Anticoagulant therapy uses drugs that reduce the blood's ability to clot, given to prevent and treat conditions such as deep vein thrombosis, pulmonary embolism, ischemic stroke, and clot formation associated with atrial fibrillation and mechanical heart valves. Physiologist Jay McLean discovered heparin's anticoagulant activity in 1916 while a medical student at Johns Hopkins, and warfarin, first developed and marketed in the 1940s as a rodenticide, entered clinical use as an anticoagulant drug in humans in the 1950s and remained a mainstay of long-term anticoagulation for decades. Beginning in the 2010s, a newer generation of direct oral anticoagulants came into wide use, offering more predictable dosing than warfarin without the need for the frequent blood monitoring warfarin therapy requires.

Frequently Asked Questions
What do anticoagulants do, and what is their main risk?
They prevent dangerous clots; the main risk is bleeding.
An anticoagulant, commonly known as a blood thinner, is a chemical substance that prevents or reduces the coagulation of blood, prolonging the clotting time. Anticoagulation therapy prevents the formation or growth of dangerous clots. The most serious and common adverse side effects associated with anticoagulants are increased risk of bleeding, both nonmajor and major bleeding events. This record describes what the sources state and is not medical advice.
What are the main types of anticoagulant?
Warfarin, heparin and the direct oral anticoagulants.
Warfarin (Coumadin) was found to be the anticoagulant most prescribed in a large multispecialty practice. Heparin is the most widely used intravenous clinical anticoagulant worldwide. The direct oral anticoagulants (DOACs) were introduced in and after 2008.
