SAXAGLIPTIN;METFORMIN HYDROCHLORIDE vs ZITUVIO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
ZITUVIO is a sodium-glucose cotransporter-2 (SGLT2) inhibitor that blocks glucose reabsorption in the proximal renal tubules, lowering blood glucose by increasing urinary glucose excretion.
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.
95 mg subcutaneously once weekly.

Saxagliptin: 2.5 hours (parent), 3.1 hours (active metabolite). Metformin: 6.2 hours (plasma), prolonged in renal impairment.
Terminal elimination half-life 6-8 hours in healthy adults; extended to 20-30 hours in severe renal impairment (CrCl <30 mL/min).
Saxagliptin: 75% renal (24% unchanged, 51% as metabolite), 22% fecal. Metformin: 90% renal (unchanged).
Primarily renal (75-80% as unchanged drug), with 15-20% as inactive metabolites; biliary/fecal <5%.
