Atrial Fibrillation is very common among Americana; it is the irregular rhythm of the heart usually present with or without symptoms. It causes the formation of clots, clots go to the brain and cause a stroke. Anticoagulants have been known for a few decades to cause abrupt decrease around 50%) in the rate of stroke and prevent clotting at the required location and can cause bleeding. Anticoagulants aims for the safeguard and therapy of thromboembolism to prevent stroke. Previously used Anticoagulants are Warfarin, low molecular weight heparin and heparin. There were shortcoming of the drugs like parenteral route of administration, requires frequent monitoring due to variability in response, the onset of action is slow and there is bleeding in response to the drugs .In addition to heparin and vitamin k antagonist, anticoagulants that act on enzymatic agility or vigor brought about by of thrombin and factor Xa was exquisitely formulated. Implementation of the foresaid oral Anticoagulants requires knowledge of necessitate the comprehension of discrete indication, contraindications, characteristics. Research and repeated clinical trials have led to acceptance of few newer drugs which are working classically styled but better than Warfarin. In the last few years, Pradaxa (dabigatran), Xarelto (rivaroxaban), and Eliquis (dabigatran) have all been authorised by the FDA (apixaban). All three are ‘blood thinners,’ like warfarin, that lessen the overall risk of stroke associated with atrial fibrillation while also causing bleeding.
