    AbstractProton-pump inhibitors (PPI) are empirically used to treat asthma symptoms such as cough; however, the effectiveness of PPI on asthma exacerbation has not been well studied. We aimed to evaluate the relationship between PPI use and asthma exacerbation using a large administrative claims database in Japan. We conducted a self-controlled case series using the JMDC Claims Database (JMDC, Inc., Tokyo, Japan). The cases included adult patients with asthma who were prescribed PPI and experienced at least one outcome event between January 2015 and December 2019. The primary outcome was the composite outcome of hospital admissions and unscheduled outpatient clinic visits due to asthma exacerbation. We also conducted stratified analyses based on PPI generation, the presence of gastroesophageal reflux disease (GERD), asthma severity, and the number of allergic comorbidities. A total of 7379 eligible patients were included in the study. PPI prescription was associated with a decrease in the composite outcomes (incidence rate ratio, 0.90; 95% confidence interval, 0.87-0.93). However, PPI prescriptions did not affect the outcomes of hospital admissions (incidence rate ratio, 1.34; 95% confidence interval, 0.86-2.10). Stratified analyses based on PPI generation, the presence of GERD, asthma severity (except for severe asthma), and the number of allergic comorbidities yielded consistent results. PPI use was associated with a moderate decrease in asthma exacerbation, regardless of the patient profile. However, this effect was not as strong as the prevention of hospital admissions, and outcome events were not prevented in patients with severe asthma.© 2024.
