That is a 100% incorrect statement that does not align with reality. FDA approval is certainly not all that counts—there is a mountain of other relevant considerations from a clinician’s point of view, patient’s point of view, and from an investor’s point of view. FDA has approved drugs that were only briefly commercialized or that never reached the market at all. Furthermore, there is an endless list of FDA approved drugs and devices that were bumped out of the market by safer, more efficacious, and more patient-friendly new technologies.
If you reread your statement, I’m sure you will agree that it really does not make sense in the context of the evolution of technologies and the free market.
