Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibitor of dipeptidyl peptidase-4 (DPP-4), preventing inactivation of incretin hormones (GLP-1, GIP), thereby increasing insulin secretion and decreasing glucagon release in a glucose-dependent manner.
Sitagliptin is a DPP-4 inhibitor that increases incretin levels (GLP-1, GIP), enhancing glucose-dependent insulin secretion and reducing glucagon secretion. Metformin is a biguanide that decreases hepatic glucose production, decreases intestinal glucose absorption, and improves insulin sensitivity via AMP-kinase activation.
25 mg orally once daily.
1 tablet orally twice daily; each tablet contains sitagliptin 50 mg and metformin hydrochloride 500 mg, 850 mg, or 1000 mg; maximum dose: sitagliptin 100 mg/day, metformin 2000 mg/day.

Terminal elimination half-life: 12.4–26.1 hours (mean ~21 hours); supports once-daily dosing
Sitagliptin: terminal half-life 12.4 hours (healthy), prolonged in renal impairment (up to 28–39 hours in severe impairment). Metformin: terminal half-life 4–8.7 hours (healthy), prolonged in renal impairment (up to 17.6 hours in moderate impairment).
Renal: 87% (75% as unchanged drug, 12% as inactive metabolites); Fecal: <1%
Sitagliptin: 79% excreted unchanged in urine via renal tubular secretion and glomerular filtration; 13% metabolized with 4% excreted in feces. Metformin: 90% excreted unchanged in urine via glomerular filtration and tubular secretion; <5% in feces.
