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. |
