I have said this before. most times the reason a given med is weaker is not due to active ingrediants but to the "manufacture" process. for example lets take baby powder. for the name brande they mill "grind" the raw pawder 7 times. brand x wants to save money so they mill it 5 times. thus they save money in the milling process but any parent can tell the differance in "cheap" baby powder as opposed to JJ brand. they same with meds. the more the process an active ingrediant the better it is absorbed. smaller particles. it can be any drug. the savings is in the processing shave a liilte here or a little there and it is chemiclly the same med but it is different in the way it was made.
PM if you want more examples
