description: The National Drug File (NDF) is produced by the U.S. Department of Veterans
  Affairs, Veterans Health Administration (VHA). NDF is a centrally maintained electronic
  drug list used by the VHA hospitals and clinics. Facilities use the NDF to check
  drug interactions, to manage orders, and to send outpatient prescriptions to regional
  automated mail-out pharmacies. NDF includes information on clinical drugs, drug
  classes, ingredients and National Drug Code (NDC) Directory codes.
