Creating sophisticated compounds to treat complex diseases is fraught with risk. Moving from a clinical trial involving hundreds/thousands, to a commercialized product that is used by millions, is going to cause some unfortunate side effects.....human physiology being so different and all.
It is what it is. Trying to eliminate this risk will only kill innovation. And I don't know if you're paying attention to the problems we're facing with treating infections, but this isn't a time to be circling the wagons.
Innovation for what? Managing symptoms mostly is all these drugs do! Living longer is not the end all. Finding the did ease in our spirit is the answer. Fhu.com has that pathway.
