Safety and efficacy of eprosartan, a new angiotensin II receptor blocker.

Angiotensin-converting enzyme inhibitors have been used extensively in the management of hypertension and related cardiovascular conditions. However, this treatment approach is limited by lack of specificity and continued production of angiotensin II by other routes. Antagonism of the angiotensin II receptor offers the possibility of improved control of hypertension by providing a more complete blockade of the renin-angiotensin system than angiotensin-converting enzyme inhibition without bradykinin-related effects. Eprosartan is the only nonbiphenyl, nontetrazole competitive angiotensin II receptor antagonist clinically available and is highly selective for the AT1 receptor subtype. In clinical trials, eprosartan has been shown to lower blood pressure effectively in a once-daily regimen in hypertensive patients. In the recommended dose range of 600 to 1200 mg once daily, eprosartan is effective in patients with all grades of hypertension irrespective of age, sex, or race. Furthermore, the tolerability profile of eprosartan is comparable to that of placebo, and there are no known clinically relevant drug-drug interactions. A number of large-scale clinical studies are currently underway or planned to determine which of the increasing number of AT1 receptor antagonists may reduce cardiovascular morbidity and mortality rates in different groups of hypertensive patients. Meanwhile, current evidence suggests that the AT1 receptor antagonists represent a significant new approach to cardiovascular therapy and merit a fuller assessment in hypertension and other cardiovascular diseases.
