I didn't understand from the article why, if this drug has been around for 60+ yrs., there aren't lots of generic versions of it. How can they keep the exclusive patent on it for so long? If the profits really go to developing even better drugs, then it's probably a good thing. If no one else wants to bother making a generic because there's no money in it, then what we're seeing is the market at work. No one invests in a pharma company because they want to save the world; they do it to make money.
