Sodium-glucose co-transporter-2 inhibitors (SGLT2i) have been proven to lead to relevant cardiovascular benefits, regardless of glycemic control function. SGLT2i have on the one hand led to reduction in cardiovascular events such as heart failure and on the other hand to renal protection. Blood pressure reduction and kidney function play a central role in these outcomes. This focused review describes the main mechanisms and clinical aspects of SGLT2i.
These drugs act on the proximal renal tubule and behave as diuretics with a "hybrid" mechanism, as they can favour both natriuresis and enhanced diuresis due to an osmotic effect dependent on glycosuria, resulting in blood pressure decrease. The exclusive peculiarity of these "diuretics", which distinguishes them from loop and thiazide diuretics, lies also in the activation of the tubule-glomerular feedback.
This mechanism, resulting in modulation of arterioles' tone and renin secretion, contributes to the favorable outcomes, suggesting a wider use of SGLT2i in internal medicine, nephrology and cardiology.
钠-葡萄糖共转运蛋白 2 抑制剂(SGLT2i)已被证明可带来相关的心血管获益,而与血糖控制功能无关。SGLT2i 一方面导致心力衰竭等心血管事件减少,另一方面导致肾脏保护。血压降低和肾功能在这些结果中起着核心作用。本重点综述描述了 SGLT2i 的主要机制和临床方面。
这些药物作用于近端肾小管,表现为具有“混合”机制的利尿剂,因为它们可以通过依赖于糖尿的渗透作用促进钠排泄和增强利尿,从而导致血压下降。这些“利尿剂”的独特之处,即它们与袢利尿剂和噻嗪类利尿剂的区别,还在于激活管-球反馈。
这种机制导致小动脉张力和肾素分泌的调节,有助于获得有利的结果,提示在内科、肾病学和心脏病学中更广泛地使用 SGLT2i。
