Angiotensin II, the principal pressor agent of the renin-angiotensin system, is formed from angiotensin I in a reaction catalyzed by angiotensin-converting enzyme [kininase II]. It is responsible for effects such as vasoconstriction, stimulation of synthesis and release of aldosterone, cardiac stimulation, and renal reabsorption of sodium. Eprosart...

Angiotensin II, the principal pressor agent of the renin-angiotensin system, is formed from angiotensin I in a reaction catalyzed by angiotensin-converting enzyme [kininase II]. It is responsible for effects such as vasoconstriction, stimulation of synthesis and release of aldosterone, cardiac stimulation, and renal reabsorption of sodium. Eprosartan selectively blocks the binding of angiotensin II to the AT₁ receptor, which in turn leads to multiple effects including vasodilation, a reduction in the secretion of vasopressin, and reduction in the production and secretion of aldosterone. The resulting effect is a decrease in blood pressure.

Eprosartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT₁ receptor found in many tissues (e.g., vascular smooth muscle, adrenal gland). There is also an AT₂ receptor found in many tissues but it is not known to be associated with cardiovascular homeostasis. Eprosartan does not exhibit any partial agonist activity at the AT₁ receptor. Its affinity for the AT₁ receptor is 1,000 times greater than for the AT₂ receptor. In vitro binding studies indicate that eprosartan is a reversible, competitive inhibitor of the AT₁ receptor. Eprosartan has also been shown to bind to AT₁ receptors both presynaptically and synaptically. Its action on presynaptic AT₁ receptors results in the inhibition of sympathetically stimulated noradrenaline release. Unlike ACE inhibitors, eprosartan and other ARBs do not interfere with response to bradykinins and substance P, which allows for the absence of adverse effects that are present in ACE inhibitors (eg. dry cough).
