The dosage of drugs which might be used in children must be determined to avoid empirical use, even when no application has been submitted for a paediatric licence. Toxicological evaluation and assessment of the effects on growth, an adapted pharmaceutical form and paediatric pharmacokinetic and adult clinical data are essential before conducting trials designed to determine the paediatric dosage. The dose used during preliminary studies is extrapolated from the adult dose expressed in relation to weight, tested in a dose-effect study, and then more accurately defined on the basis of pharmacokinetic data in different age groups. Obtaining consent from both parents for studies whose direct benefit is not always obvious, as well as the global cost of these studies, constitute drawbacks to paediatric drug development. Incentives to determine a paediatric dosage could consist of public participation in funding, prolongation of the patent, and granting an advantageous price for a specifically paediatric pharmaceutical form or indication.
