Product Description
Nifedipine 5mg capsules are a type of medication used to treat high blood pressure (hypertension) and chest pain (angina). It belongs to a class of drugs called calcium channel blockers. Nifedipine works by relaxing blood vessels, allowing blood to flow more easily and lowering blood pressure. This helps to reduce the workload on the heart and prevent angina attacks.
How Nifedipine Works:
Nifedipine works by blocking the entry of calcium into the muscle cells of the arteries. Calcium is essential for muscle contraction. By blocking calcium, nifedipine relaxes the muscles of the arteries, causing them to widen. This widening of the arteries reduces resistance to blood flow, lowering blood pressure and improving blood supply to the heart.
