Implementation Reference

• src/mapping-service.ts:174-207 (handler)

  The handler function that executes the logic to retrieve RxNorm mappings by pharmacologic class.

  getRxNormMappingsByPharmacologicClass(pharmaSetId: string): {
    pharmaSetId: string;
    splSetIds: string[];
    rxNormMappings: RxNormMapping[];
    fdaContext: {
      definition: string;
      explanation: string;
      classification: string[];
    };
  } {
    const splSetIds = this.pharmaSetIdToSplSetIds.get(pharmaSetId) || [];
    const allRxNormMappings: RxNormMapping[] = [];
    
    for (const splSetId of splSetIds) {
      const rxNormMappings = this.getRxNormMappings(splSetId);
      allRxNormMappings.push(...rxNormMappings);
    }
    
    return {
      pharmaSetId,
      splSetIds,
      rxNormMappings: allRxNormMappings,
      fdaContext: {
        definition: "A pharmacologic class is a group of active moieties that share scientifically documented properties",
        explanation: "According to FDA guidelines, pharmacologic classes provide clinically meaningful and scientifically valid drug classifications based on three key attributes: Mechanism of Action (MOA), Physiologic Effect (PE), and Chemical Structure (CS)",
        classification: [
          "Mechanism of Action (MOA): How the drug works at the molecular level",
          "Physiologic Effect (PE): The body's response to the drug",
          "Chemical Structure (CS): Structural characteristics of the active moiety",
          "Source: National Drug File Reference Terminology (NDF-RT)"
        ]
      }
    };
  }
