1. What Adalat LA is and what it is used foi
Adalat LA contains nifedipine, which belongs to a group of medicines called calcium antagonists.
Adalat LA is used to treat high blood pressure or angina (chest pain).
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.
2. What you need to know before you take Adalat LA
