The pharmacokinetics of CP-409,092 following single intravenous and oral doses of 4 and 15 mg/kg, respectively, are characterized by high clearance of 169+ or -18 mL/min/kg, a volume of distribution of 8.99+ or -1.46 L/kg, and an oral bioavailability of 2.9%+ or -3%. Following oral administration of 100 mg/kg [14C]CP-409,092, the total recovery is 89.1%+ or -3.2% for male rats and 89.3%+ or -0.58% for female rats[1].
