Angiomax, chemically, is a synthetic congener of the naturally occurring drug hirudin (found in the saliva of the medicinal leech Hirudo medicinalis).
Yes, off the top of my head;) Does not sound dissimilar to lovenox actually. It might not be so easy to genericize without MNTA like technology.
Does anyone know if angiomax has similar complexity to lovenox? Pig, leech, don't see much difference. Both biological. One from intestines, the other from saliva. At least it is not from the saliva (or derivative thereof) of a certain poisonous lizard, which may make another nice generic target in 8-10 years.
