What is amlodipine and olmesartan?
Amlodipine is a calcium channel blocker. It works by relaxing the muscles of your heart and blood vessels.
Olmesartan is an angiotensin II receptor antagonist. Olmesartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.
Amlodipine and olmesartan may also be used for purposes not listed in this medication guide.
