What Adalat capsules are

For angina: Adalat capsules work 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.
Adalat capsules can increase the risk of serious heart problems in patients
with high blood pressure or angina. Because of this, Adalat capsules are
only used in these patients if no other treatments are appropriate.
For Raynaud’s phenomenon: Adalat capsules work by relaxing and
expanding the blood vessels in the fingers and toes. This helps ensure a
good blood supply.
