The name mineralocorticoid derives from early observations that these hormones were involved in the retention of sodium, a mineral.The primary endogenous mineralocorticoid is aldosterone, although a number of other endogenous hormones (including progesterone [1] and deoxycorticosterone) have mineralocorticoid function.
Adrenocortical hormones are divided into three classes by function: mineralocorticoids, glucocorticoids, and androgens. Mineralocorticoid hormones are synthesized in the outermost layer of the adrenal cortex known as the zona glomerulosa. [2] Their function is to regulate the concentration of electrolytes circulating in the blood. [1]
The receptor is activated by mineralocorticoids such as aldosterone and its precursor deoxycorticosterone as well as glucocorticoids like cortisol. In intact animals, the mineralocorticoid receptor is "protected" from glucocorticoids by co-localization of an enzyme, corticosteroid 11-beta-dehydrogenase isozyme 2 (a.k.a. 11β-hydroxysteroid ...
Drugs that interfere with the secretion or action of aldosterone are in use as antihypertensives, like lisinopril, which lowers blood pressure by blocking the angiotensin-converting enzyme (ACE), leading to lower aldosterone secretion. The net effect of these drugs is to reduce sodium and water retention but increase the retention of potassium.
Drugs and sexual desire is about sexual desire being manipulated through drugs from various approaches. Sexual desire is generated under the effects from sex hormones and microcircuits from brain regions. [1] Neurotransmitters play essential roles in stimulating and inhibiting the processes that lead to libido production in both men and women.
[49] [28] High dosages of testosterone but not low dosages of testosterone enhance the effects of low dosages of estrogens on sexual desire. [49] [28] Tibolone, a combined estrogen, progestin, and androgen, may increase sex drive to a greater extent than standard estrogen–progestogen therapy in postmenopausal women. [65] [66] [67] [68]
Adrenal insufficiency is a condition in which the adrenal glands do not produce adequate amounts of steroid hormones.The adrenal glands—also referred to as the adrenal cortex—normally secrete glucocorticoids (primarily cortisol), mineralocorticoids (primarily aldosterone), and androgens.
Mineralocorticoid receptor antagonists decrease the aldosterone effect by binding to the mineralocorticoid receptor inhibiting aldosterone. This leads to higher levels of potassium in serum and increased sodium excretion, resulting in decreased body fluid and lower blood pressure. [5]
