Pharmaceutical equivalence determined by comparison of the relative potency of the generic products against the innovator. Relative potency at the linear regression midpoint (mean and 95% CI) of the innovator and generic products of amikacin (2A), gentamicin (2B) and vancomycin (2C). Except for vancomycin Abbott, there were no significant differences in potency between generics and their corresponding innovator, confirming pharmaceutical equivalence.
