Kaphingst and DeJong provide an excellent overview of the educational potential of direct-to-consumer advertising (DTCA) of prescription drugs. We concur with the results of
the study and would like to provide two additional sources of data that may enhance the decision making process by the FDA to develop policy guidelines.
First, we would like to point out a study that was conducted to evaluate the inconsistencies in DTCA practices by manufacturers.[1] A content analysis of all print DTCA published in the National Geographic from January 2000 to October 2003 was performed; it identified 128 advertisements. We noticed two formats used for brief summaries. The older, more cluttered version was predominantly used (56.25%). A few manufacturers
had voluntarily adopted a new version sometime during the year 2000, which appears slightly better based on visual judgment, due to the increased font size and print formatting. Although a few companies had adopted the new
version, they did not do so for all their products. In
addition, the trend analysis indicated that the use of the new format fluctuated over the years, with a drop of 14% in 2001 and a respective drop of 18% in 2002. The question that seems to arise is, Do these new print DTCA summaries by being user-friendly induce positive attitudes toward the product, thus leading consumers to request more information
regarding such drugs from manufacturers, physicians, or pharmacists?
To answer this question, pharmacy students (N = 147) in an experimental, randomized study evaluated four formats of DTCA brief summaries.[2] These formats included the two existing formats, those reported as old (format A) and the new version (format B) in the above mentioned study, and two new formats developed based on previous research and FDA proposed guidelines for nonprescription drug labels (format C) as well as brief summaries (format D).[3] It was found that format C, developed based on similar formatting design principles as those seen on the nonprescription drug
labels (Drug Facts panel), was perceived to be more easy to use, had the most favorable attitude towards the product, and received the highest score for satisfaction with the information provided. The overall rank received for superiority was format C, followed by format D (which was based on FDA guidance on brief summary format), format B (new version currently in use), and format A. Formats currently in existences received very low scores, with the worst scores predominantly seen for format A.
We hope that this new information provides the FDA with the needed direction toward developing guidelines for DTCA print summaries that would enhance the educational potential of DTCA.
