This drug is usually used to prevent clotting during surgery. Because they are new to the market, they are considerably more expensive than Coumadin. One advantage of these drugs is that no testing is necessary. Initially these drugs had no antidote, but in 2018 an antidote was released to the market, helping to alleviate some safety concerns. Drugs in this category all have names ending in "xaban." As the name suggests, they inhibit an enzyme called factor X. These are fairly new drugs, including Xarelto ( rivaroxaban ) and Eliquis ( apixaban ). Home monitoring may be available, or it may be done in a clinic. This monitoring can lead to adjustments, either in drug dosage or in diet (eat more or fewer leafy green vegetables, which contain Vitamin K). Warfarin requires monitoring with a blood test, approximately on a monthly basis. An antidote (used if major bleeding occurs) thus is Vitamin K. They act by inhibiting Vitamin K, which is necessary for clotting. These are the most widely used anticoagulants and much is known about them. Coumadin (warfarin) and similar drugs.There are currently four major groups of anticoagulants: This means that there are many potential ways of limiting clotting. It surprises many, but the risk of stroke is still considerable in patients who have had afib or flutter in the past.Ĭlotting involves a sequence (cascade) of chemical reactions. This is also true for those who have a history of atrial fibrillation or flutter. To be clear, those with artificial valves need to take anticoagulants for the rest of their lives. This includes atrial fibrillation, atrial flutter, and having artificial heart valves. They prevent new clots from forming or existing ones from increasing in size.Īnticoagulants are often prescribed for those with a history of certain conditions to reduce the risk of stroke. They are used in HCM mainly to reduce the danger of stroke among those with atrial fibrillation, atrial flutter, or artificial valves.Īnticoagulants make it harder for blood to clot. Overview: Blood thinners (anticoagulants) make it harder for blood to clot.
