big misconception that generics vary by as much as 20% from brand-name drugs
July 2008
There is a big misconception that generics vary by as much as 20% from brand-name drugs.
Some take this to mean that the amount of drug in the PRODUCT can vary by 20%...others think it refers to the amount of drug ABSORBED.
These assumptions are wrong. Generics must have the same amount of active drug as the brand...and the difference in bioavailability between most bioequivalent products is minimal.
