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.




Drug Metabolism


Book Description

Clinical Manual of Drug Interaction Principles for Medical Practice


Book Description

Drug interactions have become a significant iatrogenic complication, with as many as 5% of hospitalizations and 7,000 deaths annually attributable to drug-drug interactions in the United States. There are several reasons these numbers have increased. First, many new medications have been brought to market in recent years. Second, advances in medical care have resulted in increased longevity and more elderly patients than ever before -- patients who are more likely to be following polypharmacy regimens. Population patterns in the U.S. have amplified this trend, with aging baby boomers swelling the patient pool and demanding treatment with medications advertised on television and in print. Fortunately, drug interactions can be prevented with access to current, comprehensive, reliable information, and the Clinical Manual of Drug Interaction Principles for Medical Practice provides just that in a user-friendly format psychiatry clinicians (including residents and nurses) and forensics experts will find indispensable. With this new edition, the book has evolved from "Concise Guide" to "Clinical Manual" and offers the expanded coverage and features healthcare providers need to keep up with this critical field. The book is well organized, with major sections on metabolism; cytochrome P450 enzymes; drug interactions by medical specialty; and practical matters, such as the medicolegal implications of drug-drug interactions and how to retrieve and review the literature. In the section on P450 enzymes, each chapter addresses what the individual enzyme does and where, its polymorphisms, and drugs that inhibit or induce activity. Each chapter also includes extensive references and study cases to help the reader understand and contextualize the information. A number of additional features enhance the book's scope and utility: The book boasts the very latest information in the area of drug metabolism, transport, and interaction. The chapter on P-glycoprotein (a drug transporter) was expanded from the last edition to include a broader array of transport mechanisms. The highest ethical standard was adhered to in the development of this volume, which was not supported in any way by pharmaceutical makers or distributors. All eight contributors to this excellent resource are experts in the fields they have addressed, and clinicians can trust that the information contained in the Manual reflects the very latest research. This exceptionally practical manual is essential to maintaining the highest standard of care.

Pharmacology in 7 Days for Medical Students


Book Description

Pharmacological knowledge among medical students can have a very short 'half life': students often fail not because they have failed to study, but because they have been unable to retain key knowledge and reproduce it in an exam setting. This book takes an alternative route to the conventional approach of comprehensively exploring each individual drug and its features: not only can such an approach overwhelm and make knowledge retention difficult, but the current exam format makes questions structured in this way unlikely anyway. Instead of aiming to be completely comprehensive, it examines drugs systematically by classifications, mechanisms of action, therapeutic uses and side effects, enabling students to gain the distilled, functional grasp of pharmacology that their exams actually demand quickly and clearly.
