What Is Olmesartan 5mg?
Olmesartan is a prescription blood pressure medicine in the ARB (angiotensin II receptor blocker) class. It works by blocking a hormone that narrows blood vessels, helping vessels relax so blood pressure comes down. Lowering blood pressure reduces the risk of cardiovascular events such as stroke and heart attack. Many patients search for amlodipine-olmesartan or olmesartan amlodipine HCTZ combinations; olmesartan can be taken alone or combined with these medicines when one drug is not enough.
