Mechanism of ActionSemaglutide mimics the GLP-1 hormone, slowing gastric emptying, increasing insulin secretion, reducing glucagon release, and acting on brain appetite centers to reduce hunger and increase satiety. It has 94% amino acid similarity to human GLP-1.Dulaglutide consists of two GLP-1 analogs linked to a modified human IgG4 Fc fragment. This structure extends half-life to about 5 days, allowing weekly dosing. Works through standard GLP-1 receptor activation.

Research SummarySTEP trials demonstrated average weight loss of 15-17% body weight over 68 weeks. SELECT trial showed 20% reduction in major cardiovascular events. Proven efficacy for glycemic control in type 2 diabetes with A1C reductions of 1.5-2%.AWARD program showed significant A1C reduction and weight loss. REWIND trial demonstrated cardiovascular benefits in broader diabetic population. Generally shows 3-5% weight loss in trials.

Frequently Asked Questions: Semaglutide vs Dulaglutide

What is the difference between Semaglutide and Dulaglutide?

Semaglutide is a weight loss peptide that a glp-1 receptor agonist fda-approved for type 2 diabetes and chronic weight management. one of the most effective pharmaceutical weight loss interventions available. Dulaglutide is a weight loss peptide that an fda-approved weekly glp-1 receptor agonist for type 2 diabetes. fused to an fc antibody fragment for extended duration of action. The main differences lie in their mechanisms of action and clinical applications.

Which is better, Semaglutide or Dulaglutide?

Neither is universally "better" - the choice depends on your specific goals. Semaglutide is typically used for weight loss purposes, while Dulaglutide is used for weight loss. Always consult with a healthcare provider to determine which may be appropriate for your situation.

Can Semaglutide and Dulaglutide be used together?

Some peptide protocols combine multiple compounds for synergistic effects. However, using Semaglutide and Dulaglutide together should only be considered under medical supervision, as both compounds have their own side effect profiles and potential interactions. Research on their combined use may be limited.
