I’m talking about desvenlafaxine or to give it its bright shiny new marketing name – Pristiq. CL Psych writes:
“Pristiq is Wyeth’s attempt to cover up for their bestseller Effexor coming off patent in the near future. Coverup? Considering that desvenlafaxine is a clear knockoff of Effexor (venlafaxine), yes, I’m sticking with that descriptor. Why do research to develop an innovative medication when you can just sell one that is quite highly similar to the one that is already a sales blockbuster?
The idea is not new – make a drug that very closely resembles your existing product, then get it FDA-approved slightly before the old one goes off patent. Lexapro-Celexa, Invega-Risperdal, and now Effexor-Pristiq. The new drug offers no advantage over the drug that is about to go generic…”
How do they get away with this kind of thing?
