Abstract

Steady-state pharmacokinetics of ertapenem were compared in patients after 1-g intravenous and subcutaneous (s.c.) infusions. Bioavailability was 99%+/-18% after s.c. administration, but peaks were reduced by about (43+/-29 versus 115+/-28 microg/ml) and times to peak were delayed. Simulations based on unbound concentrations show that time over the MIC should always be longer than 30% to 40% of the dosing interval, suggesting that s.c. infusion could be an alternative in patients with reduced vascular access.

摘要

在接受 1 克静脉和皮下(sc)输注的患者中比较了厄他培南的稳态药代动力学。sc 给药后的生物利用度为 99%+/-18%,但峰值降低约(43+/-29 与 115+/-28μg/ml),达峰时间延迟。基于游离浓度的模拟表明,MIC 以上的时间应始终长于给药间隔的 30%至 40%,这表明在血管通路减少的患者中,sc 输注可能是一种替代方法。
