Heparin is a naturally occurring anticoagulant, meaning it helps prevent blood clots. It is commonly used in medical settings, especially during surgeries or for patients at risk of developing clots. Heparin works by inhibiting certain proteins in the blood that promote clotting, allowing for smoother blood flow.
There are two main forms of heparin: unfractionated heparin and low molecular weight heparin. Unfractionated heparin is typically administered through injections and requires careful monitoring, while low molecular weight heparin is easier to use and often given as a self-injection. Both forms are essential in managing various medical conditions related to blood clotting.
