Meta AnalysisPediatric intravenous paracetamol (propacetamol) pharmacokinetics: a population analysis.
The aim of this study was to describe propacetamol pharmacokinetics in children in order to predict concentrations after a standard dosing regimen of propacetamol 30 mg x kg(-1) (15 mg x kg(-1) paracetamol) 6 h. ⋯ A mean paracetamol serum concentration of 10 mg x l(-1) is achieved in children 2-15 years given a standard dose of propacetamol 30 mg x kg(-1) 6 h. This concentration in the effect compartment is associated with a pain reduction of 2.6/10 after tonsillectomy and provides satisfactory analgesia for mild to moderate pain. Clearance is reduced in children less than 1 year of age and the target concentration of 10 mg x l(-1) may be achieved by scaling this standard dose regimen using predicted clearance in this younger age group.
