There are several causes for this condition, including adrenal insufficiency, congenital adrenal hyperplasia, and some medications such as certain diuretics, NSAIDs, and ACE inhibitors. [3] Primary aldosterone deficiency; Primary adrenal insufficiency; Congenital adrenal hyperplasia (21 but not 11β and 17) Aldosterone synthase deficiency
Aldosterone synthase, also called steroid 18-hydroxylase, corticosterone 18-monooxygenase or P450C18, is a steroid hydroxylase cytochrome P450 enzyme involved in the biosynthesis of the mineralocorticoid aldosterone and other steroids. The enzyme catalyzes sequential hydroxylations of the steroid angular methyl group at C18 after initial 11β ...
In adrenal insufficiency, there is a deficiency in cortisol production which may be accompanied by a deficiency in aldosterone production (predominantly in primary adrenal insufficiency). [2] [3] Depending on the cause and type of adrenal insufficiency, the mechanism of the disease differs. Generally, the symptoms manifest through the systemic ...
Lorundrostat (developmental name MLS 101) is an aldosterone synthase inhibitor developed by Mineralys Therapeutics for high blood pressure. In clinical trials as an add-on medication for people with uncontrolled hypertension, decreased renin and elevated aldosterone it significantly reduced blood pressure. Hyperkalemia occurred in some trial ...
The genes encoding aldosterone synthase and 11β-hydroxylase are 95% identical and are close together on chromosome 8. In individuals with GRA, there is unequal crossing over so that the 5' regulatory region of the 11-hydroxylase gene is fused to the coding region of the aldosterone synthase. [citation needed]
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.

11β-Hydroxylase (CYP11B1) inhibitors such as amphenone B, [20] etomidate, [16] ketoconazole, [16] metyrapone, [16] mitotane, [16] and osilodrostat [25] inhibit the production of the potent corticosteroids cortisol, corticosterone, and aldosterone from the less potent corticosteroids 11-deoxycorticosterone and 11-deoxycortisol and are used in ...
