Get U.S National Drug Code(NDC) via Semantic Branded Drug(SBD) or Semantic Clinical Drug(SCD) RxCui

Source: R/funPharm.R, R/getNDCViaSBDRxCui.R

This function provides user tO get U.S National Drug Code(NDC) via Semantic Branded Drug(SBD) RxCui or Semantic Clinical Drug(SCD) RxCui contained these drug ingredients.

getNDCViaSBDRxCui(df, SBDRxCuiColName = SBD.rxcui, cores = 8)

Arguments

df

data.frame, a drug ingredient SBD or SCD RxCui of the specific indication
cores

number of parallel operation
RxCuiColName

a column name for RxCui of df

Value

A new data.table maytreat_NDC_List with following columns.

RxCui drug RxCui

Name drug name

MinConcept.Id indication Id

MinConcept.Name indication name

SBD.rxcui drug SBD RxCui

NDC drug NDC

Details

User can screen out the patient who has the record of receiving these drugs in the medication data, but not all medication data are encoded in RxNorm. In the United States, for example, the drug code commonly used in medical data is NDC code. NDC code cannot be directly filtered with RxNorm coded data. Therefore, user can input the data.frame from getRxCuiViaMayTreat(), then convert to NDC code and screen out a new data.frame.

However, a drug will have different packaging and NDC because it comes from different pharmaceutical brands. There will be different NDC for the same drug type but different packaging. Hence, the output results will be one-to-many. A drug RxCui will matche to multiple NDC of pharmaceutical brands, and no corresponding NDC will be NA.

Examples
