1. What Cardilate MR is and what it is used for
Your tablets are called Cardilate MR Tablets. The common name for your tablets is nifedipine.
They are part of a group of drugs known as calcium channel blockers which interfere with the
movement of calcium in heart muscle cells.
Cardilate MR Tablets are used to treat high blood pressure (hypertension) and to prevent the
condition called angina pectoris (pain in the centre of your chest which is brought on by
For high blood pressure: Cardilate MR 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: Cardilate MR 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 Cardilate MR

Do not take Cardilate MR Tablets if you:
• If you have had a heart attack within the last month.
• If you get a sudden angina attack. Cardilate MR will not help relieve symptoms of
angina quickly.

dihydropyridines) or any of the other ingredients of this medicine (listed in section 6).
• If you are taking rifampicin, an antibiotic.
• If you have been told that you have a narrowing of the aortic heart valve
• If you have ever had a collapse caused by a heart problem (cardiogenic shock),
during which you became breathless, pale and had a cold sweat and dry mouth.
• If your blood pressure continues to rise despite treatment (malignant hypertension).
• If you have a “Kock pouch” (a surgically constructed intestinal reservoir with an opening
through the abdominal wall) in your gut.
 Tell your doctor and do not take Cardilate MR if any of these apply to you.
