Sorry for the late response, I have been out of pocket the last few weeks. Yes, I asked both a respiratory therapist and a pharmacist that was speaking to our group and both had the same answer: the effective dosage is based on the form, and is determined by studies, so the dosage for one form is based on what the studies show is the effective dose for that form. You can’t compare dosages of different forms as it is apples to oranges given the difference in form.
