Hyperkalemia potassium sparing diuretics causing

Hypertension is a common occurrence with tacrolimus and may require treatment with antihypertensive agents. Since tacrolimus may cause hyperkalemia, potassium-sparing diuretics should be avoided... 

The hypotensive effects of most antihypertensive dru are increased when administered with diuretics and other antihypertensives. Many dnigp can interact with the antihypertensive drugs and decrease their effectiveness (eg, antidepressants, monoamine oxidase inhibitors, antihistamines, and sympathomimetic bronchodilators). When the ACE inhibitors are administered with the NSAIDs, their antihypertensive effect may be decreased. Absorption of the ACE inhibitors may be decreased when administered with the antacids. Administration of potassium-sparing diuretics or potassium supplements concurrently with the ACE inhibitors may cause hyperkalemia. When the angiotensin II receptor agonists are administered with... 

Potassium-sparing diuretics may cause hyperkalemia, especially in patients with chronic kidney disease or diabetes, and in patients receiving concurrent treatment with an ACE inhibitor, ARB, NSAID, or potassium supplement. Eplerenone has an increased risk for hyperkalemia and is contraindicated in patients with impaired renal function or type 2 diabetes with proteinuria. Spironolactone may cause gynecomastia in up to 10% of patients, but this effect occurs rarely with eplerenone.

Potassium-sparing diuretics (e.g., spironolactone, amiloride, triamterene) may cause a dangerous build-up of excessive potassium in the body. Signs of hyperkalemia, or excess potassium, include ... 

Alterations in the serum potassium level are hazardous because they may result in cardiac arrhythmias. Drugs that may cause hyperkalemia despite normal renal function include potassium itself, -blockers, digitalis glycosides, potassium-sparing diuretics, and fluoride. Drugs associated with hypokalemia include barium, B-agonists, caffeine, theophylline, and thiazide and loop diuretics. 

As a potassium-sparing diuretic, amiloride can cause hyperkalemia (3), even in patients who are taking a potassium-wasting diuretic (4). This effect can be enhanced by concomitant therapy with ACE inhibitors or angioten-sin-II receptor antagonists. In five patients with diabetes melUtus over 50 years of age who were taking an ACE inhibitor the serum potassium rose markedly 8-18 days after the addition of amiloride (5). AH but one had some degree of renal impairment In four cases potassium concentrations were between 9.4 and 11 mmol/1. 

Co-administration of potassium-sparing diuretics with ACE inhibitors can cause severe hyperkalemia (SED-14, 674). In a retrospective study, five patients developed extreme hyperkalemia (9.4-11 mmol/1) within 8-18 days of starting combination therapy with co-amilozide (amiloride -I- hydrochlorothiazide) and an ACE inhibitor (5). 

Pentamidine is structurally similar to amiloride and can cause severe hyperkalemia if co-prescribed with potassium-sparing diuretics (10). This is a particularly important interaction in patients with AIDS. 

ACE inhibitors can cause hyperkalemia because they inhibit the release of aldosterone. The effect is usually not significant in patients with normal renal function. However, in patients with impaired kidney function and/or in patients taking potassium supplements (including salt substitutes) or potassium-sparing diuretics, and especially aldosterone antagonists, hyperkalemia can occur. In two cases, hypoaldosteronism with diabetes was implicated (53,54). 

Co-administration of potassium-sparing diuretics with ACE inhibitors can cause severe hyperkalemia (SED-14,674). 

In addition to CKD as a risk factor, other contributing factors should also be considered. This includes exposure to potassium-sparing diuretics -blockers, which work predominantly via 82-antagonistic effects to interfere with the extrarenal translocation of potassium into cells and ACEls, which may cause hyperkalemia by reducing aldosterone production. Polycitra, used for the treatment of metabolic acidosis, contains potassium citrate and should not be prescribed for patients with severe CKD. If hyperkalemia develops, management options are based on the degree to which potassium is elevated (see Chap. 50). 

The adverse effects of ACE inhibitors are excessive hypotension associated with volume or salt depletion. All ACE inhibitors commonly cause a dry cough and rarely may cause angioedema. Renal failure can occur in patients with bilateral renal artery stenosis. Hyperkalemia may occur in patients with renal insufficiency, diabetics with even mild renal impairment, and patients taking potassium supplements or potassium-sparing diuretics. ACE inhibitors are fetotoxic and are not recommended for use during pregnancy. 

The potassium-sparing diuretics should not be used concurrently with potassium supplanents, as this combination is likely to produce hyperkalemia. Poor renal function also heightens the risk of hyperkalemia G1 disturbances, rash, drowsiness, or dizziness are aU associated with their use. Spironolactone can cause the blood urea nitrogen level to uiCTease and lead to menstrual irregularities (see also Table 25). 

Diuretics Group toxicity agents may cause hypokalemia, hyperkalemia, hyperuricemia, hyperglycemia, and hypomagnesemia may increase serum cholesterol use of potassium-sparing agents is recommended ... 

Answer D. Drugs that decrease extracellular potassium such as the thiazide and loop diuretics and adrenal glucocorticoids will lead to an increased requirement for insulin by making it more difficult to release the hormone from the B cells of the pancreas. Spironolactone is K sparing, tends to cause hyperkalemia, and does not interfere with the release of insulin. Stress conditions such as examinations also increase insulin requirement.
