Short-Acting vs Long-Acting Formulations Short-acting GLP-1 medications have shorter half-lives and more frequent dosing: Exenatide immediate-release (Byetta) Half-life of approximately 24 hours, administered twice daily Lixisenatide (Lyxumia) Half-life of approximately 3 hours, administered once daily [19] Long-acting formulations demonstrate markedly different pharmacokinetics: Semaglutide Half-life of approximately 7 days (168 hours), administered weekly Dulaglutide Half-life of approximately 5 days (120 hours), administered weekly Liraglutide Half-life of approximately 13 hours, administered daily Exenatide extended-release Half-life of approximately 2 weeks, administered weekly Clearance Pathways GLP-1 medications are eliminated from the body through different pathways depending on the specific agent: Exenatide and lixisenatide are primarily eliminated through the kidneys
