Key differences

What each one treats

VictozaLiraglutide

VICTOZA is indicated: • as an adjunct to diet and exercise to improve glycemic control in patients 10 years and older with type 2 diabetes mellitus, • to reduce the risk of major adverse cardiovascular events (cardiovascular death, non-fatal myocardial infarction, or non-fatal stroke) in adults with type 2 diabetes mellitus and established cardiovascular disease [see Clinical Studies ( 14.3 )] . Limitations of Use : VICTOZA should not be used in patients with type 1 diabetes mellitus. VICTOZA contains liraglutide and should not be coadministered with other liraglutide-containing products. VICTOZA is a glucagon-like peptide-1 (GLP-1) receptor agonist indicated: • as an adjunct to diet and exercise to improve glycemic control in patients 10 years and older with type 2 diabetes mellitus (1) . • to reduce the risk of major adverse cardiovascular events in adults with type 2 diabetes mellitu…

ByettaExenatide

BYETTA is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. Limitations of Use • BYETTA contains exenatide. Coadministration with other exenatide-containing products is not recommended. BYETTA (exenatide) is a glucagon-like peptide-1 (GLP-1) receptor agonist indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. ( 1 , 14 ) Limitations of Use • Coadministration with other exenatide-containing products is not recommended ( 1 ).

How each one works

VictozaGLP-1 receptor agonist

12.1 Mechanism of Action Liraglutide is an acylated human Glucagon-Like Peptide-1 (GLP-1) receptor agonist with 97% amino acid sequence homology to endogenous human GLP-1(7-37). GLP-1(7-37) represents <20% of total circulating endogenous GLP-1. Like GLP-1(7-37), liraglutide activates the GLP-1 receptor, a membrane-bound cell-surface receptor coupled to adenylyl cyclase by the stimulatory G-protein, Gs, in pancreatic beta cells. Liraglutide increases intracellular cyclic AMP (cAMP) leading to insulin release in the presence of elevated glucose concentrations. This insulin secretion subsides as blood glucose concentrations decrease and approach euglycemia. Liraglutide also decreases glucagon …

ByettaGLP-1 receptor agonist

12.1 Mechanism of Action Incretins, such as glucagon-like peptide-1 (GLP-1), enhance glucose-dependent insulin secretion and exhibit other antihyperglycemic actions following their release into the circulation from the gut. BYETTA is a GLP-1 receptor agonist that enhances glucose-dependent insulin secretion by the pancreatic beta-cell, suppresses inappropriately elevated glucagon secretion, and slows gastric emptying. The amino acid sequence of exenatide partially overlaps that of human GLP-1. Exenatide has been shown to bind and activate the human GLP-1 receptor in vitro . This leads to an increase in both glucose-dependent synthesis of insulin, and in vivo secretion of insulin from pancre…

This is not medical advice, and not a recommendation of one drug over the other.

Which medicine is right for a given person depends on their diagnosis, other conditions, other medicines, kidney and liver function, pregnancy, and cost or reimbursement — none of which this page knows. Two drugs in the same class are not automatically interchangeable. Never start, stop or switch a prescription medicine on the basis of a web page; that decision belongs to you and your clinician or pharmacist.

Class and summary text is written by the Priya Life Science editorial team. Label, mechanism, route, manufacturer and approval data come from the U.S. FDA via the openFDA API; shortage status from the FDA Drug Shortage Database. Approvals, indications and brand names differ between the US, EU/Ireland (EMA/HPRA) and other regions — a drug approved in one may not be approved, or may carry a different name, in another.
