moderate Known Drug Interaction
Potassium-sparing diuretics (spironolactone, amiloride, triamterene, and others) or potassium supplements can increase the risk of hyperkalemia.
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.
Ramipril is a medicine that lowers blood pressure. It can also help people with heart failure after a heart attack.
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.
Ramipril is used to treat high blood pressure. It can be used alone or with other blood pressure medicines. It is also used in patients who have signs of heart failure after a heart attack. Ramipril can lower the risk of death and hospitalization in these patients.
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.
Ramipril 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.
