INVOKAMET XR vs STEGLUJAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination of canagliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, which reduces renal glucose reabsorption and lowers blood glucose, and metformin, an activator of AMP-activated protein kinase (AMPK) that decreases hepatic glucose production and improves insulin sensitivity.
STEGLUJAN is a combination of ertugliflozin and sitagliptin. Ertugliflozin is a sodium-glucose cotransporter 2 (SGLT2) inhibitor that reduces renal glucose reabsorption, increasing urinary glucose excretion. Sitagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor that increases incretin levels (GLP-1 and GIP), enhancing insulin secretion and reducing glucagon secretion.
Maximum daily dose: canagliflozin 300 mg/metformin ER 2000 mg orally once daily with the morning meal. Initial dose: canagliflozin 50 mg/metformin ER 500 mg orally twice daily or canagliflozin 150 mg/metformin ER 1000 mg orally once daily; for patients not currently on metformin, start with canagliflozin 50 mg/metformin ER 500 mg orally twice daily; for patients on metformin, switch to INVOKAMET XR based on current metformin dose.
Initial: 5 mg/100 mg orally once daily; increase dose based on glycemic response up to 15 mg/100 mg.

Canagliflozin: mean terminal elimination half-life is 13.1 hours (range 11-16 hours) for the 300 mg dose, consistent with once-daily dosing. Metformin: terminal elimination half-life is approximately 6.2 hours (range 4-9 hours) in patients with normal renal function; prolonged in renal impairment.
Terminal elimination half-life is 12–15 hours (mean 13.5 h) in patients with normal renal function; approximately 1.5- to 2-fold longer in moderate renal impairment (eGFR 30–59 mL/min) and up to 3-fold longer in severe renal impairment (eGFR <30 mL/min), necessitating dose reduction.
Canagliflozin is primarily excreted as unchanged drug in urine (approximately 33%) and feces (approximately 41%), with about 7% as metabolites in urine and 34% as metabolites in feces. Metformin is excreted unchanged in urine (90-100% of absorbed dose) via tubular secretion and glomerular filtration.
Approximately 70% of an absorbed dose is excreted in the urine (30% as unchanged steglujan, 40% as its active glucuronide metabolite), and 30% is excreted in the feces (primarily as metabolites and unchanged drug via biliary secretion).
