Eprosartan mesylate BiologicalActivity

Description	Eprosartan is a nonpeptide angiotensin II receptor antagonist with IC50 of 9.2 and 3.9 nM in rat and human adrenal cortical membranes, respectively. IC50 Value: 9.2 nM(in rat adrenal cortical membranes); 3.9 nM(in human adrenal cortical membranes)Target: Angiotensin Receptor Type-1(AT1)in vitro: Eprosartan mesylate, is one of the highly selective, orally active, non-peptide angiotensin-II-receptor antagonists [1]. In rat and human adrenal cortical membranes, Eprosartan displaced specifically bound [125I]AII with IC50 of 9.2 and 3.9 nM, respectively. Eprosartan also inhibited [125I]AII binding to human liver membranes (IC50 = 1.7 nM) and to rat mesenteric artery membranes (IC50 = 1.5 nM). In rabbit aortic smooth muscle cells, Eprosartan caused a concentration-dependent inhibition of AII-induced increases in intracellular Ca++ levels. In rabbit aortic rings [2].in vivo: Administration of Eprosartan (3-10 mg/kg) intraduodenally or intragastrically to conscious normotensive rats resulted in a dose-dependent inhibition of the pressor response to AII (250 ng/kg, i.v.). At 10 mg/kg, i.d., significant inhibition of the pressor response to AII was observed for 3 hr. In this same rat model, Eprosartan had no effect on base-line pressure or on the pressor response to norepinephrine or vasopressin [2]. Eprosartan is highly effective and safe in lowering blood pressure, notably SBP, in older subjects with mild to moderate hypertension [3]. Treatment with eprosartan in once-daily doses up to 1200 mg alone or in combination with HCTZ was well tolerated, with dizziness and asthenia being the most common side effects [4]. Therapy with eprosartan mesilat was associated with significant hypotensive effect (more evident in patients with high systolic blood pressure), improvement in 24-hour blood pressure profile and quality of life, and lower probability of secondary stroke. Side effects were not observed [5].
