Systematic assessment of opioid advertisements in general medical journals.

OBJECTIVE

To systematically examine the content of opioid-related advertisements.

DESIGN

Content analysis and quantitative assessment.

SETTING

North America.

PARTICIPANTS

Researchers examined advertisements in 2 issues per year from 1996 to 2016 of , the , and the .

MAIN OUTCOME MEASURES

Number of advertisements, nature of the claims made, and quality of cited evidence in the advertisements.

RESULTS

Opioid advertisements composed 89 of the 3173 pharmaceutical advertisements in 210 journal issues searched. Seventy-three advertisements were able to be obtained for analysis. Thirty-four (46.6%) did not mention the addictive potential of opioids, and 54 of 73 (74.0%) did not mention the possibility of death. All referenced studies in advertisements were funded by pharmaceutical organizations or had pharmaceutical company employees as authors. No advertisements cited high-quality evidence.

CONCLUSION

Many claims of the effectiveness and safety of opioids were published in medical journals through advertisements. Advertisements did not usually mention key negative information about opioids. Although the extent to which these advertisements directly influenced the development of the opioid crisis in North America is unknown, the marked omission of important detrimental effects of opioids may have played a role. Further efforts to restrict opioid marketing may be warranted.
