Naproxen absorption in children

Area of Science:

• Pediatric Rheumatology
• Pharmacokinetics
• Drug Safety

Background:

• Rheumatic disorders affect children, requiring effective pain management.
• Naproxen is a common nonsteroidal anti-inflammatory drug (NSAID) used for rheumatic conditions.
• Pediatric dosing and pharmacokinetics for naproxen suspension require specific investigation.

Purpose of the Study:

• To evaluate the pharmacokinetic profile of naproxen in children.
• To determine peak plasma levels and plasma curves of naproxen in pediatric patients.
• To assess the suitability of naproxen suspension for treating rheumatic disorders in children.

Main Methods:

• A single oral dose of naproxen suspension was administered to 9 children (mean age 10.8 years) with rheumatic disorders.
• Peak plasma levels and plasma curves of naproxen were measured.
• Data were analyzed to compare pediatric pharmacokinetics with adult data.

Main Results:

• Naproxen exhibited no significant difference in peak blood levels and half-life between children and adults.
• The naproxen suspension formulation was well-tolerated in the pediatric participants.
• No adverse effects were observed during the study.

Conclusions:

• A twice-daily dosage regimen of naproxen, similar to adults, is likely suitable for children.
• Naproxen suspension demonstrates favorable safety and pharmacokinetic profiles in pediatric patients with rheumatic disorders.
• This study supports the therapeutic use of naproxen suspension in pediatric rheumatology.
