Six healthy elderly male and six healthy elderly female subjects (Sub) completed a three period, fixed sequence, single rising dose (200mg, 400mg, 800mg) study of Drug A. A seven day washout period separated each of the single dose administrations of Drug A.
On each of the single dosing days, blood samples were taken from each of the subjects just prior to dosing and at 1, 2, 4, 6, 8, 12, 24, 30, 48, 60, and 72 hours post dose, and then assayed for plasma levels of Drug A. From these assay values, the area-under-the-plasma-concentration-vs.-time curve, AUC (ng·hr/mL), from time 0 hours to infinity, and the maximum plasma concentration, Cmax (ng/mL), were calculated for Drug A, for each subject, in each fixed sequence, rising single dose, treatment period.
