Primary Outcome Measures
NameTimeMethod
Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - 8)]0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48

AUC (0 - 8)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - 8). It is obtained from AUC (0 - t) plus AUC (t - 8).

Maximum Observed Plasma Concentration (Cmax)0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48
Secondary Outcome Measures
NameTimeMethod
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48

Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)

Plasma Decay Half-Life (t1/2)0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48

Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

Concentration at time 24 hours (C24)0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48
Time to Reach Maximum Observed Plasma Concentration (Tmax)0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48
