About

About Pramlintide

Pramlintide is a synthetic analog of amylin FDA-approved as an adjunct to mealtime insulin in type 1 and type 2 diabetes (brand: Symlin, NDA 021332). Amylin is co-secreted with insulin by pancreatic beta cells and is deficient in insulin-dependent diabetes. Pramlintide slows gastric emptying, suppresses postprandial glucagon, and reduces appetite. It is used off-label in obesity and GLP-1 combination protocols by metabolic physicians.

Science

Mechanism of Action

Amylin receptor agonist (AMY1–3, RAMP1–3 heterodimers). Activates area postrema and nucleus tractus solitarius circuits to suppress glucagon secretion after meals, delay gastric emptying, and signal satiety. Unlike GLP-1 agonists, pramlintide does not stimulate insulin release. Proline substitutions at positions 25, 28, 29 prevent amyloid fibril formation seen with native amylin.

Dosing

Typical Protocol

Type 1 DM: 15 mcg SC immediately before major meals, titrate to 30–60 mcg. Type 2 DM: 60 mcg SC before major meals, titrate to 120 mcg if tolerated. Must reduce mealtime insulin dose by 50% at initiation to avoid hypoglycemia. Administer in a separate syringe from insulin (incompatible in mixture). Requires physician supervision and glucose monitoring.
