JANUVIA vs ZITUVIO
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.
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.

Terminal elimination half-life: 12.4 hours. Clinical context: supports once-daily dosing in patients with normal renal function.
Terminal elimination half-life 6-8 hours in healthy adults; extended to 20-30 hours in severe renal impairment (CrCl <30 mL/min).
Renal: approximately 87% (79% unchanged sitagliptin, 16% metabolites). Fecal/biliary: 13% (metabolites and unchanged drug).
Primarily renal (75-80% as unchanged drug), with 15-20% as inactive metabolites; biliary/fecal <5%.
