Spielberg, professor of pediatrics, pharmacology and toxicology at Dartmouth Medical School, and principal investigator for the Institute for Pediatric Innovation's Pediatric Pharmaceutical Reformulation Project, joins host Dr. Bill Rutenberg to discuss some of the challenges ahead: formulation, dosing, preservation, delivery and beyond.
