The second edition of Pharmacology for Pharmacy Students has seen the light of the daymuch earlier than expected. It happens to be a small source of personal solace at the heights
of COVID crisis across the world.All chapters are thoroughly revised, keeping in mind B Pharm, D Pharm, and Pharm D
students. Topics on ‘biologics and biosimilars’ and treatment of heavy metal poisoning, havebeen added. The syllabus of Pharmacy Council of India is covered in entirety and the chaptersare arranged semester-wise. More flowcharts, figures and mnemonics are added.
Hope this book makes learning pharmacology easy and pleasurable.It was a pleasant surprise to receive positive feedback both from the students and staff
from across the country and abroad through mail.Please continue to send your valuable feedback to [email protected]

Preface to the Second Edition
Pharmacists play a major role in drug development. In fact, they are involved in the entireprocess of drug use right from research, development, manufacture, storing and reaching
it to the patient. Hence extensive knowledge of pharmacology is needed for effective andappropriate functioning in their career.
However, since there are multiple subjects to be covered in a relatively short span duringtheir course, it is necessary to simplify the subject. Books in pharmacology meant only forpharmacy students are hard to find. Hence, to reduce the burden of the students, this bookhas been published exclusively for the pharmacy students.
The Pharmacy Council of India has revised the syllabus for pharmacy and also made itsemester-wise. The latest syllabus of PCI is covered and the chapters are arranged as persemester sequence. Flowcharts, tables and figures have been used all through the book forbetter understanding. Compare and contrast tables help in better retention of the topics.
Pharm D a recently introduced course in pharmacy, also brings with it various challengesof training the students to attain the objectives of the syllabus. Extensive knowledge ofpharmacology is mandatory and the subject is spread out through the course. Pharmacologyfor Pharmacy Students, covers the topics prescribed for Pharm D students too. Many collegeshave already prescribed Medical Pharmacology for Pharm D students and may now alsofind this book useful.
Hope this book makes reading pharmacology a pleasurable experience.
