The review goes on to trace the development of Big Pharma's business model:
Develop or acquire a patented drug;
Forget further R&D as long as sales increase;
Identify a disease, real or imagined, which it treats but preferably doesn't cure for fear of cutting off a lifetime of sales;
Brand it for that condition;
Advertise the hell out of it, as ads are more important to sales than efficacy or developing new drugs;
Develop close competitor drugs to those which are very successful, like the more-than-10 anti-cholestoral drugs;
Ignore drugs for diseases which the rich world doesn't get.
There is more to the story, but that is enough for starters.
Here we have a hugely important and expensive industry that starts out with IP and then twists it to maximize profit. Business school students would regard that as highly innovative, but for the most part, what innovation there is doesn't benefit the consumer. The best I can say for it is that the ads pay for evening television news check them out.
