Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective inhibitor of dipeptidyl peptidase-4 (DPP-4), increasing levels of active incretin hormones (GLP-1, GIP), enhancing glucose-dependent insulin secretion and suppressing glucagon release.
Saxagliptin inhibits DPP-4, increasing incretin levels (GLP-1, GIP), enhancing glucose-dependent insulin secretion and reducing glucagon. Metformin decreases hepatic glucose production, reduces intestinal glucose absorption, and improves insulin sensitivity.
100 mg orally once daily
Each tablet contains saxagliptin 5 mg and metformin hydrochloride 500 mg or 1000 mg. The recommended starting dose is 5 mg saxagliptin and 500 mg metformin hydrochloride orally twice daily; titrate gradually based on efficacy and tolerability. Maximum daily dose: saxagliptin 5 mg, metformin hydrochloride 2000 mg.

Terminal elimination half-life: 12.4 hours. Clinical context: supports once-daily dosing in patients with normal renal function.
Saxagliptin: 2.5 hours (parent), 3.1 hours (active metabolite). Metformin: 6.2 hours (plasma), prolonged in renal impairment.
Renal: approximately 87% (79% unchanged sitagliptin, 16% metabolites). Fecal/biliary: 13% (metabolites and unchanged drug).
Saxagliptin: 75% renal (24% unchanged, 51% as metabolite), 22% fecal. Metformin: 90% renal (unchanged).
