Title: "Medication Request Profile for Bangladesh"
Description: """
Profile of the MedicationRequest resource for the Bangladesh National Health
Information Exchange (HIE). Prescriptions must reference a BDMedication
resource coded against the DGDA Drug Registry, ensuring all prescribed
medications are traceable to DGDA-registered drug products.

This profile constrains medication references to BDMedication only.
Inline medicationCodeableConcept is not permitted — all medication data
must be carried in a referenced BDMedication resource to support ingredient
coding for IPS and cross-border data exchange.

Route of administration is coded using HL7 v3 RouteOfAdministration served
via the national OCL terminology server.
