Zohydro is not making any money. This drug was supposed to make $300 million per year but they are only making $5 million. Some states like Mass banned the drug from being sold there. I wonder if the patents are of any help at all.
Shorting PTX is the best option. From $12 to $0.50. Shorts win. This is officially and pinkie penny stock. They are manipulating it to avoid delisting but it will never work. Increase in debt and decrease in revenues is enough to know where this is headed.
