heparin
heparin (hep-er-in) n. an anticoagulant produced in liver cells, some white blood cells, and certain other sites, which acts by inhibiting the action of the enzyme thrombin in the final stage of blood coagulation. An extracted purified form of heparin is widely used for the prevention of blood coagulation both in patients with thrombosis and similar conditions and in blood collected for examination. It is administered by injection; the most important side-effect is bleeding.
low-molecular-weight h. a type of heparin used to prevent deep-vein thrombosis following surgery or during kidney dialysis. It is more readily absorbed and requires less frequent administration than standard preparations.
