CAS 130308-48-4: Icatibant
Description:Icatibant is a synthetic peptide and a selective bradykinin B2 receptor antagonist, primarily used in the treatment of hereditary angioedema, a condition characterized by recurrent episodes of severe swelling. Its mechanism of action involves blocking the effects of bradykinin, a peptide that promotes vasodilation and increases vascular permeability, thereby alleviating the symptoms associated with angioedema. Icatibant is administered via subcutaneous injection and is known for its rapid onset of action. The substance has a relatively short half-life, necessitating careful dosing to maintain therapeutic levels. In terms of chemical structure, Icatibant is a nonapeptide, which contributes to its specificity and efficacy in targeting the bradykinin receptor. Its safety profile is generally favorable, with common side effects including injection site reactions and gastrointestinal disturbances. Overall, Icatibant represents a significant advancement in the management of hereditary angioedema, providing patients with a targeted therapeutic option to control acute attacks.
