The use and effectiveness of pro re nata psychotropic medications in children and adolescents: A systematic review.

BACKGROUND

Published studies have not demonstrated the benefits of the practice of psychotropic PRN administration.

AIM

The goal of this study is to perform a systematic review on pro re nata (PRN) psychotropic medications administration in children and adolescents and examine the safety and effectiveness of this practice in child and adolescent psychiatric care units.

SETTINGS AND DESIGN

This is a systematic review.

MATERIALS AND METHODS

Several databases were searched till date. One hundred and sixty-five titles and abstracts were found and a total of 14 studies, for which most were retrospective, met the absolute criteria. The patients studied were children, adolescents and patients that presented to the emergency room or admitted as inpatient.

RESULTS

Indications for admission included aggression and agitation for all the studies. Most the medications used include haloperidol, olanzapine, diazepam, and risperidone. Commonly reported adverse effects following the administration of the PRN medications were sleepiness, acute dystonia, and drowsiness. The effectiveness of PRN medications, which was reported in four of reviewed studies, ranged from 30% to 50%.

CONCLUSION

Different effectiveness/outcome measures were used for all the studies; therefore, we could not generalize effectiveness across all the studies. Findings of the reviewed articles show the imperativeness of more research to evaluate the safety and effectiveness of PRN medications among child and adolescent populations.
