What Adalat capsules are and what
they are used for

Adalat capsules contain nifedipine, which belongs to a group of medicines
called calcium antagonists.
Adalat capsules are used to treat high blood pressure, angina (chest
pain) or a condition called Raynaud’s phenomenon which causes
discolouration (often whitening) of the fingers and toes.
For high blood pressure: Adalat capsules work 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 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.
