Olmin(Olmesartan) is used to treat high blood pressure (hypertension), prevention and treatment of heart attack (Myocardial Infarction) and heart failure; when heart is unable to pump sufficient blood. It is also used in patients of diabetes with kidney failure.
Olmesartan belongs to a class of medications called angiotensin II receptor inhibitors. Angiotensin II is a chemical that causes muscles surrounding the blood vessels to contract, thereby narrowing the blood vessels. Olmesartan blocks the action of angiotensin II resulting in relaxation of blood vessels, and thus, reduces blood pressure.
