Measure
Imipenem-Relebactam
Participants will receive a single dose of intravenous imipenem-relebactam (500mg-250mg) as a 30 minute infusion. Imipenem-relebactam: After receipt of imipenem-relebactam, participants will have six blood samples collected over 6 hours for determination of imipenem and relebactam concentrations.

1/9 • Number of events 1 • Adverse events were collected over a 24 hour window, from the first (and only) imipenem-relebactam dose (0 hour) to the end of blood sampling (6 hours), plus an 18 hour observation window after the last sample was collected, culminating with physical exam. Note: 9 subjects were enrolled and received imipenem-relebactam. Although only 8 subjects were included in results analysis due to inability to obtain blood samples in 1 subject, all 9 subjects are included in the adverse event reporting.
Adverse event - any pathologic or unintended change in the structure (signs), function (symptoms), or chemistry (laboratory values) of the body associated with the use of the study drug, whether or not considered drug related: MILD - present, but easily tolerated MODERATE - discomfort that interferes with usual activities SEVERE - incapacitating, inability to work or do usual activities
