Nifedipine is one of a group of medicines called calcium channel blockers. These
capsules reduce the pain (angina pectoris) which occurs when the heart is starved of
oxygen, by improving oxygen supply to the heart muscle. Nifedipine also relaxes the
muscle lining of small blood vessels throughout the body and in this way brings high
blood pressure down to normal.
