Why don't medical practices of a decent size have on-site pharmacies that dispense the simple stuff? It seems to me that most of what a family practice prescribes is anti-biotics, why don't they just dispense that stuff themselves? More exotic and problematic drugs (like narcotics) can be left to the big pharmacies, but it would seem a fairly simple thing to dispense the other stuff.
But as an economist, I figure there must be a reason since it doesn't happen - either with the economics or with the regulation - so what is it? Anyone know?
