Icatibant (Firazyr)

Bradykinin B2 receptor antagonist for hereditary angioedema attacks.

Mechanism

Synthetic decapeptide that competitively blocks the bradykinin B2 receptor, halting the vascular leak that drives HAE swelling attacks.

Research areas
  • Hereditary angioedema (acute attacks)
Considerations
  • FDA-approved.
  • Injection-site reactions very common.

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.
