ANP (Atrial Natriuretic Peptide) vs Pramlintide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
ANP (Atrial Natriuretic Peptide)
ANP is a cardiac hormone released by atrial myocytes in response to stretch. It promotes natriuresis, diuresis, and vasodilation, playing key roles in blood pressure and fluid regulation.
Full details →Pramlintide
Pramlintide (Symlin) is a synthetic analog of amylin, FDA-approved as an adjunct to insulin therapy in type 1 and type 2 diabetes. It helps control post-meal blood sugar spikes and promotes modest weight loss.

| Aspect | ANP (Atrial Natriuretic Peptide) | Pramlintide |
|---|---|---|
| Mechanism | Binds to natriuretic peptide receptors (NPR-A) to activate guanylyl cyclase, producing cGMP. This leads to vasodilation, increased kidney filtration, and inhibition of the renin-angiotensin-aldosterone system. | Mimics amylin's effects: slows gastric emptying, suppresses glucagon secretion after meals, and promotes satiety through central mechanisms. Complements insulin therapy. |
| Typical Dosage | Clinical use: Carperitide (recombinant ANP) used in Japan for acute heart failure at 0.1mcg/kg/min IV infusion. | Type 1: Start 15mcg before meals, titrate to 30-60mcg. Type 2: Start 60mcg, may increase to 120mcg. Always with meal containing 30+ grams carbs or 250+ calories. |
| Administration | Intravenous infusion only for clinical applications. Short half-life (~2 minutes) requires continuous administration. | Subcutaneous injection immediately before major meals. Must reduce mealtime insulin by 50% when starting to prevent hypoglycemia. Never mix with insulin. |
| Side Effects | Hypotension (dose-limiting), headache, nausea, and potential arrhythmias at high doses. | Nausea (very common initially), headache, anorexia, vomiting, and abdominal pain. GI effects typically improve over time. |
