RESUMEN
Meropenem is the first choice for the treatment of multi-drug-resistant bacterial infections， which has been widely used in clinical practice. However， the physiological and pathological characteristics of special populations have a significant impact on the pharmacokinetics/pharmacodynamics （PK/PD） parameters of meropenem， so it is necessary to develop individualized drug administration plan according to the characteristics of patients in clinical application. Therefore， this paper summarizes PK/PD characteristics and application of meropenem in special population， and recommends the dosage of meropenem as follows： 10-40 mg/kg， q8 h for children； 1 g， q8-12 h for elderly patients； 0.75 g， q8 h for the patients with renal insufficiency who received continuous veno-venous hemofiltration and continuous veno-venous hemodialysis； 1 g， q8 h prolonged infusion until 3 hours or 2 g， q8 h for patients with hyperrenal function； 1 g， q8 h after 2 g loading dose for patients with cirrhosis.
