Clopidogrel is used in the treatment of various cardiovascular conditions. These conditions have their own recommended dosages, as shown below. Platelet inhibition can often be demonstrated two hours after a single dose of oral clopidogrel. However, the absorption and distribution of the drug may be too slow for some conditions. Therefore, a loading dose of 300 mg may need to be administered. The table below lists dosage recommendations for various conditions. In all cases, clopidogrel is given orally.
