Eplerenone may have a lower incidence than spironolactone of sexual side effects such as feminization, gynecomastia, impotence, low sex drive and reduction of size of male genitalia. [18] This is because other antimineralocorticoids have structural elements of the progesterone molecule, causing progestogenic and antiandrogenic outcomes. [ 4 ]
Eplerenone is a newer drug that was developed as a spironolactone analog with reduced adverse effects. In addition to the y-lactone ring and the substituent on C-7, eplerenone has a 9α,11α-epoxy group. This group is believed to be the reason why eplerenone has a 20-40-fold lower affinity for the mineralocorticoid receptor than spironolactone. [7]
[61] [62] [35] Levels of free testosterone were unchanged, however, suggesting that the antiandrogenic efficacy of spironolactone was due exclusively to direct AR blockade. [ 61 ] [ 62 ] In addition, other studies have found that 100 mg/day spironolactone is significantly or near-significantly inferior to 500 mg/day flutamide in improving ...
Spironolactone usually available in tablets, taken by mouth, though topical forms are also available. [4] Common side effects include electrolyte abnormalities, particularly high blood potassium, nausea, vomiting, headache, rashes, and a decreased desire for sex. [4] In those with liver or kidney problems, extra care should be taken. [4]
spironolactone eplerenone In the United States, the JNC8 (Eighth Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure) recommends thiazide-type diuretics to be one of the first-line drug treatments for hypertension, either as monotherapy or in combination with calcium channel blockers , ACEis ...
Spirolactones are a class of functional group in organic chemistry featuring a cyclic ester attached spiro to another ring system. The name is also used to refer to a class of synthetic steroids, called steroid-17α-spirolactones, 17α-spirolactosteroids, or simply 17α-spirolactones, which feature their spirolactone group at the C17α position.
There are a number of programs out there that, under the right conditions, will provide seniors with a free tablet. The Affordable Connectivity Program (ACP), for example, is overseen by the FCC ...
Potassium-sparing diuretics act to prevent sodium reabsorption in the collecting tubule by either binding ENaCs (amiloride, triamterene) or by inhibiting aldosterone receptors (spironolactone, eplerenone). This prevents excessive excretion of K + in urine and decreased retention of water, preventing hypokalemia. [10]
