Hi all,

Anglosaxon countries tend to use warfarin as the anticoagulant of choice.

But most other developed nations use Marcumar/Phenprocoumon.

Marcumar stays for a lot longer in your system (longer half life), so apparently INR can be very stable.

Does anybody know why anglosaxon countries seem to prefer Warfarin over Marcumar?

Thanks
Tommyboy

PS. I am asking because if Marcumar were to be clearly superior, I would consider asking my GP to let me switch

half life makes management easier and "withdrawl" for therapies easier (Elimination half-life is 6–7 days instead of more like 2 for warfarin).

Accordingly, something like this would be impossible under Phenprocoumon

further I think the effect of taking Grapefruit would take longer to subside.

Also unlike (say) Sintrom you aren't INR=1 the day after your forgot your dose.

Personally I feel that warfarin is the not too hot and not too cold, the Goldilocks anticoagulant.
