7. bioequivalence [study](English)

   • when two formulations of the same drug or two drug products are claimed bioequivalent, it is assumed that they will provide the same therapeutic effect or that they are therapeutically equivalent. In this case, most people interpret that they can be used interchangeably. Two drug products are considered pharmaceutical equivalents if they contain identical amounts of the same active ingredient. Two drugs are identified as pharmaceutical alternatives to each other if both contain an identical therapeutic moiety, but not necessarily in the same amount or dosage form or as the same salt or ester. Two drug products are said to be bioequivalent if they are pharmaceutical equivalents (i.e., similar dosage forms made, perhaps, by different manufacturers) or pharmaceutical alternatives (i.e., different dosage forms) and if their rates and extents of absorption do not show a significant difference to which the active ingredient or active moiety in pharmaceutical equivalents or pharmaceutical alternatives become available at the site of action when administered at the same molar dose under similar conditions in an appropriately designed study
