Amlodipine

Generic name: Amlodipine
Drug class: Calcium channel blocking agents

Usage of Amlodipine

Amlodipine besylate belongs to a class of medications called calcium channel blockers. It lowers blood pressure by relaxing the blood vessels so the heart does not have to pump as hard.

Amlodipine is used to treat certain types of angina (chest pain) and other conditions caused by coronary artery disease (narrowing of the blood vessels that supply blood to the heart).

Amlodipine besylate controls chest pain by increasing the supply of blood to the heart. If taken regularly, this medicine controls chest pain, but it does not stop chest pain once it starts. Your doctor may prescribe a different medication to take when you have chest pain.

Amlodipine is also used alone or in combination with other medicines to treat high blood pressure (hypertension) in adults and children at least 6 years old. Lowering blood pressure may lower your risk of a stroke or heart attack.

Amlodipine besylate is available as:

Amlodipine 5 mg tablets (Norvasc)

Amlodipine 10 mg tablets (Norvasc)

Amlodipine 2.5 mg tablets (Norvasc)

Amlodipine 1 mg/mL solution (Norliqva)

Amlodipine 1 mg/mL oral suspenstion (Katerzia)

Before taking Amlodipine

You should not take amlodipine if you are allergic to it.

To make sure this medicine is safe for you, tell your doctor if you have ever had:

severe narrowing of a certain valve in your heart (aortic stenosis), or other heart problems;

coronary artery disease (clogged arteries); or

liver disease.

It is not known if amlodipine will harm an unborn baby. However, having high blood pressure during pregnancy may cause complications or medical problems in both mother and baby. The benefit of treating hypertension may outweigh any risks to the baby.

Tell your doctor if you are breastfeeding.

Warnings

Before taking amlodipine besylate, tell your doctor if you have congestive heart failure or liver disease.

Drinking alcohol can further lower your blood pressure and may increase certain side effects of amlodipine.

If you are being treated for high blood pressure, keep using amlodipine even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.

Amlodipine is only part of a complete program of treatment that may also include diet, exercise, weight control, and other medications. Follow your diet, medication, and exercise routines very closely.

Tell your doctor about all other heart or blood pressure medications you are taking.

Your chest pain may become worse when you first start taking amlodipine or when your dose is increased. Call your doctor if your chest pain is severe or ongoing.

What other drugs will affect Amlodipine

Sometimes it is not safe to use certain medicines at the same time. Some drugs can affect your blood levels of other drugs you use, which may increase side effects or make the medicines less effective.

Other drugs may interact with amlodipine, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all other medicines you use.

Swelling from amlodipine is a common, but often troublesome side effect of amlodipine with 5% to 9% of people stopping amlodipine because of it. If you develop swelling with amlodipine, tell your doctor right away because they may be able to change your blood pressure medications slightly to help reduce the swelling. Swelling caused by amlodipine does not usually respond to treatment with diuretics (such as furosemide) because it is caused by changes in capillary pressure that result in leakage into the spaces between capillaries (called the interstitial area) rather than water retention.

Amlodipine can take more than 8 hours to start working, because it takes a long time to be absorbed. This means it is not a good choice for lowering blood pressure quickly, and other agents, such as hydralazine, clonidine, and nifedipine XL (which work within 1 to 2 hours) are preferred.
