Cinryze (complement C1 esterase inhibitor) is a man-made form of a protein that occurs naturally in the blood stream and helps control swelling in the body. People with a condition called hereditary angioedema do not have enough of this protein. Hereditary angioedema can cause attacks of swelling and symptoms such as stomach problems or trouble breathing.
Cinryze is used to prevent attacks of angioedema.
The Berinert brand of complement C1 esterase inhibitor is used to treat attacks of angioedema.
