Weight-Adjusted Diclofenac Potassium Medicated Lollipop for Post-Adenotonsillectomy Pain in Children

This prospective single-arm pilot study evaluated a newly developed gelatin-based diclofenac potassium medicated lollipop intended for postoperative pain management after paediatric adenotonsillectomy. The pharmaceutical formulation was optimized through iterative development and characterized by physicochemical testing, content uniformity analysis, and microbiological quality assessment according to pharmacopeial standards.

Children aged 4 to 12 years undergoing elective adenotonsillectomy received weight-adjusted diclofenac potassium lollipops (15 mg, 20 mg, or 30 mg) administered every 8 hours during the first 24 postoperative hours. Pain intensity was assessed before and after each dose using age-appropriate validated pain scales. Secondary evaluations included product acceptability, requirement for rescue analgesia, and occurrence of adverse events.

The study was designed as an exploratory pilot investigation to assess the feasibility, pharmaceutical performance, preliminary clinical effectiveness, and safety of this novel paediatric drug-delivery platform, providing the basis for future randomized controlled trials and pharmacokinetic evaluation.
