💊 Profile
Complement C1 esterase inhibitor is an endogenous complement blocker that plays a role in regulation of the complement system. It is prepared from human plasma and given as replacement therapy in hereditary angioedema, in which there is a deficiency of natural complement C1-esterase inhibitor. It is given for both short-term prophylaxis and treatment of acute life-threatening attacks by slow intravenous injection or infusion in typical doses of 500 units or, in severe cases, 1000 units. The dose may be repeated if necessary after a few hours. A recombinant human complement C1 esterase inhibitor (rh C1INH) is under investigation.
◊ Complement C1 esterase inhibitor may be effective in both the prevention and treatment of acute hereditary angioedema.1
It has also been tried in the management of other conditions including sepsis and capillary leak syndrome.2 It is under investigation for the treatment of pancreatitis and for use in allogeneic lung transplantation, thermal injury, and shock.2 It is also being studied as a means of limiting reperfusion injury in patients with acute myocardial infarction.31.
