To get a drug approved you have to go through regulatory approval for a particular use. If the fuck-fuck game is you can just off-label for whatever but only if first approved by the FDA to solve some other problem, why not just bypass the bullshit and get straight to the point of approving the drug without any approved use? Oh yes, because that assures the barriers to entry are arbitrarily higher, and Pfizer and other ilk can insulate themselves from competition. Thanks FDA!
