Applies to: Aldactone (spironolactone) and lisinopril

MONITOR CLOSELY: Concomitant use of angiotensin converting enzyme (ACE) inhibitors and potassium-sparing diuretics may increase the risk of hyperkalemia. Inhibition of ACE results in decreased aldosterone secretion, which can lead to increases in serum potassium that may be additive with that induced by potassium-sparing diuretics. The interaction may be mild in most patients with normal renal function. In a retrospective review of 127 patients treated with captopril, some of whom also received a potassium-sparing diuretic or a diuretic with a potassium supplement, no association was found between captopril use and changes in serum potassium levels. In another retrospective study, enalapril was shown to have no effect on the serum potassium of 16 patients who were taking furosemide or amiloride, and there was no difference in serum potassium levels of the group taking enalapril with diuretics compared to a similar group not taking enalapril. However, life-threatening and fatal hyperkalemia have been reported to occur within days to weeks of receiving the combination in patients with risk factors such as renal impairment, diabetes, old age, severe or worsening heart failure, and concomitant use of potassium supplements or other medications that increase serum potassium. Both ACE inhibitors alone and diuretics alone have been associated with hyperkalemia in patients with renal impairment. ACE inhibitors may also cause deterioration of renal function in patients with chronic heart failure, and the risk is increased if they are sodium-depleted or dehydrated after excessive diuresis.

MANAGEMENT: Caution is advised if ACE inhibitors are used with potassium-sparing diuretics, particularly in patients with renal impairment, diabetes, old age, worsening heart failure, and/or a risk for dehydration. Serum potassium and renal function should be checked regularly, and potassium supplementation should generally be avoided unless it is closely monitored. Patients should be given dietary counseling and advised to seek medical attention if they experience signs and symptoms of hyperkalemia such as weakness, listlessness, confusion, tingling of the extremities, and irregular heartbeat. If spironolactone is prescribed with an ACE inhibitor, some investigators recommend that its dosage not exceed 25 mg/day.

Drug and food interactions

Moderate

lisinopril food

Applies to: lisinopril

GENERALLY AVOID: Moderate-to-high dietary intake of potassium can cause hyperkalemia in some patients who are using angiotensin converting enzyme (ACE) inhibitors. In some cases, affected patients were using a potassium-rich salt substitute. ACE inhibitors can promote hyperkalemia through inhibition of the renin-aldosterone-angiotensin (RAA) system.

MANAGEMENT: It is recommended that patients who are taking ACE inhibitors be advised to avoid moderately high or high potassium dietary intake. Particular attention should be paid to the potassium content of salt substitutes.

spironolactone food

Applies to: Aldactone (spironolactone)

MONITOR: Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation. Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.

MANAGEMENT: Caution and close monitoring for development of hypotension is advised during coadministration of these agents. Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
