Alchemia (aussie company) and Dr. Reddy's are teaming up to make Arixtra generic (it's been off patent for a few years). They announced today that their plant will be inspected in Novmeber, so maybe next year? Further, Arixtra is now indicated for treatment of DVT. ACS is pending, I gather, dunno the odds there. Obviously, still not an immediate concern, but a bit mores so than it was at the time of this post to which I am replying.
