产品详细信息

详细说明 (English)

• Drug Groups: approved; investigational
• Description: Icatibant (Firazyr) is a peptidomimetic drug consisting of ten amino acids, which is 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.
• Indication: Approved for use in hereditary angioedema. Investigated for use/treatment in angioedema, liver disease, and burns and burn infections.
• Pharmacology: Icatibant is a potent, specific and selective peptidomimetic bradykinin beta2-receptor antagonist (pA2 = 9.04). It has a modified peptide structure, and is the first bradykinin receptor antagonist to act on the guinea-pig trachea without demonstrating agonist effects. It also inhibits aminopeptidase N (Ki = 9.1 μM).
• Affected Organisms: Humans and other mammals
• Half Life: Elimination half-lives calculated from linear regression of the mean data were 25, 27 and 29 min after 20, 50 and 100 micrograms kg-1 doses respectively.
