Sibrafiban inhibits ADP and TRAP-stimulated fibrinogen binding and microaggregate formation in a concentration-dependent manner, whereas P-selectin expression is relatively unaltered. A decrease in site occupancy from peak to trough of Sibrafiban does not result in increased activation of platelets. 体内研究 The effects of Ro 44-3888 on the platelet aggregation response to ADP (17μmol) and on cutaneous bleeding times is determined in 8 rhesus monkeys given Sibrafiban 0.25mg/kg/day or 0.5mg/kg/day orally for 8 days. The maximum inhibition of ex vivo platelet aggregation and prolongation of bleeding time by Ro 44-3888 are dose dependent. |
