Compared to the risk of bleeding with warfarin use, direct factor Xa inhibitors have a higher risk of GI bleeding, but lower risk of bleeding in the brain. [2] Other side effects may include stomach upset , dizziness , anemia or increased blood levels of liver enzymes .
Dabigatran is an oral direct thrombin inhibitor. Dabigatran (Pradaxa) was found to be noninferior to Warfarin in prevention of ischemic stroke, as well as intracranial hemorrhage risk and overall mortality for non-valvular atrial fibrillation according to the RE-LY trial.
The study found that dabigatran had comparable rates of ischemic stroke or systemic embolism, intracerebral haemorrhage, and all-cause mortality when compared to other anticoagulants like apixaban, edoxaban, and rivaroxaban. Notably, apixaban was associated with a lower risk of gastrointestinal bleeding than dabigatran and the others.
ELIQUIS ® (apixaban) Demonstrated Superiority In Reducing A Composite Of Recurrent Venous Thromboembolism And All-Cause Death Without Increasing The Rate Of Major Bleeding Versus Placebo During ...
Apixaban and other anticoagulants (dabigatran, edoxaban and rivaroxaban) appear equally effective as warfarin in preventing non-hemorrhagic stroke in people with atrial fibrillation and are associated with lower risk of intracranial bleeding. [18] [19] While apixaban may be used in people with severely decreased kidney function and those on ...
U.S. FDA Approves ELIQUIS ® (apixaban) to Reduce the Risk of Stroke and Systemic Embolism in Patients with Nonvalvular Atrial Fibrillation ELIQUIS Demonstrated Superior Risk Reductions Versus ...
Factor Xa was identified as a promising target for the development of new anticoagulants in the early 1980s. In 1987 the first factor Xa inhibitor, the naturally occurring compound antistasin, was isolated from the salivary glands of the Mexican leech Haementeria officinalis. Antistasin is a polypeptide and a potent Xa inhibitor.
Haemorrhage (internal bleeding) is the most prominent side effect of blood-thinning therapy. [36] Concomitant use of drugs that increase the risk of bleeding is not recommended. Meanwhile, patients should receive education about proper management of cuts, bruises and nosebleeds. The agents can be classified according to different mechanisms of ...
