http://hl7.org/fhir/StructureDefinition/MedicationRequest|4.0.1

An order or request for both supply of the medication and the instructions for administration of the medication to a patient. The resource is called \"MedicationRequest\" rather than \"MedicationPrescription\" or \"MedicationOrder\" to generalize the use across inpatient and outpatient settings, including care plans, etc., and to harmonize with workflow patterns.
