Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |

| Pharmacokinetic (PK) profile for bupropion (in plasma): AUCinf, AUClast, Cmax | Area under the concentration-time curve (AUC) from time 0 extrapolated to infinity (AUCinf), AUC from time of dosing to the last quantifiable concentration (AUClast), and maximum concentration(Cmax) | Day 1 at pre-dose and 0.5,1,1.5, 2, 3, 4, 6, 8, 10, 12, 16, 20, 24, 48, 72,and 96 hours post-dose and Day 15 at pre-dose and 0.5, 1, 1.5, 2, 3, 4, 6, 8,10,12,16, 20, 24, 48, 72, 96,120, and 144 hours post-dose | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| PK profile for bupropion (in plasma): t1/2, tmax, CL/F, and Vz/F | Apparent terminal elimination half-life (t1/2), Time to attain Cmax (tmax), Apparent body clearance after oral dosing (CL/F), and apparent volume of distribution (Vz/F) | Day 1 at pre-dose and 0.5,1,1.5, 2, 3, 4, 6, 8, 10, 12, 16, 20, 24, 48, 72,and 96 hours post-dose and Day 15 at pre-dose and 0.5, 1, 1.5, 2, 3, 4, 6, 8,10,12,16, 20, 24, 48, 72, 96,120, and 144 hours post-dose |
