Amylin is a 37 amino acid peptide hormone co-secreted with insulin mostly by the pancreatic β cells in response to meals. Amylin has several known effects including suppression of postprandial glucagon secretion, regulation of gastric emptying, and reduction of food intake. Pramlintide is an amylin analog recently approved by the Food and Drug Administration (FDA) to be given at meal time as an adjunct to insulin therapy in patients with type 1 or type 2 diabetes who have failed to achieve desired glucose control despite optimal insulin therapy or insulin therapy with or without a sulfonylurea agent and/or metformin. Several clinical trials showed that meal time amylin replacement with pramlintide along with insulin therapy improved post-prandial hyperglucagonemia, and reduced post-prandial glucose excursion. A recent randomized control trial showed that pramlintaide reduced weight by up to 2kg in both type 1 and type 2 diabetes.
