It's really a form of regulatory capture and goes way beyond drugs into medical devices, IT systems, etc. The "approved" thing is often a more expensive, less complete/reliable/modern version of something people who aren't subject to regulation can get off the shelf. You can think of it sort of like if car dealerships managed to get a law passed that said you can only service your car at the dealership, and then 10x'd their prices.
