GlaxoSmithKline plc

Drug Names(s): Bupropion hydrochloride immediate release (IR)/sustained-release (SR)

Description: Biomedtracker has a separate entry for Wellbutrin XL.

Wellbutrin has three formulations: immediate release (three times daily), sustained released (SR, twice daily), and extended release (XL, once-daily).

Wellbutrin is an antidepressant that inhibits the reuptake of dopamine, norephinephrine, and to some extent serotonin. Its effect on dopamine is the most potent, but in actuality, it is a fairly weak reuptake blocker of all three of these, and its mechanism of action is not clear.

Deal Structure: All historical revenue for Wellbutrin is recorded under Wellbutrin/SR.
