In trials of the branded products, tirzepatide produced larger average weight reductions, while semaglutide has the longest track record and, in its branded form, a proven cardiovascular risk-reduction indication
The main protraction mechanism of semaglutide is albumin binding, facilitated by modification of position 26 lysine with a hydrophilic spacer and a C18 fatty di-acid [1-3]
The primary mechanisms of action include: Enhancing insulin secretion from pancreatic beta cells in a glucose-dependent manner, which helps lower blood glucose levels without causing hypoglycaemia when used alone Suppressing glucagon release from pancreatic alpha cells, reducing hepatic glucose production Slowing gastric emptying , which prolongs the feeling of fullness after meals Acting on appetite centres in the brain , particularly the hypothalamus, to reduce hunger and food intake GLP-1 receptor agonists are typically administered via subcutaneous injection, with dosing frequencies ranging from once daily to once weekly depending on the specific medication, though oral semaglutide (Rybelsus) is also available
