Clopidogrel Zentiva (previously Clopidogrel Winthrop)

Clopidogrel Zentiva is a medicine used to prevent problems caused by blood clots in adults who have: - recently had a myocardial infarction (heart attack). Clopidogrel Zentiva can be started between a few days and 35 days after the attack; - recently had an ischaemic stroke (stroke caused by failure of the blood supply to part of the brain). Clopidogrel Zentiva can be started between seven days and six months after the stroke; - peripheral arterial disease (problems with blood flow in the arteries); - a condition known as ‘acute coronary syndrome’, when it should be given with acetylsalicylic acid (another medicine that prevents blood clots). Acute coronary syndrome is a group of heart problems that include severe heart attacks (known as ST-elevation myocardial infarction) and unstable angina (a severe type of chest pain). Some of these patients may be undergoing percutaneous coronary intervention (a procedure that unblocks blood vessels of the heart to restore its blood supply) and may have had a stent inserted (a short tube placed in an artery to prevent it closing up). Others may benefit from thrombolytic or fibrinolytic treatment (treatments to dissolve blood clots). - atrial fibrillation (irregular rapid contractions of the upper chambers of the heart), when it should be given with acetylsalicylic acid. 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. Clopidogrel Zentiva contains the active substance clopidogrel.
