Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Alogliptin is a selective, reversible inhibitor of dipeptidyl peptidase-4 (DPP-4). By inhibiting DPP-4, it increases the levels of active incretin hormones (GLP-1 and GIP), which stimulate insulin secretion in a glucose-dependent manner and suppress glucagon release, thereby improving glycemic control.
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.
25 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 is approximately 12-21 hours. This supports once-daily dosing. In patients with renal impairment, half-life is prolonged (e.g., up to 32 hours in severe impairment), necessitating dose adjustment.
Saxagliptin: 2.5 hours (parent), 3.1 hours (active metabolite). Metformin: 6.2 hours (plasma), prolonged in renal impairment.
Approximately 60-71% of the dose is excreted unchanged in urine via active renal tubular secretion, with about 20% eliminated as metabolites (primarily N-demethylated and N-acetylated derivatives) in urine, and less than 2% in feces. Renal excretion is the major route.
Saxagliptin: 75% renal (24% unchanged, 51% as metabolite), 22% fecal. Metformin: 90% renal (unchanged).
