Well,
Here is how Lovenox to Arixtra conversion works.
OASIS V and VI has shown that 2.5mg Q24h Arixtra ($16 per dose contract pricing) was just as effective as 1mg/kg Q12h Lovenox in ACS, yet with less bleeding. 1mg/kg usually means 60mg, 80mg, or 100mg per dose of Lovenox. 80mg Lovenox usually costs around $40 - 45 per dose. So, if you convert to Arixtra for ACS, it's $16 per day vs. $100 per day. Huge huge savings. One concern is that Arixtra doesn't have a reversal agent while we can attempt to use Protamine for Lovenox reversal.
Now, cost savings from VTE prophylaxis won't have much impact...since 40mg Lovenox costs arond $20. Yet, better than nothing.
Let me know how you guys pull this off.
