empagliflozin brands

Molecular formula: C23H27ClO7

The vast majority of glucose filtered through the glomerulus is reabsorbed within the proximal tubule, primarily via SGLT2 (sodium-glucose linked co-transporter-2) which is responsible for ~90% of the total glucose reabsorption within the kidneys. Na⁺/K⁺-ATPase on the basolateral membrane of proximal tubular cells utilize ATP to actively pump Na+ ions into the interstitium surrounding the tubule, establishing a Na⁺ gradient within the tubular cell. SGLT2 on the apical membrane of these cells then utilize this gradient to facilitate secondary active co-transport of both Na+ and glucose out of the filtrate, thereby reabsorbing glucose back into the blood – inhibiting this co-transport, then, allows for a marked increase in glucosuria and decrease in blood glucose levels. Empagliflozin is a potent inhibitor of renal SGLT2 transporters located in the proximal tubules of the kidneys and works to lower blood glucose levels via an increase in glucosuria. Empagliflozin also appears to exert cardiovascular benefits - specifically in the prevention of heart failure - independent of its blood glucose-lowering effects, though the exact mechanism of this benefit is not precisely understood. Several theories have been posited, including the potential inhibition of Na⁺/H⁺ exchanger (NHE) 1 in the myocardium and NHE3 in the proximal tubule, reduction of pre-load via diuretic/natriuretic effects and reduction of blood pressure, prevention of cardiac fibrosis via suppression of pro-fibrotic markers, and reduction of pro-inflammatory adipokines.
