Pharmacovigilance or drug safety may be defined as a science that relates to the "collection, detection, assessment, monitoring, and prevention" of side/adverse effects of drugs. It is also essential to monitor for adverse effects even after a drug or therapy has been on the market for some time, as new ones may emerge. This book addresses several fundamental issues in three major sections well-presented in easy-to-understand formats. The authors of this book contributed the latest research, and each chapter has been reviewed and updated to enhance the book's educational value, clarity, and readability.
