Essentials of Biopharmaceutics and Pharmacokinetics - E-Book


Book Description

Essentials of Biopharmaceutics and Pharmacokinetics Kar’s Essentials of Biopharmaceutics and Pharmacokinetics deals with how a drug exerts its action in the human body through the fundamentals of absorption, distribution, metabolism and excretion. The book adopts a growth-oriented format and design that is developed systematically and methodically. The book interrelates five different sections: Section 1 Biopharmaceutics and Pharmacokinetics: What Do They Mean? Section 2 Biopharmaceutics Section 3 Pharmacokinetics Section 4 Clinical Pharmacokinetics Section 5 Bioavailability and Bioequivalence Each section starts with a basic theory and fields of application, focuses on model-independent pharmacokinetic analyses, expatiates various biopharmaceutical aspects of dosage form and evaluation, provides an altogether new approach in understanding both dosage regimen design and individualization, and explains modification in drug molecules related to the pharmacokinetics. Undoubtedly, the unique blend of fundamental principles and latest breakthroughs in the field will certainly provide sufficient subject matter to the students of pharmacy, pharmacology, medicinal chemistry scientists, who need a simple as well as detailed introduction in theory and application.







Modeling in Biopharmaceutics, Pharmacokinetics and Pharmacodynamics


Book Description

This book presents a novel modeling approach to biopharamceutics, pharmacokinetics and pharmacodynamic phenomena. It shows how advanced physical and mathematical methods can expand classical models in order to cover heterogeneous drug-biological processes and therapeutic effects in the body. Throughout, many examples are used to illustrate the intrinsic complexity of drug administration related phenomena in the human, justifying the use of advanced modeling methods.




Biopharmaceutics and Pharmacokinetics


Book Description

This book deals with the basics of the two disciplines of biopharmaceutics and pharmacokinetics. Different factors such as biological, physiochemical and formulation that influence the therapeutic efficacy of a drug are covered in biopharmaceutics. The absorption, distribution, metabolism and excretion of drugs are studied under this subject. Salient Features - Basics of biopharmaceutics and pharmacokinetics help to understand the various procedures and advances in drug design, product development, therapeutic drug monitoring, etc. - Pharmacokinetics covers the fundamentals of one compartment open model, multi-compartmental models. One compartment open model is presented in an elaborate manner to make the students familiar with various aspects of pharmacokinetics - Mathematical equations are developed using simple integration and differentiation methods - Practice problems are provided wherever necessary, and a question bank is included at the end of each chapter - Extreme care has been exercised to present the concepts in a simple way Second Edition includes - Application of principles in formulation development in industry for successful bioequivalence studies is included - One chapter on "In-vitro Dissolution Testing" is included to evaluate test formulations to chose right product for bioequivalence studies - A chapter on biostatistics with practice problems is included




Pharmacokinetic and Pharmacodynamic Data Analysis: Concepts and Applications, Third Edition


Book Description

This is a revised and very expanded version of the previous second edition of the book. "Pharmacokinetic and Pharmacodynamic Data Analysis" provides an introduction into pharmacokinetic and pharmacodynamic concepts using simple illustrations and reasoning. It describes ways in which pharmacodynamic and pharmacodynamic theory may be used to give insight into modeling questions and how these questions can in turn lead to new knowledge. This book differentiates itself from other texts in this area in that it bridges the gap between relevant theory and the actual application of the theory to real life situations. The book is divided into two parts; the first introduces fundamental principles of PK and PD concepts, and principles of mathematical modeling, while the second provides case studies obtained from drug industry and academia. Topics included in the first part include a discussion of the statistical principles of model fitting, including how to assess the adequacy of the fit of a model, as well as strategies for selection of time points to be included in the design of a study. The first part also introduces basic pharmacokinetic and pharmacodynamic concepts, including an excellent discussion of effect compartment (link) models as well as indirect response models. The second part of the text includes over 70 modeling case studies. These include a discussion of the selection of the model, derivation of initial parameter estimates and interpretation of the corresponding output. Finally, the authors discuss a number of pharmacodynamic modeling situations including receptor binding models, synergy, and tolerance models (feedback and precursor models). This book will be of interest to researchers, to graduate students and advanced undergraduate students in the PK/PD area who wish to learn how to analyze biological data and build models and to become familiar with new areas of application. In addition, the text will be of interest to toxicologists interested in learning about determinants of exposure and performing toxicokinetic modeling. The inclusion of the numerous exercises and models makes it an excellent primary or adjutant text for traditional PK courses taught in pharmacy and medical schools. A diskette is included with the text that includes all of the exercises and solutions using WinNonlin.
