Doctors should question the value of most heavily promoted drugs

Research suggests that pharmaceutical promotion can lead to overprescription of brand-name medications. The study found that top-selling and top-prescribed drugs were more likely to be effective, safe, affordable, novel, and represent a genuine advance in treating a disease. However, heavily promoted drugs often fell short in these areas.
