Represents a saleable unit of a medicinal product. This unit will typically (but not necessarily) contain a number of doses of medicine in one package, e.g., a 30 tablet bottle, a 20 ml tube. This class exists because different size containers will have different inventory codes and it is the packaged product that is generally associated with the manufacturing lot in which it was produced. For example, a 30 count bottle will have a different NDC than a 60 count bottle. Also, for manufacturing practicalities, the manufacturing lot and expiration date are on the bottle, not on each tablet. "A product in a container, or package. Represents the entirety of a product that has been packaged in a container for sale or supply; this representation of the Packaged Medicine may be in its real or actual form as something made, or described more conceptually, generically, or virtually, but it must represent a product contained in a package." - HL7 V3 Note that an important difference exists between the FHIM Packaged Medicinal Product and the nascent FHIR Medication.Package construct in that the FHIM does not adequately describe those situations where one has more than one drug form in the same package. For example, a package that has both an injectable liquid and a lotion. The FHIR Medication.Package appears to separate the contents better. The FHIM may in the future incorporate a separation of the drug forms into separate classes.
