For many antidepressants, the issue of brand-name versus generic has no practical significance. Elavil was first marketed almost a half century ago, and its patent has long expired. It lives on, however, but as generic amitriptyline. Today, only a few antidepressants are still fully protected by patents, namely, Cymbalta (2010), Lexapro (2012), and Pristiq (2022) for major depressive disorder (MDD); and Seroquel (2011) and Symbyax (2017) for bipolar depression.
