Michael Makris: Lower Bleeding Risk With Apixaban vs Rivaroxaban in Acute Venous Thrombosis
Michael Makris, Emeritus Professor of Haemostasis and Thrombosis at the University of Sheffield, shared a post on LinkedIn about a recent article by Lana Castellucci et al, adding:
“Important paper for clinical practice.
A large study, independent of the pharma industry, found that in the setting of acute venous thrombosis, the risk of clinically relevant bleeding was:
- 3.3 percent with Apixaban
- 7.3 percent with Rivaroxaban
This difference was significant.
Congratulations to Lana Castellucci for coordinating this multicentre study.
We await the results of their AF study with interest.
Considering how many patients worldwide are on these drugs, this will be an impactful study.
The attached figure gives the summary.
The original article in this week’s New England Journal of Medicine is behind a paywall.”
