Textbook of Pathophysiology (As per PCI): An Essential Guide for Pharmacy and other Paramedical Courses is the first edition of the book. The etiopathogenesis of diseases and disorders is emphasized. The author's goal in writing this book was to meet the demands of pharmacy college lecturers and students. Not just pharmacy students, but also medical and paramedical students, are intended readers. They'll learn about the etiology, pathogenesis, pathology, and pathophysiology of illnesses, as well as clinical manifestations and therapeutic options. This book will come in handy as a quick reference and refresher material for readers. Pharmacy students, in particular, would appreciate the book's structure and scope as a resource for understanding pathophysiology. I am confident and certain that the authors will find their endeavor fruitful because they have accomplished everything they hoped for and expected from this book.
