Transform to ATC code

Use this function to determine the ATC code of one or more antibiotics. The data set antibiotics will be searched for abbreviations, official names and trade names.

as.atc(x)

is.atc(x)

Arguments

x	character vector to determine ATC code

Value

Character (vector) with class "act". Unknown values will return NA.

Details

Use the ab_property functions to get properties based on the returned ATC code, see Examples.

In the ATC classification system, the active substances are classified in a hierarchy with five different levels. The system has fourteen main anatomical/pharmacological groups or 1st levels. Each ATC main group is divided into 2nd levels which could be either pharmacological or therapeutic groups. The 3rd and 4th levels are chemical, pharmacological or therapeutic subgroups and the 5th level is the chemical substance. The 2nd, 3rd and 4th levels are often used to identify pharmacological subgroups when that is considered more appropriate than therapeutic or chemical subgroups.

WHOCC

This package contains all ~500 antimicrobial drugs and their Anatomical Therapeutic Chemical (ATC) codes, ATC groups and Defined Daily Dose (DDD) from the World Health Organization Collaborating Centre for Drug Statistics Methodology (WHOCC, https://www.whocc.no) and the Pharmaceuticals Community Register of the European Commission (http://ec.europa.eu/health/documents/community-register/html/atc.htm).

These have become the gold standard for international drug utilisation monitoring and research.

The WHOCC is located in Oslo at the Norwegian Institute of Public Health and funded by the Norwegian government. The European Commission is the executive of the European Union and promotes its general interest.

Examples

# NOT RUN {
# These examples all return "J01FA01", the ATC code of Erythromycin:
as.atc("J01FA01")
as.atc("Erythromycin")
as.atc("eryt")
as.atc("   eryt 123")
as.atc("ERYT")
as.atc("ERY")
as.atc("Erythrocin") # Trade name
as.atc("Eryzole")    # Trade name
as.atc("Pediamycin") # Trade name

# Use ab_* functions to get a specific property based on an ATC code
Cipro <- as.atc("cipro") # returns `J01MA02`
atc_official(Cipro)      # returns "Ciprofloxacin"
atc_umcg(Cipro)          # returns "CIPR", the code used in the UMCG
# }
