Beyond their established hypoglycemic, cardioprotective, and nephroprotective properties, sodium-glucose cotransporters 2 (SGLT2) inhibitors exert other pleiotropic actions on blood pressure levels, body weight, and lipid metabolism. Blood pressure (BP) reduction varies based on the background history, including an effect on systolic, diastolic BP, and 24 h BP measurements. The reduction in body weight between 1 and 2 kg for the first months is caused by a reduction in visceral and subcutaneous fat due to glycosuria and loss of calories. Regarding lipid metabolism, a reduction in triglycerides and an increase in total cholesterol, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) have been reported, although these alterations are small and could provide additional cardiovascular protection. Various pathophysiologic mechanisms have been proposed to explain the above-mentioned pleiotropic actions of SGLT2 inhibitors. Natriuresis, osmotic diuresis, body weight reduction, amelioration of endothelial dysfunction and arterial stiffness, sympathetic tone decrease, and uric acid reduction are among those that have been suggested for BP reduction. Apart from glycosuria and calorie loss, other mechanisms seem to contribute to body weight reduction, such as the beiging of white adipose tissue, while the mechanisms involved in lipid metabolism alterations have not been clearly determined.
除了已确定的降血糖、心脏保护和肾脏保护作用外,钠-葡萄糖共转运蛋白 2(SGLT2)抑制剂对血压水平、体重和脂质代谢还具有其他多效作用。血压(BP)的降低取决于背景病史,包括对收缩压、舒张压和 24 小时 BP 测量的影响。由于尿糖和卡路里丢失,在前几个月体重减轻 1 至 2 公斤,这是由于内脏和皮下脂肪减少所致。关于脂质代谢,据报道甘油三酯降低,总胆固醇、高密度脂蛋白(HDL)和低密度脂蛋白(LDL)增加,尽管这些变化很小,但可以提供额外的心血管保护。已经提出了各种病理生理机制来解释 SGLT2 抑制剂的上述多效作用。利钠、渗透利尿、体重减轻、改善内皮功能和动脉僵硬、交感神经张力降低以及尿酸减少等都被认为可以降低血压。除了尿糖和卡路里丢失外,其他机制似乎也有助于体重减轻,例如白色脂肪组织的褐变,而脂质代谢变化的机制尚未明确确定。
