Biology & mechanism

Human amylin aggregates into amyloid fibrils, which makes it undruggable. Pramlintide substitutes three prolines — borrowed from rat amylin, which does not aggregate — producing a soluble analog with retained activity. It slows gastric emptying, suppresses inappropriate postprandial glucagon, and promotes satiety via the area postrema. It is the approved proof-of-concept for the mechanism cagrilintide is now pursuing.

What the research actually shows

Approved in 2005 on trials in type 1 and type 2 diabetes as mealtime adjunct therapy to insulin. Commercially marginal, but the pharmacology is established.

Regulatory status

FDA-approved as adjunct mealtime therapy with insulin in type 1 and type 2 diabetes. Prescription-only.

Safety signals

Boxed warning for severe insulin-induced hypoglycaemia, typically within three hours of dosing. Requires concurrent insulin dose reduction and close glucose monitoring — this is genuinely a drug that kills people who use it casually. Nausea is common.
