Dabigatran etexilate metabolite/intermediate
|
|---|---|
| 其他信息 |
The impact of moderate hepatic impairment on the pharmacokinetics (PK) and pharmacodynamics (PD) of dabigatran etexilate was evaluated in an open, parallel-group study. Healthy volunteers (n = 12) and patients with hepatic impairment (Child-Pugh classification B; n = 12) received a single oral dose of 150 mg dabigatran etexilate. The mean values for area under the concentration-time curve, terminal half-life, and renal clearance of dabigatran were comparable between patients with hepatic impairment and healthy volunteers. Conversion of the dabigatran intermediate BIBR1087 to active dabigatran was slower in patients with hepatic impairment, indicating that the liver is partly involved in bioconversion of dabigatran etexilate. However, total drug exposure was comparable between groups; therefore, this observation is of no clinical relevance with respect to the anticoagulant activity of dabigatran. The extent of dabigatran glucuronidation was unchanged by liver disease; glucuronidation capacity was maintained in moderate liver disease. The activated partial thromboplastin time, ecarin clotting time, and thrombin time relationships were essentially identical in both groups. This study shows that moderate hepatic impairment does not affect the PK/PD or safety profile of dabigatran. Therefore, patients with moderate hepatic impairment can be given dabigatran etexilate without the need for dose adjustment. [1]

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
