Pharmacokinetics of Ertapenem in Continuous Venovenous Hemodialysis

This study has been completed.

Critically ill patients in the intensive care unit often receive continuous hemodialysis to treat their kidney failure. Ertapenem is an antibiotic often used in these patients. Continuous dialysis may remove ertapenem, putting patients at risk for inappropriate treatment of their infection. This study will determine how much ertapenem is removed by continuous hemodialysis.

Condition Intervention Phase
Acute Kidney Failure
Drug: ertapenem
Phase 4

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Official Title: Pharmacokinetics of Invanz® (Ertapenem) in Critically Ill Patients Receiving Continuous Venovenous Hemodialysis

Primary Outcome Measures:
  • Ertapenem Transmembrane Clearance by Continuous Hemodialysis. [ Time Frame: 24 hours after receiving first 1 gram dose ]

Enrollment: 8
Study Start Date: February 2009
Study Completion Date: March 2011
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: ertapenem
subjects will receive ertapenem while receiving CVVHD
Drug: ertapenem
One gram ertapenem will be infused intravenously in subjects receiving continuous hemodialysis (CVVHD). Pharmacokinetic sampling in this study will occur with the first dose of ertapenem. While on CVVHD, enrolled subjects will receive ertapenem 1 g intravenously administered over 30 minutes. Two blood samples (5 mL each) will be collected from the arterial (pre-diafilter) port of the CVVHD tubing at time 0 (baseline), ½ hour (end of infusion), 1, 1½, 2, 3, 6, 12, and 24 hours. Effluent (5 mL) will also be collected at these predefined time points from the effluent port of the CVVHD tubing. If ertapenem is discontinued after the first dose then additional samples will be collected at 36 and 48 hours, otherwise ertapenem will be administered as soon as the 24 hour sample is obtained.
Other Name: Invanz

Detailed Description:
Subjects receiving CVVHD will receive a one gram dose of ertapenem. Serial blood samples over 24 hours will be taken to assess the ertapenem blood concentrations over time. Spent dialysate and urine samples (if any) will also be measured for ertapenem content to determine how much drug is removed by CVVHD and kidneys. A pharmacokinetic evaluation will be made to determine what is the most appropriate dose for this drug in patients receiving CVVHD to achieve pharmacokinetic and pharmacodynamic goals.
