   * Valid Concepts for the drug_concept_id field belong to the "Drug" domain. Most Concepts in the Drug domain are based on RxNorm, but some may come from other sources. Concepts are members of the Clinical Drug or Pack, Branded Drug or Pack, Drug Component or Ingredient classes.
   * Source drug identifiers, including NDC codes, Generic Product Identifiers, etc. are mapped to Standard Drug Concepts in the Standardized Vocabularies (e.g., based on RxNorm). When the Drug Source Value of the code cannot be translated into standard Drug Concept IDs, a Drug exposure entry is stored with only the corresponding source_concept_id and drug_source_value and a drug_concept_id of 0.
-  * The Drug Concept with the most detailed content of information is preferred during the mapping process. These are indicated in the concept_class_id field of the Concept and are recorded in the following order of precedence: "Branded Pack", "Clinical Pack", "Branded Drug", "Clinical Drug", "Branded Drug Component", "Clinical Drug Component", "Branded Drug Form", "Clinical Drug Form", and only if no other information is available "Ingredient". Note: If only the drug class is known, the drug_concept_id should contain 0.

These are indicated in the concept_class_id field of the Concept and are recorded in the following order of precedence: "Marketed Product", "Branded Pack", "Clinical Pack", "Branded Drug", "Clinical Drug", "Branded Drug Component", "Clinical Drug Component", "Branded Drug Form", "Clinical Drug Form", and only if no other information is available "Ingredient". Note: If only the drug class (i.e. "Diuretic", "NSAID") is known, the drug_concept_id should contain 0.
   * A Drug Type is assigned to each Drug Exposure to track from what source the information was drawn or inferred from. The valid domain_id for these Concepts is "Drug Type".
   * The content of the refills field determines the current number of refills, not the number of remaining refills. For example, for a drug prescription with 2 refills, the content of this field for the 3 Drug Exposure events are null, 1 and 2.
