The primary mechanisms of action include: Enhancing glucose-dependent insulin secretion from pancreatic beta cells, which helps lower blood glucose levels when they are elevated Suppressing glucagon release from pancreatic alpha cells, reducing hepatic glucose production [1] [2] Slowing gastric emptying , which moderates the rate at which nutrients enter the bloodstream Promoting satiety through central nervous system pathways, leading to reduced caloric intake [1] [2] These medications are peptide-based (and one fusion protein) and are temperature sensitive
[16] Although cyanocobalamin lacks a defined upper-toxicity threshold due to its water solubility and renal elimination, exceptionally high cumulative doses have been temporally associated with acneiform eruptions, altered potassium homeostasis, and theoretical thrombotic risk, emphasizing the importance of evidence-based dosing
Demyelination, whether autoimmune or not, likely plays a role in the outcome of facial nerve pathology
