoxycortisol in mammals has limited glucocorticoid activity, but it is the direct precursor of the major mammalian glucocorticoid, cortisol. [15] As a result, the level of 11-deoxycortisol is measured to diagnose impaired cortisol synthesis, to find out the enzyme deficiency that causes impairment along the pathway to cortisol, and to differentiate adrenal disorders.
