Reporting Limit determined each analysis.
Units: ng/mL
Bupropion:
Maximum antidepressant response was observed at trough plasma concentrations of 50 – 100 ng/mL bupropion with virtually no response below 25 ng/mL.
Reported average bupropion peak plasma concentrations:
Adults: Single 100 mg IR – 120 +/- 10 ng/mL (Males):
150 +/- 10 ng/mL (Females)
Adults: Single 200 mg IR -220 +/- 20 ng/mL (Males):
270 +/- 20 ng/mL (Females)
Adults: Single 150 mg SR - 140 +/- 20 ng/mL
Juveniles: 100 mg/day SR for 2 weeks – 25 +/- 8 ng/mL
Juveniles: 200 mg/day SR for 2 weeks – 53 +/- 22 ng/mL
Specimens must be kept frozen. If specimens are not kept frozen, this may cause lower or negative values.
Hydroxybupropion:
8 adults (Age 22 – 42) taking thrice daily 100 mg normal release bupropion for 2 weeks had an average peak plasma concentration of 1000 +/- 70 ng/mL hydroxybupropion.
Juvenile patients taking once daily, extended release bupropion for two weeks had the following peak plasma concentrations:
100 mg/day (n = 11), 450 +/- 210 ng/mL hydroxybupropion
200 mg/day (n = 8), 710 +/- 350 ng/mL hydroxybupropion
