The introduction of the book "Industrial Pharmacy-I" makes me incredibly happy. This book's content has been painstakingly created to conform to the Pharmacy Council of India's prescribed curriculum for students pursuing a bachelor's degree in pharmacy. To make the subject easier for students to understand, an attempt has been made to research it using as simple a vocabulary as possible. Many images throughout the book, including flowcharts and diagrams, help students understand difficult concepts. The genuine hope of the author is that readers of this book, academicians and students alike, will find something of value. I'm hopeful that this book will be well received by both teachers and students. We are willing to consider suggestions about any and all facets of the industry. Any faults or deviations that may have gone unnoticed are entirely our fault, and we would be very grateful if readers could point them out to us if they did.
