Pharmacotherapy of pediatric lung disease: differences between children and adults
1College of Pharmacy, University of New Mexico, Albuquerque.
Insights
Pediatric drug dosages differ from adults due to physiological development, often requiring higher weight-based doses. Accurate drug administration in children necessitates specialized equipment like syringe infusion pumps for effective therapeutic monitoring.
Area of Science:
- Pediatric pharmacology
- Pharmacokinetics in children
- Drug administration in pediatrics
Background:
- Pediatric drug dosages significantly differ from adult dosages due to developmental physiological variations affecting drug absorption, distribution, and clearance.
- Infants and children generally require higher therapeutic agent dosages on a weight basis compared to adults.
- Parenteral drug administration in pediatric patients is complicated by slow fluid infusion rates.
Purpose of the Study:
- To highlight the complexities of drug administration in pediatric populations.
- To emphasize the importance of accurate drug monitoring and dosage adjustments in children.
- To discuss challenges in aerosol drug delivery and the impact of pulmonary diseases on drug disposition in pediatrics.
Main Methods:
- Review of physiological differences impacting drug pharmacokinetics in pediatric patients.
- Analysis of challenges in parenteral and aerosol drug administration techniques for infants and children.
- Examination of the influence of chronic and acute pulmonary diseases on drug disposition in pediatric populations.
Main Results:
- Pediatric patients often require higher weight-based drug dosages.
- Syringe infusion pump devices are critical for accurate drug monitoring and dosage adjustments in pediatrics.
- Aerosol administration in pediatrics presents significant challenges, including coordination with inhalation and drug loss in endotracheal tubes.
- Pulmonary diseases like cystic fibrosis can alter drug disposition and metabolism, requiring further study in children.
Conclusions:
- Drug dosages and administration methods must be carefully considered in pediatric patients due to unique physiological factors.
- Specialized equipment and techniques are essential for safe and effective drug therapy in infants and children.
- Further research is needed to fully understand the impact of disease states on pediatric pharmacokinetics and optimize drug treatments.
Abstract:
Drug dosages for infants and children differ significantly from those used in adults (Table 5). This is due to normal developmental physiologic differences that affect absorption, distribution, and clearance. In general, infants and children require higher dosages of many therapeutic agents on a weight basis. Parenteral drug administration difficulties are complicated by the slow fluid infusion rates often used in infants and young children. The use of syringe infusion pump devices is critical for accurate therapeutic drug monitoring and dosage adjustment in pediatrics than in adults. Aerosol administration in pediatrics is more complicated and is poorly studied. Difficulty with coordinating metered-dose aerosols with inhalation and drug raining out on small endotracheal tubes of ventilated patients are two significant problems. Chronic and acute pulmonary disease can significantly affect drug disposition and metabolism, but has been poorly studied in children. The pharmacokinetics of a number of drugs have been evaluated in cystic fibrosis and may provide insight into the effect of disease states on drug disposition.
