Outside of the hospital, the most commonly used anticoagulants are warfarin Coumadinwhich can be taken by mouth, and a group of drugs called low molecular weight heparins LMWHof which enoxaparin Lovenox is a common example.
Medications That Prevent Blood Clots Anticoagulant medicines are used to keep blood clots from forming in the arteries or veins or prevent existing clots from growing larger.
Although anticoagulants are sometimes called blood thinners, they do not actually thin the blood. The job of anticoagulants is to promote the smooth flow of blood and prevent clotting in blood vessels.
These drugs are used to prevent heart attacks, strokes, and blood clots in the leg veins deep venous thrombosis or lungs pulmonary embolism in people at high risk for developing these blockages.
Clots can block blood flow to the heart muscle resulting in a heart attack or the brain resulting in a stroke. The main types are warfarin, heparins, factor Xa inhibitors, and thrombin inhibitors. These agents work in different ways to keep blood from clotting.
They do not break up blood clots that have already formed, but prevent new clots from forming or growing larger. Patients for whom anticoagulants are prescribed include those with heart disease, clotting problems, a history of strokes, recent surgery, or blood vessel blockages or inflammation that cannot be treated using other therapies.
Administration of Anticoagulants Anticoagulants are given either in oral form or by injection.
Most injectable forms are administered in the hospital. The type of anticoagulant prescribed depends upon the condition being prevented.
Oral anticoagulants are used to ward off clot formation in patients with heart-valve replacement, atrial fibrillation, or other heart diseases, and in patients with phlebitis inflammation of a vein. Injectable anticoagulants are often used to prevent blood clots before or after major surgery, such as knee or hip replacement.
Anticoagulants are powerful medications, and the dosage must be monitored closely. If the dosage is too high, bleeding can result, but if the dosage is too low, blood clots can occur. Patients who are taking anticoagulants on a long-term basis are required to have regular prothrombin time PT blood testing.
The PT test measures a value of clotting time that indicates whether the dosage of anticoagulant should be adjusted. Frequent blood tests are not required with some newer types of anticoagulants, however.
Side Effects Common side effects of anticoagulants include stomach upset, loss of appetite, bloating, and diarrhea.
If the dosage is too high, blood may be seen in the urine or stool or around the gums, or frequent nosebleeds may occur. These side effects, as well as easy bruising, dark stools, itching or hives, vomiting of blood, or back pain, should be reported to a healthcare professional immediately.
Many foods and drugs can increase or decrease the action of anticoagulants, especially warfarin. Patients should be aware of the foods that can interfere with anticoagulants and should avoid eating them often or in large quantities.
Newer agents, however, have fewer dietary restrictions.
Patients should inform their pharmacist and doctors that they are taking an anticoagulant.Anticoagulants are considered to be one of the most at risk classes of medication for adverse events. In fact, in U.S. emergency departments anticoagulants accounted for 33% of adverse drug events in the elderly, and approximately 34, medication errors are reported yearly in long-term care.
Anticoagulant drugs have been available for more than 50 years (Schulman, ). Anticoagulation therapy: reinforcing patient education. Weiler's group also discovered a danger of APC'S anticoagulant effect Mice infected with Staphylococcus aureus all died from sepsis, despite treatment .
Direct oral anticoagulants (DOACs), a newer class of oral anticoagulants, have been promoted as a safer and more effective option than warfarin. Analysts sought to characterize the types of events that occurred with these medications, identify contributing factors, and describe system-based risk.
Medications. Various types of medications may be used in the treatment of DVT.
Although anticoagulants (blood thinners) do not destroy the clots, they may keep the clot from growing and other clots from forming. Anticoagulants are used to treat deep vein thrombosis, pulmonary Find the Lowest Price Cancel. HEPARIN is an anticoagulant. It is used to treat or prevent clots in the veins, arteries, lungs, or heart.
5 Common Medications That Can Kill. July 13, As a class of medications, anticoagulants are used in therapy for thrombotic disorders. Oral anticoagulants (OACs) are taken by many people in pill or tablet form, and various intravenous anticoagulant dosage forms are used in hospitals.
Some anticoagulants are used in medical equipment, such as test tubes.
