Every time the human heart beats, it pumps blood to the whole body through the arteries. Blood pressure is the force of blood pushing up against the blood vessel ...
Endothelin receptor antagonists, by blocking the vasoconstrictor and cardiotonic effects of ET-1, produce vasodilation and cardiac inhibition. Endothelin receptor antagonists have been shown to decrease mortality and improve hemodynamics in experimental models of heart failure. At present, the one ...
Alpha-adrenoceptor agonists (α-agonists) bind to α-receptors on vascular smooth muscle and induce smooth contraction and vasoconstriction, thus mimicking the effects of sympathetic adrenergic nerve activation to the blood vessels. Examples: clonidine, guanabenz, guanfacine, methyldopa, ...
Aldosterone receptor antagonists are medicines that help the body get rid of extra water (diuretics). They also have other properties that can prevent heart failure from becoming worse, along with improving symptoms of heart failure. These medicines cause the kidneys to get rid of extra water and ...
Renin inhibitors produce vasodilation by inhibiting the activity of renin, which is responsible for stimulating angiotensin II formation. Renin is a proteolytic enzyme that is released by the kidneys in response to sympathetic activation, hypotension, and decreased sodium delivery to the distal ...
