Off-label use of drugs in pediatrics: a scoping review
European Journal of Pediatrics(2022)
摘要
To explore the current state of research on off-label drug use in children and identify the existing research gaps in this topic. Six literature databases were searched to identify studies focusing exclusively on off-label drug use in children (aged < 18 years) published in Chinese or English between 2016 and 2021. We also searched clinicaltrials.gov for pediatric clinical trials conducted in the same period and compared the numbers of studies on off-label use and clinical trials for the most commonly reported drugs and drug types. Our search revealed 568 studies on off-label drug use. Almost half of the studies ( n = 240) were cross-sectional. A total of 212 specific drugs or drug types were addressed in 361 studies, the most frequent being antipsychotic agents ( n = 12), dexmedetomidine ( n = 10), and rituximab ( n = 8). Antipsychotic agents were also the most common type of drug examined in clinical trials in children. We identified a total of 435 different types of off-label use, the top three being unapproved indication ( n = 157), population ( n = 96), or age ( n = 36). Only about one-third of the studies reported collecting informed consent ( n = 195) or having ethics committee approval ( n = 166). Conclusions : Off-label use of antipsychotics in children is widely reported in the literature. We suggest pediatric researchers to consider the number of studies on off-label use and existing clinical trials on different drugs when selecting target drugs for new studies and systematic reviews. What is Known: • There exist a large number of studies on off-label drug use in children. What is New: • This is the first scoping review of studies on off-label drug use in children. • Off-label use of antipsychotic agents is widely reported.
