JENTADUETO vs SITAGLIPTIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Jentadueto is a combination of linagliptin and metformin. Linagliptin inhibits DPP-4, increasing incretin levels (GLP-1, GIP) and enhancing glucose-dependent insulin secretion while suppressing glucagon. Metformin decreases hepatic glucose production, reduces intestinal glucose absorption, and improves insulin sensitivity.
Sitagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor that increases active incretin (GLP-1 and GIP) levels by preventing their degradation, thereby enhancing insulin secretion and suppressing glucagon release in a glucose-dependent manner.
Administered orally twice daily with meals. Initial dose: one tablet JENTADUETO 5 mg/500 mg or 5 mg/1000 mg; subsequent titration based on glycemic response. Maximum daily dose: linagliptin 5 mg, metformin 2000 mg.
100 mg orally once daily.

Clinical Note
moderateSitagliptin + Trovafloxacin
"Sitagliptin may increase the hypoglycemic activities of Trovafloxacin."
Linagliptin: terminal t1/2 ~12 hours (long binding to DPP-4). Metformin: terminal t1/2 ~6.2 hours (renal impairment prolongs).
12.4 hours; supports once-daily dosing with effect ≥24 h due to sustained DPP-4 inhibition.
Renal: linagliptin ~5% unchanged; metformin ~90% unchanged. Fecal: linagliptin ~80% (mostly unchanged). Biliary: minimal.
Renal: ~87% unchanged in urine (active tubular secretion); fecal: <13% (metabolites).
