All of the following are conditions for a medication to be considered therapeutically equivalent, EXCEPT _________.

The correct answer is "Can be administered by an approved route." This is because the route of administration is a condition for a medication to be considered therapeutically equivalent. Therapeutically equivalent medications must have the same active ingredient, same dosage form, and same strength or concentration. However, they do not necessarily have to be administered by the same route. Different routes of administration may be suitable for the same medication depending on the patient's needs and the specific formulation available.
