# EHDSMedicationUse → MedicationStatement

### EHDSMedicationUse → MedicationStatement

 This page explains how conceptual elements from the EHDS logical model are expressed in the corresponding FHIR MedicationStatement profile used by this Implementation Guide. 

**Mapping Context**
*  **Source logical model:** [ EHDSMedicationUse ](https://www.xt-ehr.eu/fhir/models/0.3.0/StructureDefinition-EHDSMedicationUse.html) 
*  **Target FHIR profile:** [ MedicationStatementEuEps ](StructureDefinition-medicationStatement-eu-eps.md)
