# Medication Statement

> Schema documentation for the Medication Statement table in the Metriport data model

A medication statement record represents a record of a medication that is being consumed by a patient. This includes details about the medication, its current status, and any relevant clinical information.

**Reference Table:**

The `medication_statement_references` table contains normalized references from the medication statement to other entities. It supports the following reference properties:

* **medication\_reference** (required): links to the medication referenced in the statement
* **subject** (required): links to the patient who is taking the medication

For detailed information about reference table structure and indexing, see the [Reference Tables documentation](/medical-api/handling-data/schema-v000/reference-tables).

**Medication Statement Table:**

**Primary Keys:**

* medication\_statement\_id

**Foreign Keys:**

* patient\_id
* medication\_id
