Diovan is an angiotensin II receptor antagonist, a new class of blood pressure medications. It works by preventing the angiotensin II hormone from constricting the blood vessels, which usually raises blood pressure. It begins working within 2 hours; and maximum effect is achieved between 6 and 24 hours. Generally considered to be safer than other antihypertensives.
