目的 比較鹽酸莫西沙星全身和肺部藥代動力學特點，探討藥物濃度監(jiān)測和療效評估的實用性技術(shù)，以指導臨床合理進行抗感染治療。方法 選擇10例肺部感染（慢性阻塞性肺疾病急性加重6例、社區(qū)獲得性肺炎4例）患者，服用400 mg單劑量的鹽酸莫西沙星。于服藥前及服藥后1、2、3、4、8及24 h采集血液，于服藥前及服藥后1、2、4、8、20及24 h采集痰液，用高效液相色譜法測定血清和痰液中鹽酸莫西沙星達峰濃度（Cmax）及24 h藥時曲線下面積（AUC0-24 h）。結(jié)果 單次口服鹽酸莫西沙星后約2 h在血中達峰濃度，Cmax為（5.95±1.35）mg/L，AUC0-24 h為（58.72±8.11）mg·h-1·L-1；約3 h在痰液中達峰濃度，Cmax為（16.18±6.47）mg/L，藥時曲線下面積（AUC0-24 h）為（138.04±78.29）mg·h-1·L-1。口服鹽酸莫西沙星后痰中Cmax和AUC0-24 h顯著高于血清Cmax和AUC0-24 h（P均 lt;0.05）。結(jié)論 單次口服鹽酸莫西沙星后，藥物迅速分布于肺部，在24 h內(nèi)肺部濃度高于血清濃度1倍以上。測定痰液藥物濃度可反映肺部藥代動力學特征。
