I have worked with a lot of pharaceutical companies on many projects. One of their buggist concerns was that hey plow hundreds of millions of dollars into R&D, waiting 12 years for FDA approval, onlty to have an identical drug come out at 1/10th the price. I do not have the answer, I am not a phramacologist,; but you may want to Google anticoagulants, and discern if there is an equivalent drug that equals Plavix. I hope this helps. God Bless you. My Dad was in a similar situation before I understood the pharmaceutical business.
