Why is liraglutide dosed daily rather than weekly?

Name: Liraglutide
Price: 98 USD
Availability: InStock

Liraglutide has a 13-hour half-life, substantially shorter than semaglutide (7 days) or tirzepatide (5 days). Daily dosing is required to maintain therapeutic concentrations. Newer once-weekly GLP-1 agonists achieved extended half-lives through more stable albumin-binding modifications.

Mechanism of Action

Liraglutide is a GLP-1 analog with 97% amino acid sequence homology to native GLP-1, modified at position 34 (arginine replaces lysine) and with a C16 fatty acid attached to lysine at position 26. These changes allow self-association and albumin binding that extends the half-life to 13 hours. It activates GLP-1 receptors to suppress glucagon, stimulate glucose-dependent insulin secretion, slow gastric emptying, and reduce appetite via central hypothalamic pathways.
