About Recothrom®
Recothrom is a surgical hemostat that is applied topically to stop bleeding during surgery. Its active ingredient is recombinant human thrombin ("rThrombin") and the product is indicated as an aid to hemostasis whenever control of bleeding by standard surgical techniques (such as suture, ligature, or cautery) is ineffective or impractical. Recothrom is part of a class of surgical hemostats commonly referred to as "active" hemostats. Other classes of surgical hemostats include mechanical hemostats, flowable hemostats and fibrin sealants. Recothrom was approved in the United States in January 2008 and in Canada in December 2010.
