Abstract:
Objective To evaluate whether individualized dosage regimen based on therapeutic drug monitoring (TDM) is beneficial for improving the rate of pharmacokinetics/pharmacodynamics (PK/PD) reaching the standard and anti-infection efficacy. Methods Totally, 36 cases in the intensive care unit ( ICU ) of Nanjing Drum Tower Hospital using meropenem during January 2015 to December 2015 were collected, and divided into intervention group and control group. Results On the fourth day of administration, meropenem concentration in intervention group was significantly higher than that of the control group (22.5 μgmL-1 and 17.5 μgmL-1, respectively, P=0.007).With minimal inhibitory concentration (Cmin)>8 μgmL-1 serving as target, the rate of reaching the standard was both 22. 2% on day 2, 100. 0% and 72. 2% on day 4 in intervention group and control group, respectively (P=0.015). With minimal inhibitory concentration (Cmin) >32 μgmL-1 serving as target, the rate of reaching the standard was both 0 on day 2, 38. 9% and 5. 5% on day 4 in intervention group and control group, respectively (P=0.015). The clinical curative rate of the intervention group and control group was 83.3% and 72.2%, respectively (P=0.437), and the failure rate was 16.7% and 27.8%, respectively.Bacteria clearance rate was 88.9%and 55.5% in the intervention group and control group, respectively(P<0.05). Conclusion Individualized dosage regimen based on TDM in ICU patients is beneficial to improving the rate of PK/PD reaching the standard and anti-infection efficacy.
