ATC Class Index
This is the top level index of the World Health Organization's
Anatomic Therapeutic Chemical classification system.
Browsing through this you will find drugs from the Health Canada database
that have been classified using the ATC system. If you find an empty class it may
mean there is no Health Canada drug in this class or perhaps the drug has been classified
elsewhere within the ATC system.
(In 2022 Medi-Mouse switched to the ATC system because
the American Hospital Formulary System (AHFS) classifications were no longer available
from the Health Canada database.)
