Until the 1990s, it was generally accepted that medicines were first developed for adults and their use in children was investigated later, if at all. One of the main tasks of hospital pharmacies was the manufacturing of child-appropriate formulations in a more or less makeshift way. The first change came in 1997 with U.S. legislation that rewarded manufacturers to do voluntary pediatric research. Ten years later, the European Union passed legislation that required manufacturers to discuss all pediatric aspects, including formulations, with the regulatory authorities as a condition of starting the registration procedure. In consequence, manufacturers must now cover all age groups, including the youngest ones. So far, pediatric formulations were more a focus for academic researchers. Through the changed regulatory environment, there is now a sudden high commercial demand for age-appropriate formulations. This book begins by highlighting the anatomical, physiological and developmental differences between adults and children of different ages. It goes on to review the existing technologies and attempts to draw a roadmap to better, innovative formulations, in particular for oral administration. The regulatory, clinical, ethical and pharmaceutical framework is also addressed.

Klappentext
As the first book that specifically addresses pediatric formulations in the context of drug development, Pediatric Formulations: A Roadmap covers anatomy and physiology of children as well as the technical state of the art, gives hints about where to find inspiration, and provides a suitable background on the regulatory framework. Existing books on pediatric formulations mainly discuss compounding at the pharmacy. This is not a how to formulate textbook for pharmaceutical scientists; the subtitle A Roadmap indicates that we are on a path in largely unexplored territory. It is an attempt to equip the reader with necessary information on how to get started with the appropriate mindset. Among medicinal specialties, pediatrics is a young discipline. The potential dangers of medicine were often underestimated in earlier times. Cough suppressants labeled as suitable for children and adults a hundred years ago could kill children as they contained opioids. Since then, a complex framework has evolved, with physicians, pharmacists, drug development companies, generic companies, academic scientists, regulatory authorities, reimbursement organizations, patients and children's parents as key players. The position of children in our society has changed dramatically during the last century. Children were protected against clinical trials, yet thanks to clinical trials, many more children with cancer survive today. The development of age-adjusted drug formulations is not only a technical challenge. For new drugs today, there are laws both in the United States and the European Union that compel the research-based pharmaceutical industry to also consider children during drug development. One of the major demands of authorities is the development of age-appropriate formulations.Daniel Bar-Shalom is an Associate Professor in Drug Delivery at The Faculty of Health and Medical Sciences, University of Copenhagen.
