Though that raises an interesting point, folk who rely on prescription medication are told to carry it in their hand luggage so it is accesable at all times, but are then told to leave it behind in the event of an emergency when some might just need it most or certainly afterwards.
Erm .....
Surely in the event of an emergency requiring the whole nine yards, slides 'n' all, there would be more than enough medical personnel available on the ground to triage those in need to medical assistance from those who don't.
So your "interesting point" is somewhat moot I would suggest.
