Eplerenone, sold under the brand name Inspra, is an aldosterone antagonist type of potassium-sparing diuretic that is used to treat chronic heart failure and high blood pressure, particularly for people with resistant hypertension due to elevated aldosterone.
Eplerenone, a steroidal antimineralocorticoid of the spirolactone group Estriol triacetate , an estrogen medication and an estrogen ester Index of chemical compounds with the same molecular formula
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]
Structural formula of the potassium-sparing diuretics. Click to enlarge. Potassium-sparing diuretics or antikaliuretics [1] refer to drugs that cause diuresis without causing potassium loss in the urine. [2] They are typically used as an adjunct in management of hypertension, cirrhosis, and congestive heart failure. [3]
A newer medication, eplerenone, has been approved by the US Food and Drug Administration (FDA) for the treatment of heart failure, and lacks the antiandrogenic effects of spironolactone. As such, it is far more suitable for men for whom long-term medication is being chosen.
Finerenone, marketed under the brand name Kerendia among others, is a medication used to reduce the risk of kidney function decline, kidney failure, cardiovascular death, non-fatal heart attacks, and hospitalization for heart failure in adults with chronic kidney disease associated with type 2 diabetes.

Chemical chaperones are a broad and diverse group of molecules, and they can influence protein stability and polypeptide organization through a variety of mechanisms. Chemical chaperones are used for a range of applications, from production of recombinant proteins to treatment of protein misfolding in vivo.
Triamterene directly blocks the epithelial sodium channel [4] (ENaC) on the lumen side of the kidney collecting tubule. [5]: 127 Other diuretics cause a decrease in the sodium concentration of the forming urine due to the entry of sodium into the cell via the ENaC, and the concomitant exit of potassium from the principal cell into the forming urine.
