The reference site for Amlodipine

Amlodipine, sold under the brand name Norvasc among others, is a medication used to treat high blood pressure and coronary artery disease.


Amlodipine is a long-acting calcium channel blocker used as an anti-hypertensive, and in the treatment of angina.
As with other calcium channel blockers, amlodipine acts by relaxing the smooth muscles in the arterial wall, decreasing peripheral resistance and hence improving blood pressure. In angina it improves blood flow to the myocardium. It was developed under the direction of Dr. Simon Campbell.
Amlodipine is marketed as Norvasc®, as well as under various other names.

FDA Information

Amlodipine was approved by the Food and Drug Administration (FDA) in 1995.
Please visit the official site of the FDA for further information.

Why is this medication prescribed?

Amlodipine is a calcium channel blocker used to treat angina (chest pain) and high blood pressure. Amlodipine affects the movement of calcium into the cells of the heart and blood vessels. As a result, amlodipine relaxes blood vessels and increases the supply of blood and oxygen to the heart while reducing its workload.
High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.
This medication can sometimes be prescribed for other uses, but it is strongly recommended that you ask your doctor or pharmacist for more information.

Dosage and using this medicine

Amlodipine comes as an orally-administered tablet, and is usually taken once a day. To help you remember to take amlodipine, take it around the same time every day.
Adults: The usual initial antihypertensive oral dose of amlodipine is 5 mg once daily with a maximum dose of 10 mg once daily. Small, fragile, or elderly individuals, or patients with hepatic insufficiency may be started on 2.5 mg once daily and this dose may be used when adding amlodipine to other antihypertensive therapy.
Dosage should be adjusted according to each patient’s need. In general, titration should proceed over 7 to 14 days so that the physician can fully assess the patient’s response to each dose level. Titration may proceed more rapidly, however, if clinically warranted, provided the patient is assessed frequently.
The recommended dose for chronic stable or vasospastic angina is 5-10 mg, with the lower dose suggested in the elderly and in patients with hepatic insufficiency. Most patients will require 10 mg for adequate effect.
The recommended dose range for patients with coronary artery disease is 5-10 mg once daily. In clinical studies the majority of patients required 10 mg.
Children: The effective antihypertensive oral dose in pediatric patients ages 6-17 years is 2.5 mg to 5 mg once daily.
