“…These results directly support the claims of proponents of DTCA of pharmaceuticals who state that advertising increases public knowledge of different health conditions and their management. 5,18,20,35 Importantly, this is the first study to demonstrate this effect of DTCA of GERD medications, which constitute a significant share of the drug advertising market. 36 Despite its findings, this study had some limitations.…”

Background: The use of direct-to-consumer advertising (DTCA) to promote sales of overthe-counter (OTC) pharmaceuticals used to manage common medical conditions, such as gastroesophageal reflux disease (GERD), is increasing. However, the educational value of these advertisements as well as the public perceptions of this type of advertising remain largely unknown among non-English speaking populations. Objective: The aim of this study was to explore the public perceptions and educational value of a short motion graphic video documenting the lifestyle of person with GERD and presenting a brief introduction to the role of proton pump Inhibitors (PPIs) in relieving the symptoms. Methods: This was a prospective quasi-experimental study in which a short mock advertising motion graphic video was shown to a sample of adult individuals in malls and shopping centers in different cities across Saudi Arabia. Participants were required to express their levels of agreement with six statements concerning their perceptions of DTCA of OTC drugs, and answer a quiz consisting of three questions and enquiries about their knowledge of GERD and the OTC drugs used in its treatment. Results: Two hundred and ninety-five participants were involved in this study, the majority of whom were female (55.30%). After watching the video, the percentages of participants who strongly agreed or agreed that DTCA is a credible source of information and encourages them to purchase the marketed drug have increased significantly (P<0.05). With regard to the quiz, the percentages of participants with correct answers regarding the definition of GERD, knowledge of OTC drugs for GERD, and awareness of the common side effects of PPIs increased from 81.69% to 95.93%, 69.83% to 96.27%, and 46.44% to 91.53%, respectively (P<0.0001). Conclusion: DTCA of OTC drugs for GERD, particularly if the content complies with the regulatory requirements, can promote the public knowledge of the disease and treatment options.
