  2. In a way, this mini-test reminded me of other diabetes drugs. I was thinking of cozaar, but it seems it's not in the listing.

    1. Thanks for your comment. I do not usually think of Cozaar as a diabetes drug. Cozaar is one of the angiotensin receptor blockers available for the treatment of hypertension. Angiotension 2 constricts small arteries resulting in increased blood pressure. Cozaar interfers with angiotensin 2 's attachment to tissue receptors and helps lower blood pressure.
