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 ]
The thiazides and potassium-sparing diuretics are considered to be calcium-sparing diuretics. [6] The thiazides cause a net decrease in calcium lost in urine. [7] The potassium-sparing diuretics cause a net increase in calcium lost in urine, but the increase is much smaller than the increase associated with other diuretic classes. [7] By ...
Hypokalemia which is recurrent or resistant to treatment may be amenable to a potassium-sparing diuretic, such as amiloride, triamterene, spironolactone, or eplerenone. Concomitant hypomagnesemia will inhibit potassium replacement, as magnesium is a cofactor for potassium uptake. [30]
For potassium-sparing diuretics, its common side effects include hyponatremia, hyperkalemia, metabolic acidosis and sexual dysfunction specifically for spironolactone. [ 4 ] [ 5 ] The use of diuretics should be avoided in patients with severe dehydration, anuria (absence of urine production). [ 4 ]
The tendency, as for all loop diuretics, to cause low serum potassium concentration (hypokalemia) has given rise to combination products, either with potassium or with the potassium-sparing diuretic amiloride (Co-amilofruse). Other electrolyte abnormalities that can result from furosemide use include hyponatremia, hypochloremia, hypomagnesemia ...
For potassium-sparing diuretics, such as amiloride and triamterene; both the drugs block epithelial sodium channels in the collecting tubules, thereby preventing potassium excretion into urine. [14] Spironolactone acts by competitively inhibiting the action of aldosterone. [13]
With the evidence, researchers created a comparative risk model and estimated that sugary drinks “cause more than 330,000 annual deaths from diabetes and cardiovascular disease,” Mozaffarian said.
Low potassium is caused by increased excretion of potassium, decreased consumption of potassium rich foods, movement of potassium into the cells, or certain endocrine diseases. [3] Excretion is the most common cause of hypokalemia and can be caused by diuretic use, metabolic acidosis , diabetic ketoacidosis , hyperaldosteronism , and renal ...
