Clinical Matrix

Mechanism of Action

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 inhibits dipeptidyl peptidase-4 (DPP-4), increasing endogenous incretin hormones (GLP-1, GIP) which enhance insulin secretion and decrease glucagon levels in a glucose-dependent manner. Metformin activates AMP-activated protein kinase (AMPK), decreasing hepatic glucose production and improving insulin sensitivity.

Clinical Dosing

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.

Initial dose based on current metformin dose: for patients not on metformin, start with sitagliptin 50 mg/metformin 500 mg PO BID; for metformin monotherapy, switch to sitagliptin 50 mg/metformin 500 mg or 1000 mg PO BID; for patients on sitagliptin, start with sitagliptin 50 mg/metformin 500 mg or 1000 mg PO BID. Maximum daily dose: sitagliptin 100 mg, metformin 2000 mg.
