The renin-angiotensin system regulates blood pressure and sodium homeostasis through a series of coordinated substrate-enzyme interactions. These interactions result in the production of angiotensin II (AII), which exerts a number of diverse biologic effects mediated through AII cell-surface receptors. Dysregulation of this system is implicated in the pathogenesis of various forms of hypertension. Traditional therapy for hypertension has included angiotensin-converting enzyme inhibitors, which block the production of AII. However, a new class of drugs, AT1-receptor blockers, now offers a number of benefits by specifically blocking the effects of AII at its physiologically relevant receptor.
肾素-血管紧张素系统通过一系列协调的底物-酶相互作用来调节血压和钠平衡。这些相互作用导致血管紧张素II(AII)的产生,AII通过AII细胞表面受体介导多种不同的生物学效应。该系统的失调与各种形式高血压的发病机制有关。传统的高血压治疗方法包括使用血管紧张素转换酶抑制剂,这类药物可阻断AII的产生。然而,一类新型药物——AT1受体阻滞剂,通过特异性阻断AII在其生理相关受体上的作用,现在带来了许多益处。
