RESUMO
A single 200-mg oral dose of trovafloxacin (CP-99,219) was given to each of eight healthy male volunteers, and the concentrations of the drug were measured in plasma, cantharides-induced inflammatory fluid, and urine over the subsequent 36 h. The mean maximum concentration observed in plasma was 2.9 micrograms/ml at a mean time of 0.75 h postdose. The mean maximum concentration observed in inflammatory fluid was 1.2 micrograms/ml at 4.0 h postdose. The mean elimination half-life in plasma was 7.8 h. The overall penetration into inflammatory fluid was 64%, as assessed by determining the ratio of the area under the concentration-time curves. Recovery of the dose in urine within the first 36 h postdose was 5.0% of the administered dose. Our results indicate that trovafloxacin, at a dosage of 200 mg once or twice daily, should be adequate for the treatment of systemic infections caused by most common bacterial pathogens.
