Evithrom (Omrix), a blood-clotting protein used to help control bleeding during surgery, is the first human thrombin approved since 1954.
Evithrom is indicated when control of bleeding by standard surgical techniques is ineffective or impractical. The productis applied to the surface of bleeding tissue. It may also be used in conjunction with an absorbable gelatin sponge. Evithrom must not be injected into blood vessels.
In a clinical trial, it was comparable to cattle-derived thrombin in both safety and effectiveness.
