Ecallantide (Kalbitor) vs Linaclotide (Linzess)
An educational, source-based comparison of Ecallantide (Kalbitor) and Linaclotide (Linzess) — how each peptide works, what it's researched for, and what to know before going deeper.
Plasma kallikrein inhibitor for hereditary angioedema.
60-amino-acid recombinant protein that selectively inhibits plasma kallikrein, reducing bradykinin generation during HAE attacks.
- Hereditary angioedema (acute attacks, ≥12 yrs)
- • FDA-approved.
- • Boxed warning: anaphylaxis — administer by healthcare professional.
Guanylate cyclase-C agonist peptide for IBS-C and chronic constipation.
14-amino-acid peptide that activates intestinal guanylate cyclase-C, increasing cGMP and chloride/bicarbonate secretion into the gut lumen — accelerating transit and reducing visceral pain.
- IBS-C
- Chronic idiopathic constipation
- Functional constipation in children
- • FDA-approved.
- • Contraindicated in children <2 years; diarrhea common.
