Amlodipine Besylate (Page 5 of 6)

14.5 Studies in Patients with Heart Failure

Amlodipine has been compared to placebo in four 8 to12 week studies of patients with NYHA Class II/III heart failure, involving a total of 697 patients. In these studies, there was no evidence of worsened heart failure based on measures of exercise tolerance, NYHA classification, symptoms, or left ventricular ejection fraction. In a long-term (follow-up at least 6 months, mean 13.8 months) placebo-controlled mortality/morbidity study of amlodipine 5 to 10 mg in 1,153 patients with NYHA Classes III (n=931) or IV (n=222) heart failure on stable doses of diuretics, digoxin, and ACE inhibitors, amlodipine had no effect on the primary endpoint of the study which was the combined endpoint of all-cause mortality and cardiac morbidity (as defined by life-threatening arrhythmia, acute myocardial infarction, or hospitalization for worsened heart failure), or on NYHA classification, or symptoms of heart failure. Total combined all-cause mortality and cardiac morbidity events were 222/571 (39%) for patients on amlodipine and 246/583 (42%) for patients on placebo; the cardiac morbid events represented about 25% of the endpoints in the study.

Another study (PRAISE-2) randomized patients with NYHA Class III (80%) or IV (20%) heart failure without clinical symptoms or objective evidence of underlying ischemic disease, on stable doses of ACE inhibitors (99%), digitalis (99%), and diuretics (99%), to placebo (n=827) or amlodipine (n=827) and followed them for a mean of 33 months. There was no statistically significant difference between amlodipine and placebo in the primary endpoint of all-cause mortality (95% confidence limits from 8% reduction to 29% increase on amlodipine). With amlodipine there were more reports of pulmonary edema.

Read this information carefully before you start taking amlodipine besylate tablets and each time you refill your prescription. There may be new information. This information does not replace talking with your doctor. If you have any questions about amlodipine , ask your doctor. Your doctor will know if amlodipine is right for you.

What is amlodipine?

Amlodipine is a type of medicine known as a calcium channel blocker (CCB).It is used to treat high blood pressure (hypertension) and a type of chest pain called angina. It can be used by itself or with other medicines to treat these conditions.

High Blood Pressure (hypertension)

High blood pressure comes from blood pushing too hard against your blood vessels. Amlodipine relaxes your blood vessels, which lets your blood flow more easily and helps lower your blood pressure. Drugs that lower blood pressure lower your risk of having a stroke or heart attack.


Angina is a pain or discomfort that keeps coming back when part of your heart does not get enough blood. Angina feels like a pressing or squeezing pain, usually in your chest under the breastbone. Sometimes you can feel it in your shoulders, arms, neck, jaws, or back. Amlodipine can relieve this pain.

Who should not use amlodipine?

Do not use amlodipine if you are allergic to amlodipine (the active ingredient in amlodipine besylate tablets), or to the inactive ingredients. Your doctor or pharmacist can give you a list of these ingredients.

What should I tell my doctor before taking amlodipine?

Tell your doctor about any prescription and non-prescription medicines you are taking, including natural or herbal remedies. Tell your doctor if you:
• ever had heart disease
• ever had liver problems
• are pregnant, or plan to become pregnant. Your doctor will decide if amlodipine is the best treatment for you.
• are breastfeeding. Do not breastfeed while taking amlodipine. You can stop breastfeeding or take a different medicine.

How should I take amlodipine?

• Take amlodipine once a day, with or without food.
• It may be easier to take your dose if you do it at the same time every day, such as with breakfast or dinner, or at bed time. Do not take more than one dose of amlodipine at a time.
• If you miss a dose, take it as soon as you remember. Do not take amlodipine if it has been more than12 hours since you missed your last dose. Wait and take the next dose at your regular time.
Other medicines: You can use nitroglycerin and amlodipine together. If you take nitroglycerin for angina, don’t stop tak ing it while you are taking amlodipine.
• While you are taking amlodipine , do not stop taking your other prescription medicines, including any other blood pressure medicines, without talking to your doctor.
• If you took too much amlodipine , call your doctor or Poison Control Center, or go to the nearest hospital emergency room right away.

What should I avoid while taking amlodipine?

Do not start any new prescription or non-prescription medicines or supplements, unless you check with your doctor first.

Amlodipine may cause the following side effects. Most side effects are mild or moderate:
• swelling of your legs or ankles
• tiredness, extreme sleepiness
• stomach pain, nausea
• dizziness
• flushing (hot or warm feeling in your face)
• arrhythmia (irregular heartbeat)
• heart palpitations (very fast heartbeat)

It is rare, but when you first start taking amlodipine or increase your dose, you may have a heart attack or your angina may get worse. If that happens, call your doctor right away or go directly to a hospital emergency room.
