A study that looked at Australian patients over a 15-year period found that regular use of aspirin was associated with an increased risk of age-related macular degeneration.
However a comment piece questioned whether the study had done enough to show that the association is causal.
Britain’s National Institute for Health and Clinical Excellence has recommended apixaban for the prevention of stroke and systemic embolism in some people with atrial fibrillation.
Aapixaban is a direct Xa inhibitor, and so does not require regular blood tests to monitor the blood’s clotting properties, unlike the most commonly used antithrombotic, warfarin.
