description: The Anatomical Therapeutic Chemical (ATC) classification system, divides
  active substances into different groups according to the organ or system on which
  they act and their therapeutic, pharmacological and chemical properties. Drugs are
  classified in groups at five different levels;  Drugs are divided into fourteen
  main groups (1st level), with pharmacological/therapeutic subgroups (2nd level).  The
  3rd and 4th levels are chemical/pharmacological/therapeutic subgroups and the 5th
  level is the chemical substance. The Anatomical Therapeutic Chemical (ATC) classification
  system and the Defined Daily Dose (DDD) is a tool for exchanging and comparing data
  on drug use at international, national or local levels.
