Answer

Ask about the use of medications that impair renal potassium excretion, as follows:

  • Potassium-sparing diuretics, which are especially popular in the treatment of cirrhosis and chronic heart failure
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) [58]
  • Angiotensin-converting enzyme (ACE) inhibitors
  • The combination of spironolactone and ACE inhibitors [59]
  • Angiotensin-receptor blockers (ARBs)
  • Direct renin inhibitors (eg, aliskiren)
  • Cyclosporine or tacrolimus
  • Antibiotics (eg, pentamidine and trimethoprim-sulfamethoxazole) [60]
  • Epsilon-aminocaproic acid (EACA) [27]
  • Oral contraceptive agents, such as drosperinone
