 About The Book  

The content area is reorganized as per the PCI and is exclusively meant for B. Pharmacy and Pharm.D course requirements. The focus includes applications of physicochemical properties of drug molecules, dosage forms and clinical implications. Drug absorption and evaluation of dosage forms are given adequate stress along with associated properties.

The book involves the quantification of drug in different processes, such as absorption, distribution, biotransformation and excretion. Several these aspects are important in the clinical situations. This is a basic level book which is normally important for third/final year of B. Pharm. course. These topics are so important that at PG level also these are included. The students of IV year, Bachelor of Pharmacy have been expressing the need for a simple book. This book will help learning calculating the pharmacokinetics parameters.

The book is broadly divided into Biopharmaceutics part and Pharmacokinetics part. Special emphasis is given to include the following:
     1. Conceptualisation of principles.
     2. Applications of principles.
     3. A number of illustrations.
     4. Question bank.
