Dabigatran etexilate (BIBR 1048) 是具有口服活性的 Dabigatran (一种凝血酶抑制剂)的前药。Dabigatran etexilate具有抗凝作用,可以预防心房颤动引起的静脉血栓栓塞和中风。
生物活性 | Dabigatran etexilate (BIBR 1048) is an orally active prodrug of Dabigatran (a direct inhibitor of thrombin). Dabigatran etexilate has anticoagulant effects and is used for the prophylaxis of venousthromboembolism and stroke due to atrial fibrillation[1]. |
体内研究 (In Vivo) | Dabigatran etexilate (BIBR 1048; oral; 10, 20 and 50 mg/kg for rats and 1, 2.5 and 5 mg/kg for monkeys) has dose- and time-dependent anticoagulant effects and has maximum effects between 30 and 120 min after administration, respectively[1]. Dabigatran etexilate maximally and significantly prolongs partial thromboplastin time (aPTT) to 25.2, 38.4 and 78.3 s in 30 min after 10, 20 and 50 mg/kg oral doses, respectively[1]. Dabigatran etexilate maximally prolongs the aPTT to 34.3 s, 44.0 s, and 63.0 s, respectively, 2h after 1, 2.5 or 5 mg/kg doses in the monkey[1].
Animal Model: | Male rats (280-350 g) and rhesus monkeys of either sex (3-8 kg)[1] | Dosage: | 10, 20 and 50 mg/kg for rats and 1, 2.5 and 5 mg/kg for monkeys | Administration: | Oral | Result: | Had dose- and time-dependent anticoagulant effects. |
