Pharmacokinetics of intravenously administered ciprofloxacin.
A 100-mg dose of ciprofloxacin was given as an intravenous bolus injection to each of six healthy volunteers, after which the levels of this agent were measured in serum, blister fluid, and urine. After administration, distribution of ciprofloxacin was very rapid, and the mean distribution volume was very large (177 liters). The mean terminal serum half-life was 4.0 h. The agent penetrated blister fluid rapidly, with the mean maximum level being 0.53 micrograms/ml at 30 min, after which time the blister levels exceeded those in serum. The 48-h urinary recovery of ciprofloxacin was about 80%.
