Nifedipine

Uses of Nifedipine

Nifedipine is a calcium channel blocker that works by relaxing blood vessels and reducing the heart’s workload.

Is primarily used for:

• High Blood Pressure (Hypertension) – Helps relax blood vessels, making it easier for the heart to pump blood.
• Angina (Chest Pain) – Improves blood flow to the heart by dilating coronary arteries, reducing the risk of chest pain.
• Raynaud’s Phenomenon – Relieves symptoms by improving blood circulation to the fingers and toes.
