Off‑label and unapproved pediatric drug utilization: A meta‑analysis.

Abstract

Despite legislative enforcement on authorized drugs, off-label and unapproved pediatric drug use is prevalent. The present study aimed to assess the global prevalence of off-label and unlicensed prescriptions among hospitalized children via meta-analysis. A comprehensive examination of articles published between 1990 and 2023 from the PubMed, Scopus, Excerpta Medica Database, Web of Science and Google Scholar databases was conducted. Key word-based advanced searches were executed using the aforementioned databases. A total of 45 studies that reported the prescriptions of off-label and unlicensed drugs to pediatric patients were included. The global prevalence of off-label and unlicensed drug prescriptions to children in pediatrics or neonatal departments was 56%. Patient sample sizes varied from 40-13,426, with a range of 240-8,891 total prescriptions issued. Of the 45 studies examined, 22 studies originated from Europe, 13 from Asia, 3 from South America, 3 from Africa, and 2 each from North America and Australia. Africa had the highest prevalence rate at 66%, followed by Asia, South America, North America, Australia and Europe. The present meta-analysis demonstrated that the prevalence of off-label and unlicensed drug prescriptions given to pediatric patients was notably high and geographically diverse. Therefore, drug authorities should standardize pediatric prescription practices in future.
