SNAP-8GLP-1 / Weight Loss Agonists
Dulaglutide- Summary
- SNAP-8 is a synthetic octapeptide cosmetic ingredient that reduces the depth of expression lines and wrinkles by competitively inhibiting the SNARE complex involved in acetylcholine release at neuromuscular junctions, providing a topical 'Botox-like' effect.
- Dulaglutide (brand name Trulicity) is a once-weekly GLP-1 receptor agonist approved by the FDA for type 2 diabetes management and cardiovascular risk reduction. It consists of two GLP-1 analog chains fused to a modified IgG4 Fc fragment, extending its half-life to approximately 5 days. While primarily a diabetes medication, it produces meaningful weight loss and has established cardiovascular outcomes data from the REWIND trial.
