title: Current status of angiotensin receptor blockers for the treatment of cardiovascular diseases: focus on telmisartan.
abstract: Poorly controlled hypertension is a major risk for cardiovascular morbidity and mortality, strokes, heart failure and renal failure. Despite these devastating complications, blood pressure control of </=140/90 mmHg, which is above the current standard, is very poor worldwide, accounting for 34% of hypertensive patients in the United States, and 6% in other countries. The reasons for this poor control of blood pressure include lack of aggressive treatment by physicians, especially for the systolic blood pressure, drug selection and patient compliance. The blood pressure follows a circadian rhythm and is the highest between 0600 to 1200 h, when most complications occur. Long-acting drugs that extend their action to cover this vulnerable period are preferable, especially those that block the renin-angiotensin-aldosterone system, such as ACE inhibitors and angiotensin receptor blockers, and are the most effective in controlling blood pressure and preventing or reducing its cardiovascular and renal complications. With respect to the angiotensin receptor blockers, telmisartan has been demonstrated by several studies to be the longest acting among its class of drugs and to effectively prevent the early morning rise of blood pressure.
