Ertugliflozin (it is claimed) has a 2000-fold increase in selectivity for human SGLT2 over SGLT1 (IC50: SGLT2 = 0.877 nM vs SGLT1 = 1960 nM) in vitro.
In vivo
Ertugliflozin is rapidly absorbed in preclinical species after oral administration, and it is characterized by low clearance (excreted in the urine in preclinical species) and a moderate steady-state distribution volume. There is low potential for pharmacokinetic interaction of ertugliflozin. Ertugliflozin is well absorbed in humans and eliminated largely via glucuronidation. Ertugliflozin improved glycemic control, body weight and blood pressure in patients with T2DM suboptimally controlled by metformin, and is well-tolerated.
