GLYXAMBI vs INVOKAMET XR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
GLYXAMBI is a combination of empagliflozin, a sodium-glucose co-transporter-2 (SGLT2) inhibitor, and linagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor. Empagliflozin reduces renal glucose reabsorption, increasing urinary glucose excretion. Linagliptin increases incretin hormones (GLP-1, GIP), enhancing insulin release and decreasing glucagon levels in a glucose-dependent manner.
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.
10 mg/5 mg orally once daily (empagliflozin/linagliptin). May increase to 25 mg/5 mg once daily if tolerated.
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.

Empagliflozin: Terminal half-life ~12.4 hours allows once-daily dosing. Linagliptin: Terminal half-life >100 hours, but pharmacodynamic effect correlates with DPP-4 inhibition rather than plasma levels.
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.
Empagliflozin: Approximately 95.6% excreted in feces (41.2% as unchanged drug) and 54.4% in urine (19.8% as unchanged). Linagliptin: 84% excreted in feces via enterohepatic circulation (80% as parent drug) and 5% in urine.
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.
