description: This profile represents the constraints applied to the MedicationStatement resource by the PS-CA project to represent a record of a medication statement in the patient summary. It is informed by the constraints of the [MedicationStatement IPS-UV profile](http://hl7.org/fhir/uv/ips/StructureDefinition-MedicationStatement-uv-ips.html) and the [Canadian Baseline Profile](http://build.fhir.org/ig/HL7-Canada/ca-baseline/branches/master/StructureDefinition-profile-medicationstatement.html) to allow for cross-border and cross-jurisdiction sharing of Medication Summary information.
