Adults and the Elderly: 75 mg as a single daily dose with or without food.
In patients with non-ST segment elevation acute coronary syndrome (unstable angina or non-Q-wave myocardial infarction), clopidogrel treatment should be initiated with a single 300-mg loading dose and then continued at 75 mg once a day (with ASA 75-325 mg daily). Since higher doses of ASA were associated with higher bleeding risk, it is recommended that the dose of ASA should not be >100 mg. The optimal duration of treatment has not been formally established. Clinical trial data support use up to 12 months, and the maximum benefit was seen at 3 months.
In patients with ST segment elevation acute myocardial infarction: clopidogrel should be given as a single daily dose of 75 mg initiated with a loading dose in combination with ASA and with or without thrombolytics. For patients greater than 75 years of age clopidogrel should be initiated without a loading dose. However, there is limited clinical experience in patients ≥75 years of age. Combined therapy should be started as early as possible after symptoms start and continued for at least four weeks. The benefit of the combination of clopidogrel with ASA beyond four weeks has not been studied in this setting.
Administration: May be taken with or without food.
