I have pubmeded Bovine thrombin+coagulopathy and many articles come out. If ZGEN sales rep can show this journal articles to doctors, I think it will be a strong case. I agree its not a significant problem because the rate of coagulopathy is so low, but how is paying 14 bucks more going to hurt the profit for the hospital? I am sure if KG aggresively cuts its price for multi year contracts, ZGEN will do the same too.
