Low Molecular Weight Heparin (LMWH) Is a Class of Anticoagulant Medications

Low molecular weight heparin (LMWH) is derived from unfractionated heparin (UFH) by digestion or depolymerization of longer chains of heparin into shorter chains by chemical or enzymatic means. LMWH is used for prophylaxis of pulmonary embolism and deep vein thrombosis, or thrombosis occurring in a broad spectrum of clinical indications, including myocardial infarction, unstable angina, trauma, neurosurgery, and general or orthopedic surgery. Compared to UFH, low molecular weight heparin provides higher bioavailability after subcutaneous administration for thromboembolic indications. Moreover, LMWH eliminates the risk of crossing the placental membrane.

Low molecular weight heparin (LMWH) works by blocking the function of proteins called intercellular molecules. These are responsible for the formation of blood clots and foam cells. If these molecules are unable to perform their respective roles, clots will form in the blood vessels leading to various organs. Maintaining the efficiency of these cells in forming blood clots and foam cells by keeping them in the correct locations is a very important role of LMWH. As a result, Low molecular weight heparin should be used in very low doses and under strict medical supervision for patients with moderate to severe acute inflammatory conditions.

Moreover, low molecular weight heparin has been formulated to prevent or reduce blood clots when dissolved in the blood. These drugs are also known as anticoagulants are mostly used in the treatment of carotid artery thrombosis and the prevention of deep venous thrombosis and hemorrhage. The molecular weight of this drug is low, which enables it to be absorbed easily by the body. This type of blood thinner can provide more safety than other blood thinners. Due to its exceptional qualities, low molecular weight heparin has been preferred by many health care providers and patients alike. In the treatment of unstable angina and heart attacks, it is often given intravenously via a vein in the thigh or under the skin. 

For decades, low molecular weight heparin has been extensively used to treat various ailments. However, in recent years, because of its adverse effects, it has been replaced by several other non-steroidal anti-inflammatory substances, most of which carry very few side effects. Some of these include alginates, leupeptin, and methotrexate. For instance, methotrexate is the main component of many topical creams used to relieve pain due to rheumatoid arthritis. As it causes little pain, doctors often use it in conjunction with other drugs. However, low molecular weight heparin is not so safe, because it may increase the risk of bleeding and heart attack, especially in patients who already have cardiovascular problems.

The benefits of low-molecular-weight heparin are not without side effects. These side effects may include abdominal pain and nausea. Patients with liver disease should not use this form of heparin. Moreover, patients who are pregnant and nursing should also avoid LMWH, as well as patients should contact their physician before using this medication for any other reason. Low molecular weight heparin derivatives are characterized by marked anti-inflammatory effects and low anticoagulant activity that allow for these molecules to be viewed as a new class of non-steroidal anti-inflammatory drugs (NSAIDs).
