Abstract
The pharmacokinetics of a single dose of BMS 284756 were determined following oral administration of a 600-mg dose to eight healthy male volunteers. Concentrations of the drug were measured in plasma and a cantharidine-induced inflammatory exudate by a microbiological assay. The mean peak concentration in plasma of 10.4 μg/ml (standard deviation [SD], 1.3 μg/ml) was attained at a mean time of 1.2 h (SD, 0.5 h) after the dose. The penetration into the inflammatory exudate was 82% (SD, 15.7%). A mean peak concentration of 7.2 μg/ml (SD, 2.4 μg/ml) was attained in the inflammatory exudate at 5.3 h (SD, 1.5 h). The elimination half-lives from plasma and inflammatory fluid were 9.8 h (SD, 1.1 h) and 8.5 h (SD, 1.9 h), respectively. The areas under the concentration-time curves for plasma and inflammatory fluid were 96.7 μg · h/ml (SD, 10.3 μg · h/ml) and 77.9 μg · h/ml (SD, 19.2 μg · h/ml), respectively.
