Yes Ash multi-billion market and if approved ZSAN will be the go to treatment for Migraine. How much extra will someone pay for rapid relief?? 30%-40% more? ZSAN could easily see sales of several hundreds of Millions per year. As I said before I see the odds very high that P3 is a success. Its not a new drug to prove, just the method of absorption. Again ZSAN has already demonstrated the ability to do this in previous trials.
That small float is going to make this thing fly with a little volume.
