The lack of availability of appropriate medicines for children is an extensive and well known problem. As a consequence off label or unlicensed administration of medicinal products in every day paediatric practice is frequent. A variety of obstacles hinder the development of paediatric indications for drugs primarily intended for the adult market. ⋯ The objective of the Paediatric Regulation is to improve the development of high quality and ethically researched medicines for children aged 0 to 17 years, to facilitate the availability of information on the use of medicines for children, without subjecting children to unnecessary trials, or delaying the authorisation of medicines for use in adults. The impact of the Paediatric Regulation reflects in an increase in the number of paediatric studies to be performed, even if a significant number of these studies have not started yet. The objective of this review is to describe the main regulatory and scientific features which play a role in the complex issue of paediatric drug development.
