Ecallantide (Kalbitor) vs Plecanatide (Trulance)

An educational, source-based comparison of Ecallantide (Kalbitor) and Plecanatide (Trulance) — how each peptide works, what it's researched for, and what to know before going deeper.

Kallikrein Inhibitor · Immunology
Ecallantide (Kalbitor)

Plasma kallikrein inhibitor for hereditary angioedema.

Mechanism

60-amino-acid recombinant protein that selectively inhibits plasma kallikrein, reducing bradykinin generation during HAE attacks.

Research areas
  • Hereditary angioedema (acute attacks, ≥12 yrs)
Considerations
  • FDA-approved.
  • Boxed warning: anaphylaxis — administer by healthcare professional.

GC-C Agonist · Gastrointestinal
Plecanatide (Trulance)

Uroguanylin analog for chronic constipation.

Mechanism

Synthetic analog of human uroguanylin that activates guanylate cyclase-C in a pH-dependent manner, increasing intestinal fluid secretion and transit.

Research areas
  • Chronic idiopathic constipation
  • IBS-C
Considerations
  • FDA-approved.
  • Diarrhea most common adverse event.
