 (the accumulation of excess fluids in the tissues of the body), which is often the result of underlying disease of the kidneys, liver, lungs, or heart (e.g., congestive heart failurecongestive heart failure,
inability of the heart to expel sufficient blood to keep pace with the metabolic demands of the body. In the healthy individual the heart can tolerate large increases of workload for a considerable length of time.

The 7-year case-control study involved all Ontario residents aged 66 years or older who were admitted to the hospital during 1994-2000 because of drug toxicity and who had been treated in the previous week with glyburide plus co-trimoxazole, digoxin plus clarithromycin, or an angiotensin-converting enzyme (ACE) inhibitor plus potassium-sparing diuretics.
One of these transiently hypokalemic patients was also taking triamterene, a potassium-sparing diuretic.
Among the approaches to treat diuretic-induced hypokalemia are the effervescent, liquid, or enteric-coated slow-release potassium preparations, the so-called potassium-sparing diuretics, and the high-potassium diet.
For heart failure patients, using potassium-sparing diuretics, rather than other diuretics, cuts the risk of death from, or hospitalization for, progressive heart failure and cardiovascular disease, reported Dr.
Diuretics are divided into three subclasses: thiazide diuretics, loop diuretics, and potassium-sparing diuretics.
The latter effects are also achievable using potassium-sparing diuretics, which in Dr.
Among the three subclasses of diuretics, potassium-sparing diuretics produce the most modest diuresis.
The study authors suggested that the beneficial effect on urinary excretion could be similar to action of potassium-sparing diuretics due to unchanged potassium levels in the Se-SM group.
The classes of drugs used to treat hypertension are angiotensin-converting-enzyme inhibitors (ACEIs), angiotensin 1I receptor antagonists (ARBs), direct renin antagonists, calcium channel blockers (CCBs), alpha-1 blockers, direct vasodilators, diuretics, beta-blockers (BBs), potassium-sparing diuretics, aldosterone receptor blockers and centrally acting alpha-2 antagonists.
Also at risk is anyone on a medication that causes the body to hold onto potassium, including potassium-sparing diuretics like Dyazide and Spirozide, ACE inhibitors like Lotensin and Vasotec, angiotensin-receptor blockers such as Tevetan and Avapro and daily doses of nonsteroidal anti-inflammatory drugs like aspirin and ibuprofen.
Types of diuretics include thiazides, such as Diuril (chlorothiazide) and Esidrex (hydrochlorothiazide); potassium-sparing diuretics, such as Aldactone (spironolactone); and loop diuretics, such as Lasix (furosemide).
