Drug advertising may not increase prescriptions

摘要

Companies that advertise prescription drugs directly to consumers may not get as much bang for their buck as they - or their critics - assume.rnDirect-to-consumer advertising (DTCA) of drugs is only permitted in the US and New Zealand and has long been controversial. Both proponents and opponents assume the ads increase prescriptions, with the former arguing they benefit society by raising awareness of diseases andrnavailable treatments and the latter that they pump up demand for drugs unnecessarily. However, DTCA is usually accompanied by other marketing directed at doctors, making it difficult to tease out the effects of the ads alone.
