BYDUREON PEN vs XULTOPHY 100/3.6
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucagon-like peptide-1 (GLP-1) receptor agonist; increases insulin secretion, suppresses glucagon release, slows gastric emptying, and promotes satiety.
Xultophy 100/3.6 is a combination of insulin degludec (a long-acting basal insulin analog) and liraglutide (a GLP-1 receptor agonist). Insulin degludec binds to insulin receptors, promoting cellular glucose uptake and inhibiting hepatic glucose production. Liraglutide activates GLP-1 receptors, increasing insulin secretion, decreasing glucagon secretion, and slowing gastric emptying.
2 mg subcutaneously once every 7 days (weekly)
Subcutaneous injection once daily, starting at 10 units (10 units insulin degludec and 3.6 mcg liraglutide). Titrate by 2 units every 3-4 days based on fasting plasma glucose to a maximum of 50 units daily.

Terminal elimination half-life is 2.4 hours following subcutaneous administration; due to extended-release microspheres, systemic exposure is sustained over 10 weeks with multiple dosing (effective half-life ~2 weeks).
Insulin degludec: ~25 hours (range 22-28 hours); liraglutide: ~13 hours. The ultra-long half-life of insulin degludec allows once-daily dosing with flat activity profile.
Renal excretion of intact exenatide via glomerular filtration and proteolytic degradation; approximately 100% of administered dose eliminated via renal pathways (urine) as intact peptide and metabolites.
Renal: insulin degludec and liraglutide are cleared primarily via degradation, with less than 2% excreted unchanged renally. Fecal: negligible.
