What you will receive

Imdur is the originator brand name, made by AstraZeneca. We use it here to identify the medicine only; we are not affiliated with AstraZeneca and do not ship the original Imdur.

  • You receive a generic equivalent: the same active ingredient (Isosorbide Mononitrate) at the same dose, mostly recognised branded generics from vetted manufacturers.
  • The exact brand supplied depends on what is in stock at the dispatching warehouse.
  • Inactive ingredients, tablet appearance and packaging can differ from the original brand; the active ingredient and dose are the same.
