Objective: This study was undertaken to determine plasma and pelvic tissue concentrations of piperacillin/tazobactam following a single intravenous administration.Methods: Plasma and tissue samples were obtained following administration of 3 g of piperacillin and 0.375 g of tazobactam. Concentrations of these agents were determined by chromatography.Results: Plasma concentrations (mean ±SD) for piperacillin/tazobactam were 208 ± 87/27 ± 8 and 95 ± 53/14 ± 2, respectively, at 30 and 60 min after the start of the infusion. The 8:1 ratio between piperacillin and tazobactam in plasma remained constant for up to 96 min. Tissue concentrations yielded a broader range, but …
