摘要:

多黏菌素B(polymyxin B)作为治疗碳青霉烯类耐药革兰氏阴性菌(carbapenem-resistant gram-negative bacilli,CR-GNB)感染的关键药物,其药动学(PK)特征在特殊人群中存在差异,需依据患者特征制定个体化给药方案。本文总结了多黏菌素B在特殊人群中的PK及药效学(PD)特点和应用:儿童患者推荐剂量为1.5~3.0 mg·kg?1·d?1;老年患者推荐固定剂量100~150 mg q12h;肥胖患者推荐基于调整体重(adjusted body weight,ABW)给予负荷剂量2.5 mg/kg,维持剂量1.25~1.5 mg/kg q12h,且日剂量上限为250 mg;肝功能障碍患者可按指南推荐剂量(1.25~1.5 mg/kg q12h)给药,无需调整;肾功能不全患者需根据肌酐清除率(creatinine clearance,CrCL)调整剂量,轻度肾功能不全患者(60≤CrCL<90 mL/min)推荐固定给药剂量75 mg q12h,中度肾功能不全患者(30≤CrCL<60 mL/min)推荐50 mg q12h;重度肾功能不全患者(15≤CrCL<30 mL/min)推荐30~40 mg q12h;接受连续肾脏替代治疗(continuous renal replacement therapy,CRRT)治疗的患者,推荐固定剂量100 mg q12h。

Abstract:

As a key drug for the treatment of carbapenem-resistant gram-negative bacilli (CR-GNB) infections, polymyxin B exhibits differences in its pharmacokinetic (PK) characteristics among special populations, thus requiring the formulation of individualized dosing regimens based on patient characteristics. This article summarizes the PK, pharmacodynamic (PD) characteristics and applications of polymyxin B in special populations: for pediatric patients, a dose of 1.5-3.0 mg·kg?1·d?1 is recommended; for elderly patients, a fixed dose of 100-150 mg q12h may be used; for obese patients, based on adjusted body weight (ABW), a loading dose of 2.5 mg/kg and a maintenance dose of 1.25-1.5 mg/kg q12h may be considered, with a daily dose upper limit of 250 mg; for patients with hepatic dysfunction, the dose recommended in the guidelines (1.25-1.5 mg/kg q12h) can be used without adjustment; for patients with renal insufficiency, the dose should be adjusted based on creatinine clearance (CrCL): a fixed dose of 75 mg q12h is recommended for those with mild renal insufficiency (60≤CrCL<90 mL/min); 50 mg q12h for those with moderate renal insufficiency (30≤CrCL<60 mL/min); 30-40 mg q12h for those with severe renal insufficiency (15≤CrCL<30 mL/min); and a fixed dose of 100 mg q12h is recommended for patients undergoing continuous renal replacement therapy (CRRT).
