Safety of Proton Pump Inhibitor in Paediatrics: A Study Based on EudraVigilance Data
Abstract
Background and objectives: Despite limited paediatric approvals, the use of proton pump inhibitors (PPIs) among children has increased in recent years, and concerns have arisen about their safety, including the risk of allergies. To provide additional evidence on the paediatric safety of PPIs, we performed a study on suspected adverse drug reactions (ADRs) in clinical practice.
Methods: We retrieved from EudraVigilance reports of suspected ADRs for PPIs in the age class 0-11 years in the period 2003-2022. Most reported ADRs and allergic conditions were evaluated by descriptive analysis. A case-non-case analysis was performed using reporting odds ratio (ROR) with a 95% confidence interval (CI). Chi-square or Fisher's exact tests were used to detect differences in reporting rates.
Results: A total of 1389 reports and 4157 suspected ADRs were analysed. Most reports involved omeprazole (46.9%) and esomeprazole (27.3%), and 75.8% concerned serious outcomes. Gastrointestinal disorders were among the most common suspected ADRs, with vomiting being the most frequently reported (2.3%). Among allergic conditions, there were six cases of toxic epidermal necrolysis, five of Stevens-Johnson syndrome and four of drug reaction with eosinophilia and systemic symptoms. Statistically significant reactions for omeprazole were choking (ROR 5.54; 95% CI, 1.04-29.56) and pneumonia (3.61; 1.41-9.20), while for esomeprazole gastrointestinal disorder (7.57; 1.18-48.60) and constipation (4.74;…
