Spironolactone Disease Interactions

There are 6 disease interactions with spironolactone:

Potassium-Sparing Diuretics (Includes Spironolactone) ↔ Acidosis

Severe Potential Hazard, High plausibility

Applies to: Diabetes Mellitus, Acidosis, Pulmonary Impairment, Sleep Apnea

Acidosis alters the ratio of extracellular to intracellular potassium and may commonly lead to rapid increases in serum potassium levels. Conversely, high serum potassium concentrations may potentiate acidosis. Because of their hyperkalemic effects, therapy with potassium-sparing diuretics should be avoided in patients with metabolic or respiratory acidosis. These agents should be used cautiously in patients in whom acidosis may occur, such as patients with cardiopulmonary disease, severe respiratory disease, or poorly controlled diabetes. Acid-base balance and serum potassium levels should be monitored at regular intervals.

Potassium-Sparing Diuretics (Includes Spironolactone) ↔ Diabetes

Severe Potential Hazard, High plausibility

Applies to: Diabetes Mellitus

Potassium-sparing diuretics can cause hyperkalemia, which may result in life-threatening cardiac arrhythmias. Patients with diabetes mellitus, with or without nephropathy, may be particularly susceptible to the hyperkalemic effect of these drugs due to a defect in the renin-angiotensin-aldosterone axis. Therapy with potassium-sparing diuretics should be avoided, if possible, in patients with diabetes, especially uncontrolled or insulin-dependent diabetes mellitus. If these drugs are used, serum potassium levels and renal function should be monitored at regular intervals. Determination of serum electrolytes is especially important during initiation of therapy, after a dosage adjustment, and during illness that could alter renal function.

Potassium-Sparing Diuretics (Includes Spironolactone) ↔ Electrolytes/Fluid

Severe Potential Hazard, High plausibility

Applies to: Electrolyte Abnormalities, Hyponatremia

All diuretics may cause or aggravate fluid and electrolyte disturbances. Potassium-sparing diuretics may cause hyperkalemia and, infrequently, hyponatremia. The latter generally occurs when these agents are combined with other diuretics such as thiazides or used in markedly edematous patients with restricted sodium intake. Therapy with potassium-sparing diuretics should be administered cautiously in patients with or predisposed to electrolyte abnormalities. Electrolyte imbalances should be corrected prior to initiating therapy, and serum electrolyte concentrations should be monitored periodically and maintained at normal ranges during therapy. Determination of serum electrolytes is especially important during initiation of therapy, after a dosage adjustment, and during illness that could alter renal function.

Potassium-Sparing Diuretics (Includes Spironolactone) ↔ Hyperkalemia

Severe Potential Hazard, High plausibility

Applies to: Hyperkalemia

The use of potassium-sparing diuretics is contraindicated in the presence of elevated serum potassium concentrations (> 5.5 mEq/L). Potassium-sparing diuretics can cause hyperkalemia, which may result in life-threatening cardiac arrhythmias. Careful monitoring of serum potassium levels is necessary in all patients treated with potassium-sparing diuretics, especially during initiation of therapy, after dosage adjustment, and during illness that could alter renal function. The diuretic should be withdrawn immediately if hyperkalemia develops, and measures should be initiated to lower serum potassium if it exceeds 6.5 mEq/L. The combined use of a potassium-sparing diuretic with a kaliuretic diuretic (e.g., thiazides) may decrease the risk of hyperkalemia.

Potassium-Sparing Diuretics (Includes Spironolactone) ↔ Liver Disease

Severe Potential Hazard, Moderate plausibility

Applies to: Liver Disease

Rapid alterations in fluid and electrolyte balance may precipitate hepatic coma in patients with liver disease. Hepatic encephalopathy has been associated with the use of diuretics, most frequently thiazides but also some potassium-sparing diuretics. Therapy with all diuretics should be administered cautiously in patients with severely impaired hepatic function. These patients should be monitored carefully for signs and symptoms of hepatic encephalopathy such as tremors, confusion, increased jaundice, and coma. Since spironolactone and triamterene are primarily metabolized by the liver, reduced dosages of these drugs may also be necessary in severe hepatic impairment.

Potassium-Sparing Diuretics (Includes Spironolactone) ↔ Renal Dysfunction

Severe Potential Hazard, High plausibility

Applies to: Renal Dysfunction

The use of potassium-sparing diuretics is contraindicated in patients with anuria, acute or progressive renal insufficiency, or diabetic nephropathy. Potassium-sparing diuretics can cause hyperkalemia, which may result in life-threatening cardiac arrhythmias. Patients with impaired renal function may be particularly susceptible to the hyperkalemic effect of these drugs. Therapy with potassium-sparing diuretics should be administered cautiously in patients with evidence of renal function impairment (BUN > 30 mg/dL or serum creatinine > 1.5 mg/dL). If these drugs are used, serum potassium levels and renal function should be monitored at regular intervals. Determination of serum electrolytes is especially important during initiation of therapy, after a dosage adjustment, and during illness that could alter renal function.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.

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.
