简要总结
Ceftazidime/avibactam (CAZ/AVI) is a new β-lactam drug, which has good antibacterial effect against carbapenem resistant enterobacter. However, previous studies found that CAZ/AVI had a low PK/PD compliance rate after the recommended dose of the drug instructions.Therefore, this study was intended to explore the clinical efficacy of different administration schedules of CAZ/AVI for patients with severe infection, and further analyze the correlation between CAZ/AVI PK/PD parameters and clinical efficacy and adverse reactions.
详细描述
- Main purpose The main objective of this study was to verify that the clinical efficacy of treatment group (load dose of 2.5g, then continuous infusion of 2.5gQ8h, the dose can be adjusted according to renal function) with severe infection was superior to that of the control group (standard dose and administration regimen of ceftazidime/avibactam, i.e. 2.5gQ8h, 2h infusion).Dose can be adjusted according to renal function).
- Secondary purpose (1) To investigate the relationship between different administration regimens and bacterial clearance and 28-d mortality (2) To explore the correlation between different dosing regimens and PK/PD compliance rate (3) To explore the correlation between different administration regimens and adverse drug reactions

研究组 & 干预措施
treatment group
Ceftazidime/avibactam（Taidingping®, Qilu Pharmaceutical Co., Ltd.） loading dose of 2.5g (2h infusion), then the standard dose and administration schedule, namely 2.5gQ8h, continuous infusion, the dose can be adjusted according to the instructions of renal function，The duration of medication is determined by the clinician
干预措施: CAZ/AVI (Drug)
control group
Ceftazidime/avibactam（Taidingping®, Qilu Pharmaceutical Co., Ltd.）were given a load dose of 2.5g (2h infusion), followed by 2.5gQ8h, the dose can be adjusted according to renal function.The duration of medication is determined by the clinician.

结局指标
主要结局
Clinical effective rate
时间窗: 14 days
According to the Technical Guidelines for Clinical Trials of Antimicrobial Drugs, clinical efficacy is defined as: (1) effective: symptoms, signs, pathogenic microbiology and various tests and examination indicators are significantly improved;(2) Ineffective: the patient's condition has not improved or worsened, and other antibacterial drugs need to be replaced.Effective rate = Number of effective cases/total cases x 100%.
次要结局
- Bacterial removal(14 days)
- 28-d mortality(28 days)
- PK/PD compliance rate(14 days)
