Retrospective Database Analysis to Explore Patterns and Economic Burden of Switchback to Brand After Generic or Authorized Generic Utilization.

Patients receiving a brand medication are likely to be switched to a generic upon market availability.

Additional research is needed to understand switching, its potential disruption to patients, and the role of brands, generics, and AGs.
