Q. How can I determine whether the versions of a drug produced by different manufacturers are considered therapeutically equivalent?


The FDA produces an online resource called the "Orange Book."  To get a list of the various forms of a drug that have been tested for therapeutic equivalence, search by active ingredient using the generic name of the drug of interest.  Read the TE code definitions carefully before interpreting information rom the Orange Book.  As of 07/03/12, the code definitions can be found about half way down the webpage located via the links below (TE Code definitions)
