Pristiq release date?

When was Pristiq (desvenlafaxine) first approved and released?

Pristiq’s first FDA approval date was January 17, 2008. [1]

What does “release date” usually mean for a drug like Pristiq?

People sometimes use “release date” to mean one of three things:
- FDA approval date (the product is approved to be marketed)
- Launch/availability date (when wholesalers and pharmacies can fill prescriptions)
- Generic entry or exclusivity/patent timeline (when the brand’s market exclusivity ends)

For Pristiq, the best-documented “release date” is the FDA approval date: January 17, 2008. [1]

Is Pristiq still under brand exclusivity?
