Is pediatric labeling really necessary?

Labeling refers to the label on the drug container and all printed materials, including the package insert, that accompanies the product. Labeling of a drug indicates that there is substantial evidence from adequate and well controlled clinical trials for the safe and effective use of that drug. Labeling provides important information on clinical pharmacology, indications and usage, contraindications, precautions, adverse effects, dosage, and administration. Unfortunately for children, most drug labeling contains the precautionary disclaimer, because safety and efficacy in children have not been established. The availability of safe and effective drugs has been directly responsible for the improvement in health over the past 50 years. Children essentially have been excluded from the benefit of the many therapeutic advances that have marked pharmaceutic drug development. The failure to include children in clinical trials during drug development leads to delay in implementing potentially effective treatment. Most US food and Drug Administrationapproved drugs lack approval for use in all children or are restricted to certain pediatric age groups, primarily older children.1 Only a few of the new drugs released in this country each year are approved for use in children. This lack of information on the safe and effective use of drugs in the most vulnerable patients, infants and neonates, is of greatest concern. Only five of the 80 most frequently used drugs have been approved for use in this population. Another problem is that most drugs are not available in suitable pediatric dosage forms. They are not available in appropriate dosage sizes, lack liquid formulation, and taste peculiar to the child, making compliance difficult. Pharmacies extemporaneously prepare many drugs in liquid dosage forms for use in children. These dosage forms are not sufficiently tested to determine stability, efficacy, or expiration dating. For solid dosage forms, parents often must divide adult tablets in halves or quarters to get an appropriate dose for their child. This results in imprecise dosing that can lead to poor therapeutic response. Practitioners are left to use empiric therapy in treating their pediatric patients because of the inadequate information available for prescribing of drugs. They often must choose between not treating children with potentially beneficial medications because they are not approved for use in children, or to treat them with these medications based on adult studies and limited or anecdotal experience in children. In either case, children may not be prescribed optimal therapy.
