What Adalat LA is and what it is used for

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.

What you need to know before you take Adalat LA

* 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.

with an opening through the abdominal wall) in your gut.
