Summary: NDF-RT is an extension of the VHA National Drug File (NDF). It organizes the drug list into a formal representation. NDF-RT is used for modeling drug characteristics including ingredients, chemical structure, dose form, physiologic effect, mechanism of action, pharmacokinetics, and related diseases. NDF-RT combines the NDF hierarchical drug classification with a multi-category reference model. The categories are:
Cellular or Molecular Interactions [MoA]
Chemical Ingredients [Chemical/Ingredient]
Clinical Kinetics [PK]
Diseases, Manifestations or Physiologic States
[Disease/Finding]
Dose Forms [Dose Form]
Pharmaceutical Preparations
Physiological Effects [PE]
Therapeutic Categories [TC]
VA Drug Interactions [VA Drug Interaction]
