A quick lesson in Rx pharma pricing tactics: As a drug manufacturer, when you are giving up on a product, you raise the price dramatically. If you know that the scripts are going away, you try to grab as many dollars for every unit you can. Not only that, but you can let the distributors (McKesson, Cardinal, etc.) know ahead of the price increase and get them to buy a bunch of product at the old price. That helps juice the sales numbers that the company is reporting to investors and Wall Street.
That is why Pernix has jacked the price of Zutripro.
