Based on 32 publication(s) in Google Scholar
Clopidogrel hydrogen sulfate is an antiplatelet agent to prevent blood clots. Clopidogrel hydrogen sulfate inhibits CYP2B6 and CYP2C19 with IC50s of 18.2 nM and 524 nM, respectively. Clopidogrel hydrogen sulfate is a potent antithrombotic agent that inhibits ADP-induced platelet aggregation.Clopidogrel hydrogen sulfate also is an orally active P2Y(12) inhibitor.

Animal Model:Age-matched C57BL/6J male mice weighing at least 25 g were used at 8 to 12 weeks of age[4]
-
Dosage:5 mg/kg
-
Administration:Gavage treatment
-
Result:Clopidogrel significantly inhibited thrombus formation compared with vehicle.
When Clopidogrel was given in combination with 0.6 mg/kg ASA, thrombi were significantly larger than those measured with Clopidogrel alone.
In contrast, when Clopidogrel was given in combination with 0.15 mg/kg ASA , thrombi were significantly smaller than those in mice treated with Clopidogrel and 0.6 mg/kg ASA, and smaller than those in mice given Clopidogrel alone.
