Spironolactone, sold under the brand name Aldactone among others, is a diuretic medication primarily used to treat fluid build-up due to heart failure, liver scarring, or kidney disease. [4] It is also used in the treatment of high blood pressure , and low blood potassium that does not improve with supplementation , early puberty in boys, acne ...
Nephrotoxicity is toxicity in the kidneys. It is a poisonous effect of some substances, both toxic chemicals and medications, on kidney function. [1] There are various forms, [2] and some drugs may affect kidney function in more than one way. Nephrotoxins are substances displaying nephrotoxicity.
Symptoms occur when a kidney stone is big enough to cause an irritation or blockage. Here’s how to know that you might need treatment for kidney stones: Severe pain on either side of your lower back
Renal tubular acidosis (RTA) is a medical condition that involves an accumulation of acid in the body due to a failure of the kidneys to appropriately acidify the urine. [1] In renal physiology, when blood is filtered by the kidney, the filtrate passes through the tubules of the nephron, allowing for exchange of salts, acid equivalents, and other solutes before it drains into the bladder as urine.
The symptoms and sequelae of dRTA are variable and range from being completely asymptomatic, to loin pain and hematuria from kidney stones, to failure to thrive and severe rickets in childhood forms as well as possible renal failure and even death. [citation needed]
Kidney stones are primarily composed of calcium salts, with the most common being calcium oxalate (70-80%), followed by calcium phosphate and uric acid. When urine contains high concentrations of these ions, they can form crystals and eventually stones. [41] The formation of kidney stones occurs in three main phases: [41]
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.
Secondary hyperaldosteronism (also hyperreninism, or hyperreninemic hyperaldosteronism) is due to overactivity of the renin–angiotensin–aldosterone system (RAAS).. The causes of secondary hyperaldosteronism are accessory renal veins, fibromuscular dysplasia, reninoma, renal tubular acidosis, nutcracker syndrome, ectopic tumors, massive ascites, left ventricular failure, and cor pulmonale.
