Pharmacoepidemiology is concerned with the study of the uses of drugs and their effects in specific populations. It builds on the principles of pharmacology and epidemiology. Drug safety is a significant area of pharmacoepidemiology. It studies the adverse effects of drugs. It is concerned with the assessment, detection, monitoring and prevention of adverse drug reactions. Overdose, misuse and abuse of drugs as well as drug exposure during critical stages of human life such as pregnancy and breastfeeding, are also studied in this field. This book aims to shed light on some of the unexplored aspects of drug safety and pharmacoepidemiology. It strives to provide a fair idea about these disciplines and to help develop a better understanding of the latest advances within these fields. Students, researchers, experts, pharmacologists and all associated with these fields will benefit alike from this book.
