FHIR medication - hl7

Question

I have a data model for medications like this:
Drug name
Prescription Date
Preparation
Dose
Quantity
for example:
Bendroflumethiazide (Bendrofluazide), 05/12/2015, TABS 2.5MG,1 Tab,56
I had a look at the medication resource but I am unable to map it. Can anyone help me with this mapping?
Thanks.

Answer 1

Firstly I wanted to ask more details but I couldn't comment on your question because of stackverflow reputation system.
In FHIR, the Medication domain includes a number of related resources, they are;
MedicationOrder
MedicationDispense
MedicationAdministration
MedicationStatement
#brillox also refenced this but I will point this again Resource Medication - Content This source is like Master File Notification (MFN for HL7 v2)
Please check examples to see drug names. I also gave one example below.
For Medication Administration please check examples and descriptions, you will find all details you need. Resource MedicationAdministration - Detailed Descriptions
An example for compounded medication;

What is your data representing? I assume medication prescriptions by a physician.
You should look at the Medicationorder ressource:
https://www.hl7.org/fhir/medicationorder.html
There are many examples of doing it on the FHIR Homepage, like this one:
https://www.hl7.org/fhir/medicationorder-example-f001-combivent.xml.html
In the medication order resource you are then link to your actual Medication resource: https://www.hl7.org/fhir/medication.html
If you have medications from different prescribers or different start/end dates, just use one medication order per prescription.
