Lovastatin is a medicine that helps lower cholesterol levels in your blood. It belongs to a class of drugs called statins.
Spironolactone is a medicine that helps remove extra fluid from your body and lower blood pressure. It also helps your heart work better if you have heart failure.
Lovastatin is used to lower cholesterol and reduce the risk of heart problems. It can help prevent heart attacks, unstable angina (chest pain), and the need for procedures to open blocked arteries. It's also used to slow down the hardening of arteries in people who already have heart disease. Lovastatin can also be used in children 10-17 years of age with high cholesterol due to genetic causes.
Spironolactone is used to treat heart failure by reducing fluid build-up and helping you live longer. It also treats high blood pressure, which can lower your chance of having a stroke or heart attack. This medicine can also manage fluid build-up caused by liver problems or a kidney problem called nephrotic syndrome. It can also treat a condition where your body makes too much of a hormone called aldosterone.
Lovastatin works by blocking a substance your body needs to make cholesterol. This helps to lower the amount of cholesterol in your blood. Lowering cholesterol helps to prevent heart disease and stroke.
Spironolactone belongs to a class of drugs called aldosterone antagonists. It works by blocking the effects of aldosterone, a hormone that causes your body to hold onto salt and water. By blocking aldosterone, spironolactone helps your body get rid of extra fluid and salt, which lowers blood pressure and reduces strain on the heart.
