It is interesting how much business and politics factors into th availability of drugs on the market. Here is an example of how a major business move could impact influenza drugs on the market, hopefully driving down the price and increasing the amount of available drugs should an epidemic hit.
Fujifilm bought out Toyama Chemicals and is developing what hopefully will become a major competitor for Tamiflu in the next couple of years. This could be very helpful, considering that there is proven resistance to Tamiflu AND there probably won't be enough to go around. (The business folks are betting on the bird flu epidemic--a sure bet according to Dr. Bob.)
