Preliminary Research On Two-step Dosing Of Imipenem/Cilastatin (PROTDOI)
November 24, 2015 updated by: Jianfeng Xie, Southeast University, China
Explore Imipenem/Cilastatin two-step dosing compared to 2 hours infusion in patients with severe whether can obtain better results of the pharmacokinetic/pharmacodynamic, for clinical rational use of antimicrobial agents, and provide theoretical support for optimizing dosage regimen.
Study Overview
Detailed Description
Compared with Imipenem/Cilastatin 2 hours continuous dosing method and two-step dosing method (0.5 hours before enter half dose, after 1.5 hours, the other half of the input dose) of blood drug concentration in the body than the minimal inhibitory concentrations (MIC) pathogens percent of dosing interval duration (100% fT > MIC), blood drug concentration in the body more than 4 times the minimal inhibitory concentrations (MIC) pathogens percent of dosing interval duration (100% fT > 4 MIC), blood drug concentration peak and the ratio of the minimal inhibitory concentrations (MIC) pathogens (Cmax/MIC), blood drug concentration (Tmax) used in the peak time, used to guide clinical patients with severe infection of Imipenem/Cilastatin usage.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Group I
Group I received intravenous imipenem/cilastatin 1 g every 8 h (q8h) or 0.5g every 6 h (q6h) with optimized two-step infusion therapy (OTIT; rapid first-step infusion in 30 min and slow second-step infusion above 1.5 hours) "Group I" is more informative than "Group II" from PK parameters(%T>MIC,AUC/MIC).
|
Patients in group I received a dose of imipenem/cilastatin 1g each every 8 hours or 0.5g every 6 hours optimized two-step infusion therapy (rapid first-step infusion in 30 min and slow second-step infusion above 1.5 hours)

Placebo Comparator: Group II
group II received intravenous imipenem/cilastatin 1g q8h or 0.5g q6h with extended infusion therapy (2-hours continuous infusion in a constant speed). "Group I" is more informative than "Group II" from PK parameters(%T>MIC,AUC/MIC). |
Patients in group I received a dose of imipenem/cilastatin 1g each every 8 hours or 0.5g every 6 hours optimized two-step infusion therapy (rapid first-step infusion in 30 min and slow second-step infusion above 1.5 hours)
