Risk of Neuropsychiatric Diseases According to the use of a Leukotriene Receptor Antagonist in Middle-Aged and Older Adults with Asthma: a Nationwide Population-Based Study Using Health Claims Data in Korea

BACKGROUND

Although a leukotriene receptor antagonist (LTRA) is an effective drug for asthma, there has been increasing concern regarding neuropsychiatric (NP) adverse reactions. However, evidence for this association is not sufficient, especially in adults.

OBJECTIVE

To investigate the association between the use of an LTRA and the risk of developing NP diseases in adults with asthma.

METHODS

We performed a nationwide, retrospective, cohort study using data from the National Health Insurance Service-Health Screening Cohort (NHIS-HEALS). We selected asthma patients with no previous use of an LTRA, and NP outcomes were defined by the registration of certain International Classification of Diseases, 10th Revision codes (F00-F59) during follow-up. We obtained the hazard ratio (HR) for NP diseases according to the use of an LTRA.

RESULTS

Overall, 61,571 asthma patients without LTRA experience were enrolled, and 12,168 of them took an LTRA during the follow-up period. In the adjusted model, the HR for newly diagnosed NP diseases showed no significant difference according to use of an LTRA (HR 1.01; 95% confidence interval 0.83-1.23; P = .952). Subgroup analysis for associations between duration of LTRA use and risk of NP disease indicated no significance for all groups (<6, 6 to <12, 12 to <24, and ≥24 months). Common NP diseases included dementia (75.4% vs 76.1%), mood disorders (12.68% vs 12.80%), and panic disorders (5.63% vs 3.53%) in LTRA users and non-LTRA users, respectively, and there was no significant difference in the prevalence of each NP disease in either group.

CONCLUSIONS

The current study showed the use or duration of LTRA exposure was not associated with the occurrence of NP diseases in Korean adult asthmatics.
