A hormone secreted by the adrenal cortex that regulates electrolyte and water balance by increasing the renal retention of sodium and the excretion of potassium.

Candesartan is an angiotensin-receptor blocker (ARB) that may be used alone or with other agents to treat hypertension. It is administered orally as the prodrug, candesartan cilexetil, which is rapidly converted to its active metabolite, candesartan, during a…

Canrenoic acid (as the salt potassium canrenoate) is an aldosterone antagonist. Like spironolactone, it is a prodrug, which is metabolized to canrenone in the body.

Captopril is a potent, competitive inhibitor of angiotensin-converting enzyme (ACE), the enzyme responsible for the conversion of angiotensin I (ATI) to angiotensin II (ATII). ATII regulates blood pressure and is a key component of the renin-angiotensin-aldos…

Enalapril is a prodrug belonging to the angiotensin-converting enzyme (ACE) inhibitor drug class that works on the renin-angiotensin-aldosterone system, which is responsible for the regulation of blood pressure and fluid and electrolyte homeostasis. Enalapril…

Eplerenone, an aldosterone receptor antagonist similar to spironolactone, has been shown to produce sustained increases in plasma renin and serum aldosterone, consistent with inhibition of the negative regulatory feedback of aldosterone on renin secretion. Th…

Fludrocortisone is a synthetic mineralocorticoid used in conjunction with [hydrocortisone] to replace missing endogenous corticosteroids in patients with adrenal insufficiency.[A187169,A187187] It is functionally similar to [aldosterone], the body's primary e…

Forasartan, a specific angiotensin II antagonist, is used alone or with other antihypertensive agents to treat hypertension. Forasartan competes with angiotensin II for binding at the AT1 receptor subtype. As angiotensin II is a vasoconstrictor which also sti…

Fosinopril is a phosphinic acid-containing ester prodrug that belongs to the angiotensin-converting enzyme (ACE) inhibitor class of medications. It is rapidly hydrolyzed to fosinoprilat, its principle active metabolite. Fosinoprilat inhibits ACE, the enzyme r…

Letrozole, or CGS 20267, is an oral non-steroidal type II aromatase inhibitor first described in the literature in 1990.[A190543,A1559,L11623,L11626] It is a third generation aromatase inhibitor like [exemestane] and [anastrozole], meaning it does not signifi…

Lisinopril is an angiotensin converting enzyme inhibitor (ACEI) used to treat hypertension, heart failure, and myocardial infarction.[L8384,L8387,L8390] Lisinopril and [captopril] are the only ACEIs that are not prodrugs.[A184853] It functions by inhibition o…

Olmesartan belongs to the angiotensin II receptor blocker (ARB) family of drugs, which also includes [telmisartan], [candesartan], [losartan], [valsartan], and [irbesartan]. ARBs selectively bind to angiotensin receptor 1 (AT1) and prevent the protein angiote…

Perindopril is a nonsulfhydryl prodrug that belongs to the angiotensin-converting enzyme (ACE) inhibitor class of medications. It is rapidly metabolized in the liver to perindoprilat, its active metabolite, following oral administration. Perindoprilat is a po…

Ramipril is a prodrug belonging to the angiotensin-converting enzyme (ACE) inhibitor class of medications. It is metabolized to ramiprilat in the liver and, to a lesser extent, kidneys. Ramiprilat is a potent, competitive inhibitor of ACE, the enzyme responsi…

Spironolactone is a potassium-sparing diuretic. It binds to mineralocorticoid receptors and functions as aldosterone antagonists.[A178192] It promotes sodium and water excretion and potassium retention.[A11837] Spironolactone was originally developed purely f…

Trandolapril is a non-sulhydryl prodrug that belongs to the angiotensin-converting enzyme (ACE) inhibitor class of medications. It is metabolized to its biologically active diacid form, trandolaprilat, in the liver. Trandolaprilat inhibits ACE, the enzyme res…

Valsartan belongs to the angiotensin II receptor blocker (ARB) family of drugs, which also includes [telmisartan], [candesartan], [losartan], [olmesartan], and [irbesartan]. ARBs selectively bind to angiotensin receptor 1 (AT1) and prevent the protein angiote…
