title: Endothelin-receptor antagonists in arterial hypertension: further indications?
abstract: Endothelin-1 exerts vasoactive, pro-inflammatory, hypertrophic, and profibrotic properties on the heart, kidney, and blood vessels. Hence, endothelin-receptor antagonists hold the potential to reduce blood pressure and to prevent complications of hypertension, atherosclerosis, and diabetes through blood pressure-independent effects on cardiovascular growth, inflammation, and fibrosis. These potentially important effects of endothelin antagonism may contribute to its therapeutic potential in hypertension and other cardiovascular disorders, including chronic renal failure and diabetes. First clinical trial evidence demonstrates a moderate reduction in blood pressure in studies of patients with mild-to-moderate essential hypertension and patients with resistant hypertension. Future large-scale randomized clinical trials will provide more insight into whether the blood-pressure reduction and promising pleiotropic effects observed with several members of this novel class of drugs, which are already established therapy in pulmonary hypertension, will translate into clinical benefit in patients with arterial hypertension.
