| drug–drug interactions | Enalapril + spironolactone | ACEIs and potassium- sparing diuretics | 6 (2.9) | Avoid routinely using a RAS inhibitor and potassium-sparing diuretic, concurrently in those with chronic kidney disease Stage 3a or higher | 
| Medications whose dosages should be adjusted based on renal function | Spironolactone | Potassium-sparing diuretics | 3 (1.4) | Avoid when CrCl <30 mL/min | 
| Total PIMs | 210 (100) | 
ACEI = angiotensin-converting enzyme inhibitor; CrCl = creatinine clearance; RAS = renin-angiotensin system; VTE = venous thromboembolism.
