Prescribing for children: issues in pediatric pharmacology
1Nurse Practitioner Program, George Mason University College of Nursing and Health Science, Fairfax, VA, USA.
Insights
Children metabolize and excrete drugs differently than adults due to developing body systems. This review explores pediatric pharmacokinetics, highlighting the need for more research and careful prescribing for optimal drug therapy in children.
Area of Science:
- Pediatric Pharmacology
- Clinical Pharmacy
- Drug Metabolism
Background:
- Children exhibit distinct physiological differences impacting drug response compared to adults.
- Infant and childhood development significantly alters drug absorption, distribution, metabolism, and excretion (ADME).
- Variations in gastrointestinal transit time and body composition are critical factors in pediatric pharmacokinetics.
Purpose of the Study:
- To explore pediatric pharmacokinetics and its clinical implications.
- To address the challenges posed by off-label medication use in children.
- To emphasize the importance of appropriate prescription writing and family education.
Main Methods:
- Review of pediatric pharmacokinetic principles.
- Discussion of developmental changes affecting drug disposition.
- Analysis of current challenges in pediatric drug prescribing.
Main Results:
- Significant pharmacokinetic variability exists in pediatric populations.
- Lack of specific pediatric dosage guidelines necessitates cautious prescribing.
- Off-label drug use is prevalent due to insufficient research.
Conclusions:
- Pediatric pharmacokinetics requires further extensive research.
- Clinicians must prioritize meticulous prescription writing and comprehensive family education.
- Enhanced understanding of parental education's impact on medication adherence is crucial.
Abstract:
Children and adults respond to drugs differently. There are important differences in the absorption, distribution, metabolism, and excretion of medications during infancy and childhood. Children's body systems are less developed; their gastrointestinal transit time varies; and their body composition changes with development. This article will explore pediatric pharmacokinetics, the effect the body has on a drug, and the implications for practice. The controversial off-label use of medications must be considered when prescribing medications because specific dosage guidelines for the pediatric population still are not available for the majority of marketed drugs. Prescription writing must be appropriate, legible, and meticulous. Family education about medications and administration techniques is an essential part of the clinician's role. The limited scope of current research in pharmacokinetics and the effects on the developing child creates the need for more studies on drug therapy and the pediatric client. Furthermore, clinicians need to expand research on the effects of parental education on accurate medication administration and drug therapy compliance.
