Duactin (amlodipine besylate) is a calcium channel blocker that is used to treat hypertension and coronary artery disease. It is a long-acting medication that can be taken once daily.
Duactin works by relaxing the muscles of the blood vessels, which allows blood to flow more easily. This can help to lower blood pressure and reduce the risk of heart attack and stroke.
What is Duactin used for?
Duactin is a prescription medication used to treat high blood pressure (hypertension), chest pain (angina), and blocked arteries of the heart (coronary artery disease). It can be used by itself or with other medicines to treat these conditions.
- High blood pressure: Duactin helps to relax blood vessels and make it easier for blood to flow through them. This can lower blood pressure and reduce the risk of heart attack, stroke, and other health problems.
- Chest pain (angina): Duactin helps to improve blood flow to the heart muscle. This can relieve chest pain and prevent it from happening in the future.
- Blocked arteries of the heart (coronary artery disease): Duactin helps to prevent further narrowing of the arteries and improve blood flow to the heart. This can help to reduce the risk of heart attack.
It is important to take Duactin as prescribed by your doctor. Do not stop taking Duactin without talking to your doctor first. Stopping suddenly can increase your risk of high blood pressure or other health problems.
