Mazou Ngou Temgoua: Why Does Apixaban Cause Less Bleeding than Rivaroxaban?
Mazou Ngou Temgoua, Contract hospital practitioner at Châteauroux-Le Blanc Hospital Center, shared on LinkedIn about a recent article by Lana A. Castellucci et al, adding:
“Why does apixaban cause less bleeding than rivaroxaban?
A recent trial in VTE shows a lower incidence of bleeding with apixaban compared to rivaroxaban.
But the real question lies elsewhere:
Where does this difference come from?
Several avenues:
1. Pharmacokinetics
- Apixaban is given in 2 doses – more stable concentrations
- Rivaroxaban in 1 dose – higher plasma peaks
2. Intensity of factor Xa inhibition
A more ‘smoothed’ inhibition could further preserve physiological hemostasis
3. Induction Diagram (highlighted in this article)
- 7 days for apixaban
- 21 days for rivaroxaban
Are we really comparing two molecules… or two anticoagulation strategies?
Key Message:
- If the difference is related to the schema, it is potentially modifiable.
And this opens up a simple question:
Should we rethink the initial phase of rivaroxaban in VTE?
The answer is not yet known.
But the debate deserves to be asked.
And you, what is your reading?”
