Since introduction of the EU Paediatric Regulation in January 2007 the development and the life cycle of a drug in pre- and post-authorisation period has changed significantly. Pharmacovigilance science has traditionally been a discipline focussed on the post-marketing or post-authorisation period, with due attention directed towards pre-clinical safety data, clinical trials and adverse events. As the biological sciences have evolved, pharmacovigilance has slowly shifted toward earlier, proactive consideration of risks and potential benefits of drugs in the pre- and post-approval stages of drug development, leading to a maturing of drug safety risk management. The development of drugs for the paediatric population has changed the awareness that not only the safety issues need to be thoroughly investigated for a safe treatment of the children. In conjunction with the knowledge about efficacy, pharmacokinetic/pharmacodynamic and the age appropriate formulation for the concerned drug, the impact on the aim to apply safe medicines for children will steadily increase. Therefore, a proposal for a joint effort performing clinical research and appropriate drug development and clinical trials in children needs a strong support from a number of stakeholders like Clinical Trial Network, Paediatric Society, pharmaceutical industry and authorities.
