We want to capture two dosages for a medication, let's say Ampicillin. First, the "absolute" dosage: of a 250 mg powder vial, the patient needs only 150 mg. But this is not actionable in our context; the entire vial of ampicillin gets mixed with 1.3ml sterile water to achieve a concentration of 250 mg/1.5 ml. The actionable/mixed dosage is the amount of this mixture that should be administered, 0.9ml in this case. How could these two kinds of dosages be represented with FHIR Resources? Thank you!

This looks like 250 mg is the quantity dispensed and 150mg is the quantity administered, and the rest is how the administered dose is prepared.

I wouldn't consider both of these as "dosages". The 250mg powder vial is what is supplied as the product - this would be captured as part of the medication. The 150mg is the actual dose that is administered. This would be captured as part of the dosage instructions - either in the dispense or the administration.
