Study Endpoints
Primary Endpoints
The Area Under the Plasma Concentration [AUC] Versus Time Curve Calculated From Time Zero to the Last Measurable Sampling Time Point (Tlast) (AUC [0-tlast])
Pre-dose (-1 hour) and 0.08, 0.17, 0.33, 0.5, 0.67, 0.83, 1, 1.33, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 14, 16 hours Post dose.

Blood samples were collected at the indicated time points for the analysis of AUC (0-tlast). Pharmacokinetic (PK) parameters were calculated by standard non-compartmental analysis.

The Time of the Maximum Observed Post-dose Concentration (Tmax)
Pre-dose (-1 hour) and 0.08, 0.17, 0.33, 0.5, 0.67, 0.83, 1, 1.33, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 14, 16 hours Post dose.

Blood samples were collected at the indicated time points for for the analysis of tmax. PK parameters were calculated by standard non-compartmental analysis.

The Maximum Observed Post-dose Concentration (Cmax)
Pre-dose (-1 hour) and 0.08, 0.17, 0.33, 0.5, 0.67, 0.83, 1, 1.33, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 14, 16 hours Post dose.

Blood samples were collected at the indicated time points for for the analysis of Cmax. PK parameters were calculated by standard non-compartmental analysis.

Secondary Endpoints
Area Under the Plasma Concentration Versus Time Curve Calculated From Time Zero to Infinity [AUC (0-inf)]
Pre-dose (-1 hour) and 0.08, 0.17, 0.33, 0.5, 0.67, 0.83, 1, 1.33, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 14, 16 hours Post dose.
Percentage of AUC (0-inf) Obtained by Extrapolation (%AUCex)
Pre-dose (-1 hour) and 0.08, 0.17, 0.33, 0.5, 0.67, 0.83, 1, 1.33, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 14, 16 hours Post dose.
Terminal Elimination Rate Constant (λz)
Pre-dose (-1 hour) and 0.08, 0.17, 0.33, 0.5, 0.67, 0.83, 1, 1.33, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 14, 16 hours Post Dose.
