Abstract

Public policy tries to promote appropriate drug use by allowing firms to market drugs in interstate commerce only for uses that the Food and Drug Administration has found to be safe and effective. Because of their medical knowledge, physicians are authorized to prescribe drugs even for uses unapproved by the FDA. Nevertheless, physicians have relied on drug firms for information on appropriate prescribing despite the inherent tension between drug firm dissemination of information to promote sales and rational prescribing. In the past, physicians often relied particularly on drug firm advertising for information on drug use. Today, physicians rely on drug firms to finance continuing medical education. A historical review reveals connections between these two different ways commercial interests have influenced the information that physicians receive and points the way to needed reforms.
