This book is not meant to be an alternative to time-tested exhaustive textbooks on drug doses, but meant to be a concise companion for all health professionals dealing with pediatric population on day-to-day basis because it is humanly not possible to remember the wide range of medications currently used in pediatrics. In this edition, existing drugs are updated and expanded, a few drugs are omitted, and many more drugs and useful tables are added. In this edition, the advice of several readers and their suggestions have been incorporated.
