When does Bupropion patent exclusivity expire?

Can generic Bupropion 150mg be manufactured?

How does Bupropion 150mg compare to other antidepressants?
Bupropion's mechanism of action, primarily affecting dopamine and norepinephrine rather than serotonin, differentiates it from many selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) [3]. This difference can make it a suitable option for individuals who do not respond well to or experience side effects from other antidepressant classes [3].
What is the typical pricing for Bupropion 150mg?
