What are Amylin Analogs?

Definition & Mechanism of Action:
Amylin analogs are synthetic derivatives of human amylin, a pancreatic hormone co-secreted with insulin. They function primarily by delaying gastric emptying, suppressing glucagon secretion, and promoting satiety, thereby reducing postprandial hyperglycemia and aiding weight loss.

Key Drugs in the Class:	Brand Name	Generic Name	Approval Year	Indications	Formulation
Symlin	Pramlintide	2005	T1DM and T2DM (adjunct to insulin)	Subcutaneous injection
AM833 (V Vass)	Setmelanotide*	2016	Rare genetic obesity syndromes	Subcutaneous injection
Ertislintide	Ectrisintide	Under Development	Obesity, T2DM	Injectable/inhaled (experimental)

*Note: Setmelanotide modulates melanocortin-4 receptor pathways but exhibits overlaps and differs from canonical amylin analogs.
