摘要

The pharmacokinetics of otamixaban was investigated in healthy male subjects over a wide range of intravenous doses, with duration of administration varying between 1-minute infusions (bolus dose) and 24-hour infusions, using noncompartmental and multicompartmental methods. A global compartmental analysis (2 and 3 compartments) generated a single set of pharmacokinetic parameters, regardless of infusion rate and duration, and took into account the 30% decrease in clearance and volume of distribution observed over the dose range. The 2-compartment model was retained to predict bolus plus 3-hour-infusion doses of otamixaban for future phase (2/3) studies. Otamixaban exhibited in healthy subjects several interesting pharmacokinetic features in view of its potential therapeutic use in coronary thrombosis: a rapid plasma distribution and elimination, a well-described dose-exposure relationship, a low intersubject variability in plasma exposure, and a mixed renal and biliary excretion with constant renal clearance.
