Introduction to Nicardia Retard 20mg Tablet
Nicardia Retard 20mg Tablet is an antihypertensive agent with an active ingredient called Nifedipine which belongs to the medication class known as calcium channel blockers. This drug is commonly used to treat hypertension (raised blood pressure) and certain types of angina (chest pain) caused by coronary artery disease. In hypertension conditions, this medicine relaxes the blood vessels and makes the blood pass smoothly. In angina, it improves the blood supply, which prevents chest pain.
