Pharmacology
SGLT2 inhibitor; dapagliflozin inhibits sodium-glucose cotransporter 2 in the proximal renal tubules, reducing glucose reabsorption and promoting urinary glucose excretion, while also reducing sodium reabsorption to lower cardiac pre- and afterload, suppress sympathetic activity, and decrease intraglomerular pressure via tubuloglomerular feedback.
Empagliflozin is an SGLT2 inhibitor that reduces renal reabsorption of filtered glucose, lowers the renal threshold for glucose, and increases urinary glucose excretion; metformin HCl is a biguanide antihyperglycemic agent that decreases hepatic glucose production, reduces intestinal absorption of glucose, and improves insulin sensitivity by increasing peripheral glucose uptake and utilization.
