Heparins
Heparins
Heparins (pronunciation: /ˈhɛpərɪn/) are a group of anticoagulant medications. They are used to prevent and treat blood clots in the veins, arteries, and lungs.
Etymology
The term "heparin" comes from the Greek word "hepar", which means liver. This is because it was first isolated from dog liver cells in the early 20th century.
Types of Heparins
There are two main types of heparins: Unfractionated Heparin (UFH) and Low Molecular Weight Heparin (LMWH).
- Unfractionated Heparin (UFH) is a fast-acting blood thinner that is usually given by injection into a vein. It works by preventing the formation of blood clots.
- Low Molecular Weight Heparin (LMWH) is a type of anticoagulant that is given by injection under the skin. It is used to prevent and treat blood clots in the veins, especially in patients who have had surgery or who are at risk of blood clot formation.
Uses
Heparins are used in the prevention and treatment of various conditions such as Deep Vein Thrombosis (DVT), Pulmonary Embolism (PE), and in patients undergoing certain types of surgery to prevent clot formation.
Side Effects
Like all medications, heparins can cause side effects. The most common side effect is bleeding. Other side effects can include Thrombocytopenia (low platelet count), Osteoporosis (bone thinning), and Heparin-induced Thrombocytopenia (HIT).
