Nifedipine 20 mg SR is a sustained-release formulation of nifedipine, a calcium channel blocker primarily used to manage hypertension (high blood pressure) and angina pectoris (chest pain). By inhibiting calcium influx into vascular smooth muscle and cardiac cells, it promotes vasodilation, reduces peripheral resistance, and improves blood flow. The sustained-release mechanism ensures a steady therapeutic effect over 24 hours, minimizing blood pressure fluctuations and reducing the frequency of dosing. Ideal for patients requiring long-term cardiovascular management, it helps maintain a healthy heart and vascular system.
