Low Molecular Weight Heparin (LMWH) is a type of anticoagulant medication derived from heparin, which is a naturally occurring substance in the body. LMWH is used to prevent and treat blood clots, particularly in patients undergoing surgery or those with certain medical conditions that increase the risk of clot formation. It works by inhibiting specific clotting factors in the blood, making it less likely for clots to form. LMWH is typically administered via injection and has a more predictable effect compared to standard heparin. This allows for easier dosing and monitoring, making it a preferred choice in many clinical settings. Common brand names include Enoxaparin and Dalteparin.
