Identify Rx and OTC products

GET /api/drug-sources/fdb/medications returns a FHIR Bundle of MedicationKnowledge resources. Each result can include an FDB Federal Legend Code at regulatory[0].schedule[0].schedule. Its text describes the class, and coding[0].code contains the FDB code.

The endpoint returns these FDB codes:

Code	Description	Meaning
1	Prescription Required	The product requires a prescription under the Food, Drug, and Cosmetic Act.
2	No Prescription Required	The product does not require a prescription under the Food, Drug, and Cosmetic Act.
3	Available in Multiple Classes	The packaged drugs associated with the medication have different values.
4	Non-drug, Non-device	The product is not a drug or device under the Food, Drug, and Cosmetic Act.
9	No Value	FDB has no packaged drug record associated with the medication.

For a drug, code 1 means Rx and code 2 means OTC. Codes 3, 4 and 9 do not establish an Rx or OTC class.
