INVOKAMET vs STEGLUJAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
INVOKAMET is a combination of canagliflozin, an SGLT2 inhibitor, and metformin, a biguanide. Canagliflozin inhibits sodium-glucose cotransporter 2 in the renal proximal tubules, reducing glucose reabsorption and increasing urinary glucose excretion. Metformin decreases hepatic glucose production, decreases intestinal absorption of glucose, 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.
Oral: Starting dose: 5 mg canagliflozin/500 mg metformin hydrochloride extended-release twice daily; titrate based on efficacy and tolerability, maximum 150 mg/1000 mg twice daily.
Initial: 5 mg/100 mg orally once daily; increase dose based on glycemic response up to 15 mg/100 mg.

Canagliflozin: 10–13 hours (multiple dosing); Metformin: 6.2 hours (plasma). Accumulation occurs 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 (SGLT2 inhibitor): ~33% renal (1% unchanged, ~33% as glucuronide metabolites), ~52% fecal. Metformin (biguanide): 90% renal unchanged via tubular secretion.
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).
