About

The goal of this clinical trial is to evaluate the Epithelial Lining Fluid concentrations and permeability of Intravenous Meropenem-Pralubactam(Meropenem/FL058) in China Healthy Adult Participants. The main question it aims to answer is:

• [question 1] : What are the concentrations of meropenem and Pralubactam in plasma, epithelial lining fluid (ELF), and alveolar macrophages (AM) at each time point
