No big deal.
Switching from losartan to candesartan in a systematic manner with a careful follow up was not only cost effective but achieved a significant fall in blood pressure providing effective prescribing and improved patient
This I think was the conclusion of a pilot study in Hertfordshire I think.....also Candersarten is cheaper than Losarten.
Both act in the same way and are both Angiotensin 2 receptor antagonists............so...........no big deal.
BUT...if my BP was stabilised with Candersarten I would need to have a bloody good reason for the doctor changing them......anf personally I don't think that the results of that pilot study would be good enough reason.
My advice.....if you have any Candesarten left then tkae them until Monday and then put your concerns to your doctor, but if you haven't, then bite the bullet and take your new Losarten tablets until Monday.
