Common Name

Icatibant

Class

Small Molecule

Description

Icatibant (Firazyr) is a synthetic peptidomimetic drug consisting of ten amino acids, and acts as an effective and specific antagonist of bradykinin B2 receptors. It has been approved in the EU for use in hereditary angioedema, and is under investigation for a number of other conditions in which bradykinin is thought to play a significant role. Icatibant currently has orphan drug status in the United States and FDA approved on August 25, 2011.
