The great barrier belief: The blood-brain barrier and considerations for juvenile toxicity studies.
Reproductive Toxicology 2017 September
Juvenile animal studies can be warranted to support the development of pediatric medicines. Drugs acting on the CNS or those which penetrate into the brain merit particular attention. The blood-brain barrier is functionally mature at birth, but undergoes functional postnatal modulation to provide a suitable microenvironment for the developing brain. In the past, dosing in rat juvenile studies has often commenced at 4 or 7days of age. However, rodents are very neurologically immature at birth compared with humans. We suggest that dosing of rat pups below two weeks of age is generally not warranted for the assessment of pediatric drugs. In the rare circumstances where exposure of younger rats is required to address a particular concern (e.g., an indication in preterm babies), consideration should be given to likely misleading signals of toxicity arising from high brain penetration of the drug, which may not be predictive for the human.
