RESUMO
The objective of this Phase I study was to evaluate the safety, tolerance, and pharmacokinetics of BMY-28100 in 36 male subjects after the administration of single oral doses of 250, 500, and 1,000 mg. The subjects were divided into groups of 12 per dose group. All subjects completed the study, and BMY-28100 was well tolerated at all doses. The maximum concentration of the drug in plasma ranged from 6.2 to 17.7 micrograms/ml for the 250- and 1,000-mg doses, respectively, and the area under the curve increased in a dose-proportional manner. The elimination half-life and renal clearance averages were 1.2 h and 200 ml/min, respectively. The values for renal clearance suggest that BMY-28100 is excreted by glomerular filtration and tubular secretion. Mean concentrations of the drug in urine were highest during the first 4 h after the doses and ranged from 175 to 658 micrograms/ml following the 250- and 1,000-mg doses, respectively. The mean urinary recovery ranged from 57 to 70% of the dose. The results from this Phase I study indicate that BMY-28100 is well tolerated and exhibits linear pharmacokinetics.
