One of the first anticoagulants, warfarin, was initially approved as a rodenticide. (wikipedia.org)
Common anticoagulants include warfarin and heparin. (wikipedia.org)
Newer non-vitamin K antagonist oral anticoagulants appear to have fewer life-threatening bleeding events compared to warfarin. (wikipedia.org)
Warfarin is the anticoagulant of choice for venous thromboembolism (VTE) treatment, although its suppression of the endogenous clot-dissolution complex APC:PS may ultimately lead to longer time-to-clot dissolution profiles, resulting in increased risk of re-thrombosis. (ebi.ac.uk)
The anticoagulant warfarin (Coumadin, Jantoven) is used to prevent blood clots from forming or to prevent existing clots from getting larger. (healthline.com)
Anticoagulants, such as heparin or warfarin (also called Coumadin), slow down your body's process of making clots. (medlineplus.gov)
For many years, the only available oral anticoagulant was warfarin , a vitamin K antagonist that was very effective at preventing strokes but that comes with a high risk for bleeding, including intracranial hemorrhage and fatal bleeding. (medscape.com)
The introduction of the direct-acting anticoagulants (DOACs) a few years ago was a step forward in that these drugs have been shown to be as effective as warfarin but are associated with a lower risk of bleeding, particularly of intracranial hemorrhage (ICH) and fatal bleeding. (medscape.com)
John Alexander, MD, professor of medicine at Duke University Medical Center, Durham, North Carolina, a researcher active in this area, notes that "while the DOACs cause less bleeding than warfarin, they still cause two or three times more bleeding than placebo, and there is a huge, unmet need for safer anticoagulants that don't cause as much bleeding. (medscape.com)
Non-vitamin K anticoagulants can be associated with lower kidney damage when compared to warfarin in atrial fibrillation patients, found a new study published in Journal of the American College journal. (medindia.net)
Their study, published online today in the Journal of the American College of Cardiology, is the most recent in a series of studies seeking to determine the safety and efficacy of non-vitamin K antagonist oral anticoagulants versus the long-standard warfarin. (medindia.net)
However, our findings indicate that the non-vitamin K antagonist oral anticoagulants as a group are associated with less injury to kidneys than warfarin. (medindia.net)
These patients had atrial fibrillation and started taking oral anticoagulants -- apixaban, dabigatran, rivaroxaban or warfarin -- sometime between Oct. 1, 2010, and April 30, 2016. (medindia.net)
However, the researchers took it a step further and separated out the patients taking non-vitamin K antagonist oral anticoagulants from those taking warfarin. (medindia.net)
Since non-vitamin K antagonist oral anticoagulants have a different drug mechanism than warfarin, researchers have hypothesized that non-vitamin K antagonist oral anticoagulants may be related to better renal outcomes. (medindia.net)
Patients with nonvalvular atrial fibrillation can certainly be switched from warfarin therapy to a NOAC or a DOAC (direct oral anticoagulant). (ajmc.com)
Is there a difference in efficacy and safety among new oral anticoagulants compared to warfarin in subgroups of patients with atrial fibrillation (Afib)? (the-hospitalist.org)

This detrimental effect might not occur during VTE treatment using other anticoagulants, such as rivaroxaban or enoxaparin, given their different mechanisms of action within the coagulation network. (ebi.ac.uk)
Ideally, all patients who can benefit from using an anticoagulant, i.e. with a CHA 2 DS 2 -VASc score ≥ 2 for females or ≥ 1 for males, should either be prescribed a DOAC (i.e. dabigatran or rivaroxaban) or have a documented reason why not. (bpac.org.nz)
A retrospective analysis of Medicare patients who started an anticoagulant and then amiodarone found that they had a 44% increased risk for bleeding-related hospitalization compared to those on other antiarrhythmics and that this risk was higher with rivaroxaban than apixaban. (acpinternist.org)
They noted that this risk was most pronounced in patients who were receiving rivaroxaban or had known risk factors for hemorrhagic complications of anticoagulant treatment. (acpinternist.org)

Anticoagulants are closely related to antiplatelet drugs and thrombolytic drugs by manipulating the various pathways of blood coagulation. (wikipedia.org)
