Thrombin is a blood-clotting enzyme that helps the body form clots to stop bleeding. It is produced by the activation of prothrombin, a precursor enzyme found in the blood. Thrombin helps to form fibrin, a fibrous protein that forms the mesh-like structure of a clot. Thrombin also activates other clotting factors such as Factor XIII, which helps to strengthen the clot. Thrombin is used in medicine to treat patients who have bleeding disorders or who need additional clotting factors. It is also used in surgical procedures to help stop bleeding and to prepare surfaces for suturing.
Thrombin is a protein substance naturally found in the blood. It is a key enzyme in the blood clotting process, also known as hemostasis . When a blood vessel is injured, platelets are activated and begin to clump together to form a plug. Thrombin helps in this process by converting fibrinogen, a soluble protein in blood plasma, into fibrin, an insoluble protein that forms the mesh of a blood clot
Thrombin is also used as a medication to promote blood clotting. It is available in topical forms (such as powder, fleece, or gel) to control bleeding from minor cuts, wounds, or nosebleeds. It can also be injected or applied directly to bleeding tissues during surgery.
