Generic drugs, both over-the-counter and prescription medications, are very strictly regulated by the Food and Drug Administration’s (FDA) rules for generics. Regulations include:
· A generic’s active ingredient, dosage, and strength must be the same as its brand-name equivalent.
· Generic drugs must be "bioequivalent" to brand-name drugs, meaning they have to show up as the same in the bloodstream and work in the exact same way.
· Manufacturing, testing, and packaging sites are subject to the same FDA regulations, whether the product in question is a brand name or a generic. (About half of generic drugs are actually made by the same companies making the brand-name versions.)
In the end, the variation in performance between brand names and generics is about the same as the variation between brands.
So, do Doctors buy generic?
