The pharmacokinetics of antiviral therapy in paediatric patients

Area of Science:

• Pharmacology
• Pediatric Medicine
• Infectious Diseases

Background:

• Optimizing drug dosage is crucial for effective treatment, especially in pediatric patients.
• Pediatric drug dosing is challenging due to pharmacokinetic variability, growth, and organ development.
• Lack of specific pediatric pharmacokinetic studies complicates accurate dosing.

Purpose of the Study:

• To review factors and misconceptions in determining optimal drug dose and administration routes for pediatric populations.
• To discuss pharmacokinetics, appropriate doses, and preferred routes for specific antiviral drugs used in children.

Main Methods:

• Literature review of factors affecting pediatric drug dosing.
• Analysis of pharmacokinetic data for selected antiviral medications.
• Discussion of administration routes and dosages for treating herpesvirus infections in children.

Main Results:

• Identified key factors influencing pediatric drug pharmacokinetics and dosing.
• Summarized appropriate doses and preferred routes for aciclovir, ganciclovir, famciclovir, foscarnet, and cidofovir.
• Highlighted common misconceptions in pediatric drug administration.

Conclusions:

• Accurate pediatric drug dosing requires careful consideration of individual patient factors and drug-specific pharmacokinetics.
• Optimized dosing strategies are essential for effective herpesvirus treatment in children.
• Further research on pediatric pharmacokinetics is needed to improve treatment outcomes.
