Prevention of atherothrombotic events.
Clopidogrel is indicated in:
- adult patients suffering from myocardial infarction (from a few days until less than 35 days), ischaemic stroke (from 7 days until less than 6 months) or established peripheral arterial disease;
- adult patients suffering from acute coronary syndrome:
- non-ST-segment-elevation acute coronary syndrome (unstable angina or non-Q-wave myocardial infarction), including patients undergoing a stent placement following percutaneous coronary intervention, in combination with acetylsalicylic acid (ASA);
- ST-segment-elevation acute myocardial infarction, in combination with ASA in medically treated patients eligible for thrombolytic therapy;
- prevention of atherothrombotic and thromboembolic events in atrial fibrillation;
- in adult patients with atrial fibrillation who have at least one risk factor for vascular events, are not suitable for treatment with vitamin-K antagonists and who have a low bleeding risk, clopidogrel is indicated in combination with ASA for the prevention of therothrombotic and thromboembolic events, including stroke.
What is Clopidogrel Apotex?
Clopidogrel Apotex is a medicine that contains the active substance clopidogrel. It is available as tablets (75 mg).
Clopidogrel Apotex is a ‘generic medicine’. This means that Clopidogrel Apotex is similar to a ‘reference medicine’ already authorised in the European Union (EU) called Plavix.
What is Clopidogrel Apotex used for?
Clopidogrel Apotex is used in adults to prevent atherothrombotic events (problems caused by blood clots and hardening of the arteries). Clopidogrel Apotex can be given to the following groups of patients:
- patients who have recently had a myocardial infarction (heart attack). Clopidogrel Apotex can be started between a few days and 35 days after the attack;
- patients who have had a recent ischaemic stroke (stroke caused by failure of the blood supply to part of the brain). Clopidogrel Apotex can be started between seven days and six months after the stroke;
- patients with peripheral arterial disease (problems with blood flow in the arteries);
- a condition known as ‘acute coronary syndrome’, when it should be given with aspirin (another medicine that prevents blood clots). Acute coronary syndrome is a group of heart problems that include heart attacks and unstable angina (a severe type of chest pain). Some of these patients may have had a stent (a short tube) placed in an artery to prevent it from closing up;
- atrial fibrillation (irregular rapid contractions of the upper chambers of the heart), when it should be given with aspirin. It is used in those patients who have at least one risk factor for vascular events such as a heart attack or stroke, cannot take vitamin-K antagonists (other medicines that prevent blood clots) and are at low risk of bleeding.
The medicine can only be obtained with a prescription.
How is Clopidogrel Apotex used?
The standard dose of Clopidogrel Apotex is one 75-mg tablet once a day, taken with or without food.
How does Clopidogrel Apotex work?
The active substance in Clopidogrel Apotex, clopidogrel, is an inhibitor of platelet aggregation. This means that it helps to prevent blood clots from forming. When the blood clots, this is due to special cells in the blood called platelets aggregating (sticking together). Clopidogrel stops the platelets aggregating by blocking a substance called ADP from attaching to a special receptor on their surface. This stops the platelets becoming ‘sticky’, reducing the risk of a blood clot forming and helping to prevent another heart attack or stroke.
How has Clopidogrel Apotex been studied?
Because Clopidogrel Apotex is a generic medicine, studies have been limited to tests to determine that it is bioequivalent to the reference medicine, Plavix. Two medicines are bioequivalent when they produce the same levels of the active substance in the body.
What are the benefit and risk of Apotex?
Because Clopidogrel Apotex is a generic medicine and is bioequivalent to the reference medicine, its benefit and risk are taken as being the same as those of the reference medicine.
Why has Clopidogrel Apotex been approved?
The CHMP concluded that, in accordance with EU requirements, Clopidogrel Apotex has been shown to have comparable quality and to be bioequivalent to Plavix. Therefore, the CHMP’s view was that, as for Plavix, the benefit outweighs the identified risk. The Committee recommended that Clopidogrel Apotex be given marketing authorisation.
