Spironolactone can also have numerous other interactions, most commonly with other cardiac and blood pressure medications, for instance digoxin. [8] Licorice, which has indirect mineralocorticoid activity by inhibiting mineralocorticoid metabolism, has been found to inhibit the antimineralocorticoid effects of spironolactone.
Aldosterone binds to aldosterone receptors (mineralocorticoid receptors) increasing sodium reabsorption in an effort to increase blood pressure and improve fluid status in the body. When excessive sodium reabsorption occurs, there is an increasing loss of K + in the urine and can lead to clinically significant decreases, termed hypokalemia ...
Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke, heart failure, kidney failure and myocardial infarction. Evidence suggests that a reduction of blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21%.
However, spironolactone is metabolized to three active metabolites, which give it prolonged activity (13.8 – 16. 5 hours). Spironolactone has a long half-life and is excreted 47-51% through kidneys. Patients with chronic kidney disease therefore require close monitoring when taking the drug. Spironolactone is also eliminated through feces (35-41%
Loop diuretics may also precipitate kidney failure in patients concurrently taking an NSAID and an ACE inhibitor—the so-called "triple whammy" effect. [ 19 ] Because furosemide, torsemide and bumetanide are technically sulfa drugs, there is a theoretical risk that patients sensitive to sulfonamides may be sensitive to these loop diuretics.
Spironolactone inhibits the effects of mineralocorticoids, namely, aldosterone, by displacing them from the mineralocorticoid receptor (MR) in the cortical collecting duct of kidney nephrons. This decreases the reabsorption of sodium and water while limiting the excretion of potassium.
Diuretics (furosemide, spironolactone etc) When congestive heart failure starts, diuretics encourage the kidneys to get rid of excess fluid, reducing the blood pressure and the amount of fluid ...
Volume of blood plasma delivered to the kidney per unit time. PAH clearance is a renal analysis method used to provide an estimate. Approximately 625 ml/min. renal blood flow = (HCT is hematocrit) Volume of blood delivered to the kidney per unit time. In humans, the kidneys together receive roughly 20% of cardiac output, amounting to 1 L/min in ...
