| Bioactivity | Bivalirudin TFA is a synthetic 20 residue peptide which reversibly inhibits thrombin.IC50 Value:Target: thrombinin vitro: Eptifibatide (8 mg/mL) added together with a low (70 ng/mL) concentration of bivalirudin (a direct thrombin inhibitor) effectively (approximately 90%) reduced platelet aggregation induced by thrombin (0.2 U/mL) [1]. In thrombin generation assay (TGA), bivalirudin had no effect on these parameters up to 10 μmol/l [2]. Bivalirudin-facilitated binding of MPO to BAEC resulted also in functional changes in terms of increased NO consumption as well as enhanced MPO-mediated redox modifications [3].in vivo: The use of bivalirudinprevented further increase in antiheparin/PF4 antibody IgG levels in rats [4]. Three animals in the 500-mg/kg/24 h group, and 7 animals in the 2000-mg/kg/24 h group in the toxicokinetic assessment phase of the study were found dead or euthanized in extremis (following blood sampling). Plasma concentrations of bivalirudin appeared to be linear and dose independent [5].Clinical trial: Antithrombotic Effects of Ticagrelor Versus Clopidogrel . Phase 4 | ||||||
