Can you define "how it is used" ?

1) GNUmed does not model bioavailability.

        no one knows how much of Ibuprofen 600mg actually enters
        the patient system

2) GNUmed is not a treatment planning system

        hence the "how it is used" turns into "how it was
        used" hence the dose can be known (if so desired)

3) Documenting Iodine 131 loading may be useful.

        documenting the exact dose in computable form may not be
        necessary and my be added in a comment field
