Carl over at No Oil For Pacifists does the simple research that the interviewed expert couldn't be bothered with. Let's bet that this won't stop Dr. Avorn from pontificating on the subject, though.
Interestingly, doctors are among the most irritated by pharmaceutical companies, and it seems directly tied to their disdain for the marketing. There is an assumption that medicine-makers should be devoted entirely to getting the best medicine to the patient, as they themselves theoretically are. A noble ideal, but I'm not sure it would lead to the continued medical improvements we count on.
