Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of the study is to define population pharmacokinetic parameters and variability factors for paracetamol and its metabolites in overweight and obese children compared to children with normal weight for age and sex.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will determine the pharmacokinetic parameters of paracetamol and its metabolites in overweight and obese children compared to children with normal weight for age and sex. The results will enable establishing dosage recommendations for paracetamol in overweight and/or obese children and adolescents.
