Abstract

Levels of ciprofloxacin in serum and sputum were studied for eight patients with cystic fibrosis who were infected with Pseudomonas aeruginosa. Patients were studied in a steady state on a dosage of 500 mg every 8 h. Peak levels in serum ranged from 1.27 to 5.6 mg/liter (mean, 3.16 +/- 1.27), and absorption was rapid, the time to peak concentration ranging from 0.5 to 3.0 h (mean, 1.5 +/- 0.9). The antibiotic penetrated sputum well, achieving areas under the curve of approximately 46% of those obtained in serum.

摘要

对8例感染铜绿假单胞菌的囊性纤维化患者的血清和痰液中的环丙沙星水平进行了研究。患者在每8小时服用500毫克剂量的稳定状态下接受研究。血清中的峰值水平在1.27至5.6毫克/升之间(平均为3.16 +/- 1.27),吸收迅速,达到峰值浓度的时间在0.5至3.0小时之间(平均为1.5 +/- 0.9)。抗生素在痰液中渗透良好,曲线下面积约为血清中获得的曲线下面积的46%。
