𧬠Pharmacological Profile
Semaglutide is a highly stable, synthetic analogue of human glucagon-like peptide-1 (GLP-1). It has been structurally modified to resist degradation by the DPP-4 enzyme, dramatically extending its half-life to approximately 7 days and allowing for once-weekly administration.
It operates via a dual-action mechanism. Systemically, it dramatically slows gastric motility (the rate at which the stomach empties), resulting in prolonged physical satiety. Neurologically, it crosses the blood-brain barrier to bind with GLP-1 receptors in the hypothalamus, aggressively modulating hunger signals and reducing the compulsion for caloric intake.
