angiographically documented cad
In patients with recently documented CAD by angiography and without heart failure or an ejection fraction < 40%, amlodipine besylate tablets are indicated to reduce the risk of hospitalization due to angina and to reduce the risk of a coronary revascularization procedure.
warnings & precautions
increased angina or myocardial infarction
Worsening angina and acute myocardial infarction can develop after starting or increasing the dose of amlodipine, particularly in patients with severe obstructive coronary artery disease.
Amlodipine is not a beta-blocker and therefore gives no protection against the dangers of abrupt beta-blocker withdrawal; any such withdrawal should be by gradual reduction of the dose of beta-blocker.
patients with hepatic failure
Because amlodipine is extensively metabolized by the liver and the plasma elimination half-life (t1/2) is 56 hours in patients with impaired hepatic function, titrate slowly when administering amlodipine to patients with severe hepatic impairment.
in vitro data
In vitro data indicate that amlodipine has no effect on the human plasma protein binding of digoxin, phenytoin, warfarin, and indomethacin.
Coadministration of amlodipine with cimetidine did not alter the pharmacokinetics of amlodipine.
Coadministration of 240 mL of grapefruit juice with a single oral dose of amlodipine 10 mg in 20 healthy volunteers had no significant effect on the pharmacokinetics of amlodipine.
magnesium & aluminum hydroxide antacid
Coadministration of a magnesium and aluminum hydroxide antacid with a single dose of amlodipine had no significant effect on the pharmacokinetics of amlodipine.
A single 100 mg dose of sildenafil in subjects with essential hypertension had no effect on the pharmacokinetic parameters of amlodipine. When amlodipine and sildenafil were used in combination, each agent independently exerted its own blood pressure lowering effect.
Coadministration of multiple 10 mg doses of amlodipine with 80 mg of atorvastatin resulted in no significant change in the steady-state pharmacokinetic parameters of atorvastatin.
Coadministration of amlodipine with digoxin did not change serum digoxin levels or digoxin renal clearance in normal volunteers.
Single and multiple 10 mg doses of amlodipine had no significant effect on the pharmacokinetics of ethanol.
Coadministration of amlodipine with warfarin did not change the warfarin prothrombin response time.

PATIENT INFORMATION LEAFLET

What are amlodipine besylate tablets?
Amlodipine besylate tablets are 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 besylate tablets relax 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 besylate tablets can relieve this pain.
