By activating GLP-1 receptors, these drugs enhance glucose-dependent insulin secretion, suppress glucagon release, slow gastric emptying, and influence central appetite signaling
Rather than targeting more receptors with a single molecule, it combines two separate compounds, cagrilintide (an amylin analogue) and semaglutide (a GLP-1 agonist), into a single weekly injection
It helps catch deficiencies early, preventing severe anemia and other issues
As a sympathomimetic amine, phentermine increases norepinephrine and dopamine activity
e.g., under nutrient starvation, being able to provide substrates for ATP production and macromolecule synthesis (Zhang, 2013)
