Generic Icatibant Injection works in the same way that Firazyr®* does. It is a selective bradykinin type 2–receptor (B2R) antagonist.
What does that mean?
People with Hereditary angioedema (HAE) can enter into an uncontrolled production of a protein called bradykinin. Bradykinin binds to the receptor, B2R, found on the lining of blood vessels. When bradykinin is bound to the B2R, the blood vessels vasodilate and allow fluid to pass through leading to swelling.
The most common side effects of Icatibant Injection include:
