Prescription drug advertising and drug utilization: the role of Medicare Part D.
The purpose of this paper was to explore how direct-to-consumer advertising (DTCA) for prescription drugs affects use by leveraging a large and plausibly exogenous shock to DTCA influenced by the introduction of Medicare Part D. Part D led to greater increases in advertising in geographic areas with greater concentrations of Medicare beneficiaries. The researchers explored the effect of this increase in advertising on non-elderly individuals to separate the effects of advertising from the direct effects of Part D. The study found that exposure to advertising resulted in large increases in treatment initiation and improved adherence to medication. Advertising also had substantial positive spillover effects on non-advertised generic drugs.
