Adalat LA contains nifedipine, which belongs to a group of medicines called calcium antagonists.
For high blood pressure: Adalat LA works by relaxing and expanding the blood vessels. This makes the blood flow more easily and lowers blood pressure. Lower blood pressure reduces the strain on your heart.
For angina: Adalat LA works by relaxing and expanding the arteries supplying the heart. This allows more blood and oxygen to reach the heart and decreases the strain on it. Your angina attacks will be less severe and less frequent if there is less strain on the heart.
* If you have had a heart attack within the last month.
* If you get a sudden angina attack. Adalat LA will not help relieve symptoms of angina quickly.
* If you have unstable angina.
