Have had no luck with an imprint of APO / 960...
but if you take a look at the Apotex website at apotexcorp.com, you will see a list of all Aprotex products and imprint codes.
Doxazosin Mesylate Tablets 8mg have the following description:
Color: White
Imprint: APO, Rev. Side 096
Generic for:
Cardura
There is also an image available.
Hope this helps.
