• Study description:
  In this observational study (NCT01744301), patients aged 20–84 years in 2005–2011 were identified from The Health Improvement Network. The relative risk of seizure associated with use of proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2RAs) in a general population was quantified, overall and stratified by epilepsy status, and the effects of demographics and comorbidities were determined. In a nested case–control analysis, seizure cases were matched to controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using unconditional logistic regression. Estimates were adjusted for potential confounders.
