The second line drug, Memantine (#N06DX01), has been classified in Prescribing in Taiwan under another group
Other antidementia drugs (#N06DX),
but this group also includes another drug Ginkgo folium (#N06DX02). They are grouped without we knowing the fact that Ginkgo folium has been precribed for
peripheral artery diseases.
The relatively high prescribing rates and the age distribution of this ATC drug group could be the mix between Ginkgo folium and Memanatin.
This is labelled as one of the hindsights and the two drugs will be treated separately when there is an update of Precribing in Taiwan.
