Uses of Nifedipine Retard 20mg
Nifedipine Retard 20mg is used to treat high blood pressure (hypertension) by lowering blood pressure and reducing the risk of cardiovascular complications. It alleviates chest pain (angina) by improving blood flow to the heart muscle and reducing its oxygen demand. It may also be used to manage Raynaud’s phenomenon, a condition characterized by reduced blood flow to the extremities.
How Does Nifedipine Retard 20mg Work?
Nifedipine is a calcium channel blocker that inhibits the movement of calcium ions into smooth muscle cells of blood vessels and the heart. This action relaxes and dilates blood vessels, improving blood flow and reducing blood pressure. It also decreases the oxygen demand of the heart, alleviating symptoms of angina.
