This book is based on the core module of pharmacy syllabi recognise by the A.I.C.T.E and various Technical Universities. This book is going to helpful to the students for various competitive examination including GPAT and NIPER.The material in this text covers basic terminology, principles and fundamental concepts of pharmacy so UG and PG students as well as pharmacy professionals shall be benefited by this book. I have tried to make a compact book instead of the bulkier one. To keep the size of the book, this book do not cover the detail syllabus of all subjects but only covers the most important topics and phenomena of respected subjects. Book contains the flow chart like presentation of topics, so that it can be easily grasped by students and they can quickly study and revised the important topics of various subjects of pharmacy.
