Treating pediatric depression in primary care: coping with the patients' blue mood and the FDA's black box

Treatment of Major Depressive Disorder in Pediatric Populations

Major depressive disorder (MDD) is a severe illness that afflicts about 16.6% of people over their lifetime. MDD is highly correlated with suicidality, and often first presents in adolescence. Unfortunately, many pediatric patients suffering from MDD go undiagnosed, and current evidence-based treatment options in the U.S. are limited to psychotherapy and two selective serotonin reuptake inhibitors approved by the United States Food and Drug Administration. Molecular mechanisms have been shown to play a role in MDD pathogenesis, progression, and response to medication, yet few studies have explored the role of these pathways in pediatric MDD. In this review, we outline the gravity and importance of MDD in pediatric patients, some challenges in diagnosis and treatment, current treatments available for pediatric patients, and research to investigate differences between pediatric and adult MDD. We hope that this review will provide an outline of the current understanding and treatment of MDD in pediatric patients, and provide thoughtful insights for future work that could advance our understanding of MDD in pediatric populations, and also identify new therapeutic strategies.

Impact of FDA Actions, DTCA, and Public Information on the Market for Pain Medication

Nonsteroidal anti-inflammatory drugs (NSAIDs) are one of the most important classes of prescription drugs used by primary care physicians to manage pain. The NSAID class of products has a somewhat controversial history, around which a complex regulatory and informational environment has developed. This history includes a boxed warning mandated by the Food and Drug Administration (FDA) for all NSAIDs in 2005. We investigate the impact that various information shocks have had on the use of prescription medications for pain in primary care in the USA. We accomplish this by extracting data on nearly 600,000 patients from a unique nationwide electronic medical record database and estimate the probability of any active prescription for the four types of pain medications as a function of FDA actions, advertising, media coverage, and patient characteristics. We find that even after accounting for multiple sources of information, the FDA label changes and boxed warnings had a significant effect on pain medication prescribing. The boxed warning did not have the same impact on the use of all NSAID inhibitors. We find that the boxed warning reduced the use of NSAID COX-2 inhibitor use, which was the focus of much of the press attention. In contrast, however, the warning actually increased the use of non-COX-2 NSAID inhibitors. Thus, the efficacy of the FDA's black box warning is clearly mixed.
