优化tigecycline剂量对于重症患者至关重要. 一种种群的药理动力学模型表明,对于某些感染,50 mg/12h是必要的,但对于其他感染,可能需要100 mg/12h,从而改善治疗结果.
科学领域:
- 药理学 药理学是指药理学的学科.
- 关键护理医学 关键护理医学
- 药理动力学 药理动力学
背景情况:
- 危急病患者表现出药理动力学变异性,使tigecycline的剂量复杂化.
- 由于患者的异质性,最佳的tigecycline剂量方案仍在争论中.
研究的目的:
- 在重症患者中开发和验证tigecycline的种群药业动力学 (PPK) 模型.
- 通过模拟来优化tigecycline剂量策略.
主要方法:
- 一项前性研究,涉及从接受tigecycline的98名危急病患者进行密集的血液采样.
- 开发和评估一个两部分的PPK模型,使用合适性,引导和视觉预测检查.
- 蒙特卡洛模拟以确定最佳剂量方案.
主要成果:
- 最终的PPK模型纳入了共同变量:肌素清除率 (CL),体重 (V1,V2),γ-谷氨基转移酶和总 bilirubin (Q) 和白蛋白 (V2).
- 典型的药用动力学参数:CL 3.09 L/h,Q 39.7 L/h,V1 32.1 L,V2 113 L. 这两种类型的药用动力学参数为:
- 推的tigecycline剂量:50 mg/12h用于腹部内感染;100 mg/12h用于肺炎,皮肤感染和不太敏感的细菌.
结论:
- 一个经过验证的tigecycline PPK模型成功地为重症患者建立.
- 基于该模型的个性化tigecycline剂量可以提高治疗效果.
