Mechanism of action

Aprotinin inhibits kallikrein, plasmin, and other proteases involved in the coagulation cascade and fibrinolysis. When inhaled, it is intended to reduce excessive protease activity in the lungs, potentially decreasing inflammation, bleeding, and tissue damage in respiratory conditions. This mechanism may help preserve lung function and reduce complications in conditions characterized by excessive proteolytic activity.
