When administered therapeutically, GLP-1 receptor agonists work through several mechanisms: Enhancing insulin secretion from pancreatic beta cells in a glucose-dependent manner [1] [4] Suppressing glucagon release from alpha cells, reducing hepatic glucose output Slowing gastric emptying , which helps moderate post-meal blood glucose rises Promoting satiety through central nervous system pathways, potentially supporting weight reduction Investigational transdermal GLP-1 delivery systems typically utilise specialised technologies such as microneedles or active delivery methods rather than conventional patches, as GLP-1 molecules are large peptides that do not easily penetrate the skin barrier
It is a complex problem that requires a multifaceted approach
A novel pathway for regulation of glucose-dependent insulinotropic polypeptide (GIP) receptor expression in beta cells
Notably, although semaglutide resulted in a slightly less pronounced weight loss, it elicited a significantly greater aversive response compared with GLP-1MK-801 (Fig
In the United States, oral and injectable forms of SMG are approved for treating T2DM, while only injectable forms are approved for treating obesity (103)
The authors write that they suspect the two medications had synergistic effects in the patient, leading to adequate control of his blood sugars yet a state of starvation, ketone production, and resultant systemic acidification
