Norvasc is a prescription medication containing amlodipine besylate, a calcium channel blocker used to treat high blood pressure and certain types of chest pain. It belongs to the dihydropyridine class and acts primarily by relaxing blood vessels. Norvasc is approved for hypertension in adults and children aged six years and older, as well as selected forms of angina and coronary artery disease in adults. It is taken orally, typically once daily.
read more about norvasc ...Norvasc blocks calcium entry into vascular smooth muscle cells through calcium channels. This causes arteries to relax and widen, reducing resistance to blood flow and lowering blood pressure. Amlodipine also relaxes coronary arteries and can improve blood flow to the heart muscle. By reducing vascular resistance, it decreases the heart's workload. Its long duration of action supports once-daily dosing and sustained blood pressure management.
Norvasc is prescribed for hypertension, chronic stable angina, and vasospastic angina. It is also approved for certain patients with documented coronary artery disease to reduce the risk of hospitalization for angina or coronary revascularization. Lowering high blood pressure reduces the risk of cardiovascular complications, including stroke and heart attack. In children aged six through 17 years, amlodipine is approved for hypertension. A clinician selects treatment according to cardiovascular history, blood pressure, and other health conditions.
Norvasc is generally taken once daily, with or without food. The usual adult starting dose for hypertension is 5 mg daily, with a maximum recommended dose of 10 mg daily. Some older adults, patients with liver impairment, or those needing more cautious treatment may start at 2.5 mg daily. Children aged six through 17 years generally receive 2.5 mg to 5 mg once daily for hypertension. Patients should follow their prescribed schedule and avoid changing doses without medical guidance.
Common side effects include swelling of the ankles or feet, dizziness, flushing, fatigue, and palpitations. Peripheral edema can become more noticeable at higher doses. Serious adverse effects include symptomatic low blood pressure and, rarely, worsening angina or a heart attack after starting or increasing treatment, especially in patients with severe obstructive coronary artery disease. Patients with significant liver impairment may require slower dose adjustments. Persistent swelling, fainting, or worsening chest discomfort requires medical evaluation.
