Fda orange book glumetza glucophage xr therapeutic equivalence code?

In the FDA Orange Book the therapeutic equivalence code for both Glumetza (metformin XR) and Glucophage XR (generic metformin XR) is “TE 1.”

• TE 1 means that the generic product is considered therapeutically equivalent to the reference listed drug (RLD) in terms of active ingredient, dosage form, strength, and intended use.

So regardless of whether you’re looking at the brand‑name Glumetza or the generic Glucophage XR, the Orange Book lists each entry with the same TE 1 designation.
