moderate Known Drug Interaction
Use of potassium-sparing diuretics (spironolactone, triamterene, or amiloride), potassium supplements, or potassium-containing salt substitutes concomitantly with ACE inhibitors can increase the risk of hyperkalemia.
Midamor
Mavik
Amiloride is a water pill that helps your body hold onto potassium. It is often used with other water pills to prevent low potassium levels.
Trandolapril (Mavik) is a medicine that lowers blood pressure. It can also help people who have had a heart attack and have a weak heart.
Amiloride treats high blood pressure and heart failure. It helps restore normal potassium levels if you develop low potassium while taking other water pills. It can also prevent low potassium if you are at risk, such as if you take digoxin or have heart rhythm problems. Amiloride is not usually prescribed alone.
Trandolapril is used to treat high blood pressure. It can be used alone or with other blood pressure medicines. It is also used in people who have had a heart attack and have a weak heart (left ventricular dysfunction) or heart failure.
Amiloride blocks sodium channels in your kidneys. This action reduces the amount of potassium lost in your urine. This helps to maintain or increase potassium levels in your body.
Trandolapril belongs to a class of drugs called ACE inhibitors. It works by blocking a substance in your body that tightens blood vessels. This helps your blood vessels relax and lowers your blood pressure.

How to Read This amiloride vs trandolapril Comparison
amiloride is classified in the Potassium-Sparing Diuretic drug class, while trandolapril sits within the ACE Inhibitor class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, amiloride has 251 submissions while trandolapril has 560. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known moderate interaction flagged in FDA labeling, attributed to these drugs both prevent the body from removing potassium, which can cause potassium levels in your blood to become too high.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for amiloride or trandolapril.
