They have a rapid onset and offset of action. This means it is often possible to pause them 12 to 48 hours before surgery and resume them shortly after the surgery. By contrast, warfarin and phenprocoumon are often paused up to a week before surgery, and low-molecular-weight heparins are used to "bridge" the therapy gap, typically for several ...
The p-methoxy group of apixaban connects to S1 pocket of FXa but does not appear to have any interaction with any residues in this region of FXa. The pyrazole N-2 nitrogen atom of apixaban interacts with Gln-192 and the carbonyl oxygen interacts with Gly-216. The phenyl lactam group of apixaban is positioned between Tyr-99 and Phe-174 and due ...
Apixaban is recommended by the National Institute for Health and Clinical Excellence for the prevention of stroke and systemic embolism in people with non-valvular atrial fibrillation and at least one of the following risk factors: prior stroke or transient ischemic attack, age 75 years or older, diabetes, or symptomatic heart failure.
Peak-to-trough ratio in pharmacokinetics is the ratio of peak (C max) and trough (C min) levels of a drug over its dosing interval (τ) at steady state.. Peak-to-trough ratio (PTR), also known as peak-to-trough variation or peak-to-trough fluctuation, is a parameter in pharmacokinetics which is defined as the ratio of C max (peak) concentration and C min (trough) concentration over a dosing ...
In 2009 the sponsor for the phase 3 trial pulled out, where cangrelor was being tested against placebo. Cangrelor development was halted for a time when the sponsor pulled out after the interim analysis review committee (IARC) decided that the trial wouldn't show the "persuasive" clinical efficacy that is need for regulatory approval.

An anticoagulant, commonly known as a blood thinner, is a chemical substance that prevents or reduces the coagulation of blood, prolonging the clotting time. [1] Some occur naturally in blood-eating animals, such as leeches and mosquitoes, which help keep the bite area unclotted long enough for the animal to obtain blood.
Betrixaban (trade name Bevyxxa) is an oral anticoagulant drug which acts as a direct factor Xa inhibitor. [1] Betrixaban is FDA approved for venous thrombosis prevention in adults hospitalized for an acute illness who are at risk for thromboembolic complications. [2]
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.
