Thanks for posting your query.
Benicar and Cozaar both drugs are of same class of anti-hypertensive.Benicar contains olmesartan
and cozaar contains losartan .Both of them are Angiotensin
Mechanism of action and side effects of both the drugs are similar hence there will not be any added benefit of changing from one to another. It is the cost and availability that matters for choosing one.
is a angiotensin converting enzyme inhibitor which increases bradykinin levels in lungs and blood which causes chronic dry cough.Because of this reason your had changed lisinopril to benicar or cozaar.
Benicar and Cozaar both has same efficacy for hypertension
.So continue the same drug (cozaar) that your doctor has advised and maintain blood pressure below 120/80 m of Hg.
Hope this could help you better.
Wish you good health.
