Mechanism and action
Saxenda: Saxenda acts on the GLP-1 receptor in the central nervous system and gastrointestinal tract to reduce appetite, slow gastric emptying and increase satiety. Glucophage: Metformin reduces hepatic glucose production through inhibition of mitochondrial complex I, which raises the cellular AMP/ATP ratio and activates AMP-activated protein kinase.
