Pharmacology
Sevelamer carbonate is a non-absorbed phosphate-binding cross-linked polymer, free of metal and calcium, that binds phosphate in the gastrointestinal tract via ionic and hydrogen bonding, thereby decreasing phosphate absorption and lowering serum phosphorus concentrations.
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.
