Preclinical data
Do you know how the dose for children is being estimated based on preclinical data?
Expert
There are numerous ways of estimating children's doses from preclinical (that is, adult) data - frequently depends on the therapeutic index of drug in question (that is, the wider the therapeutic window the lesser accurate the child's dose requires to be). At times straight weight-basis that is, 7kg child gets 1/10 dose of the 70kg adult.
More accurately it is a dose based on the body surface area (that is, child's surface area is bigger in proportion to its body weight as compare to adult). There are normograms to evaluate surface area from height and weight of child.
All of such might be wrong when clearance of drug in child is considerably dissimilar from adult example: distinct metabolism or various route of clearance.
