摘要: Introduction:Activation of coagulation and platelets is closely linked, arterial thrombosis involves activation as well platelet aggregation. In these studies, we investigated the possible synergistic effects rivaroxaban in combination with antiplatelet agents on thrombin generation aggregation vitro hemostasis rat models.Materials Methods:Thrombin was measured by Calibrated Automated Thrombogram method (0.5 pmol/L tissue factor) using human platelet-rich plasma (PRP) spiked (15, 30, or 60 ng/mL), ticagrelor (1.0 µg/mL), acetylsalicylic acid (ASA; 100 µg/mL). Tissue factor-induced PRP (15 30 (1 3 a these. An arteriovenous (AV) shunt model rats used to determine (0.01, 0.03, 0.1 mg/kg), clopidogrel ASA (3 combina...
