Being a basic subject of Medical Sciences large number of books are available on this subject that give minute details in voluminous form. We felt it necessary to scan the voluminous information and gather the relevant information that may cater to the needs of students of first year Bachelor of Pharmaceutical Sciences. Though in general, this book may prove useful to the students of Pharmacy, Nursing and other Paramedical Sciences; in particular it complies with the requirements of First Year B. Pharm. students. We shall highly appreciate constructive suggestions including criticism from the readers.
