Indication

Action

Heparin increases the action of factors in the body that normally prevent the formation of blood clots.
Normally there is balance between the factors in the body that create blood clots and those that prevent the formation of blood clots. In the settings of trauma, surgery and immobilisation there is an increased predisposition to blood clot formation in the body. By increasing the actions of the anti-clotting factors Heparin lessens the risk of the formation of new blood clots however it has no effect on blood clots that are already present in the body.
