A placebo-controlled model for assaying systemic analgesics in children

Area of Science:

• Pediatric Pharmacology
• Pain Management
• Clinical Trial Methodology

Background:

• Assessing analgesic efficacy in children requires validated pain models.
• The sore throat pain model offers a potential method for evaluating systemic analgesic agents in pediatric populations.

Purpose of the Study:

• To evaluate the sore throat pain model's sensitivity in assessing systemic analgesic agents in children.
• To compare the efficacy of ibuprofen and acetaminophen against a placebo for treating acute sore throat pain in children aged 2 to 12 years.

Main Methods:

• A double-blind, placebo-controlled, single-dose parallel study involving 116 children (2-12 years) with acute sore throat.
• Participants received ibuprofen (10 mg/kg), acetaminophen (15 mg/kg), or placebo.
• Pain intensity and relief were assessed by children, parents, and pediatricians using validated scales over 6 hours.

Main Results:

• Both ibuprofen and acetaminophen demonstrated significantly greater efficacy than placebo in reducing sore throat pain, as rated by children, parents, and pediatricians (p < 0.05).
• Active treatments also significantly reduced elevated oral temperatures in children.
• No treatment-related adverse effects were reported.

Conclusions:

• The sore throat pain model is a sensitive and reliable assay for identifying analgesic activity in children.
• Ibuprofen is confirmed as an effective analgesic for treating acute sore throat pain in pediatric patients.
