These drugs include aminoglutethimide, ketoconazole, [151] and abiraterone acetate. [ 89 ] [ 31 ] [ 152 ] Aminoglutethimide inhibits cholesterol side-chain cleavage enzyme, also known as P450scc or CYP11A1, which is responsible for the conversion of cholesterol into pregnenolone and by extension the production of all steroid hormones, including ...
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 .
It is also a steroid that blocks the effects of the hormones aldosterone and, to a lesser degree, testosterone, causing some estrogen-like effects. [ 25 ] [ unreliable source? ] [ 26 ] [ 27 ] [ unreliable medical source? ] [ 4 ] [ 28 ] Spironolactone belongs to a class of medications known as potassium-sparing diuretics .
5α-Reductase inhibitors (5-ARIs), also known as dihydrotestosterone (DHT) blockers, are a class of medications with antiandrogenic effects which are used primarily in the treatment of enlarged prostate and scalp hair loss. They are also sometimes used to treat excess hair growth in women and as a component of hormone therapy for transgender ...
Aldosterone receptor antagonists, also known as mineralocorticoid receptor antagonist (MRA) can lower blood pressure by blocking the binding of aldosterone to the mineralocorticoid receptor. Spironolactone and eplerenone are MRAs that causes a block in the reabsorption of sodium, resulting in a decrease in blood pressure.
This is because they block the AR in the pituitary gland and hypothalamus and thereby inhibit the negative feedback of androgens on the hypothalamic–pituitary–gonadal axis (HPG axis). [120] This, in turn, results in increased gonadotropin secretion, activation of gonadal steroidogenesis, and an increase in the levels of estradiol (2.5-fold ...
These drugs inhibit the first and rate-limiting step of the renin–angiotensin–aldosterone system (RAAS), namely the conversion of angiotensinogen to angiotensin I. This leads to a totality in absence of angiotensin II based on the rationale that renin only acts to inhibit this step unlike Angiotensin Converting Enzyme which is also involved ...
