Applied Dermatotoxicology: Clinical Aspects provides concise, systematic, and state-of-the-art information on the toxicological effects of substances on skin, and recent advances in dermal toxicity testing. This book specifically addresses the clinical presentations borne out of exposure to a variety of chemicals. It begins with an overview of skin biology to provide toxicologists with a basic understanding of its anatomy and physiology. Next it presents a variety of dermatotoxicological effects, as well at the toxic agents that cause them, with color photographs to illustrate these effects. Applied Dermatotoxicology: Clinical Aspects is an essential reference for toxicologists in industry, and for those medical professionals who encounter cases of dermal exposure to toxic agents. - A concise, yet inclusive review of effects of chemical exposure - Includes background on basic skin biology - Provides vital clinical reference for toxicologists in non-clinical settings

This work presents and evaluates methods employed to identify the potential of certain types of chemicals to adversely affect the skin. A variety of test methods are included such as tests for skin penetration, metabolism, irritation, the skin immune system, photo effects, skin cancer, and topical effects of retinoids and depigmenting chemicals. Tests for chemicals that affect the reproductive and nervous system are also included. Both animal and human tests that have been standardised and tests that are under development and employ animal alternatives are addressed in this book. Besides different testing methods, a rationale for accepting non-animal models and a review of some regulatory agency discussions about animal alternative tests are included.

Principles of Toxicology concisely and efficiently presents the scientific basis for toxicology as it applies to the workplace and the environment, covering diverse chemical hazards encountered in modern workplaces and natural environments and providing a practical understanding of these hazards for those concerned with protecting the health of humans and ecosystems. The work presents not only theory, but also practical information regarding chemical hazards to give the student and new professional a working knowledge of the practice of toxicology and the ability to solve problems in environmental and industrial settings. Case histories and examples from industrial and environmental exposures to chemicals are included to demonstrate the application of toxicological principles. To allow for seamless reader comprehension and further exploration of covered topics, the work is supplemented with numerous illustrations to clarify and summarize key points, as well as annotated bibliographies. In the 4th edition, all chapters and references have been updated to account for the latest scientific thinking, and new color figures have been added. New topics covered in 4th Edition of Principles of Toxicology include: Regulatory toxicology, including the key regulatory framework in which much of the field of toxicology operates Alternative methods in toxicology, including cutting-edge approaches to developing new information on the toxicity of drugs and chemicals The dilemma of selecting safe exposure limits, guiding readers through practical considerations and pitfalls in developing and using safe exposure limits Ecological risk assessment, with detailed discussion of methods and considerations when evaluating the effects of contaminants on plants and animals. Providing information on the principles of toxicology and the application of those principles to solve problems in environmental and industrial settings, Principles of Toxicology serves as an excellent textbook resource for advanced undergraduate, graduate, and professional students in a range of environmental and health fields. It is also valuable to health professionals who need toxicological information and assistance beyond what is found in an introductory text to general toxicology.
Many aspects of drug safety have become an outstanding and even persistent issue and may occur during the process of both drug discovery and development. Until 15 years ago, drug discovery and evaluation was primarily a sequential process starting with the selection of the most pharmacologically active compound from a series of newly synthesized small molecule chemical series by means of distinctive pharmacological assays. Safety aspects were addressed by evaluation of the selected compound at high doses in a series of specific studies directed at indications other than the intended indication of the new compound. These tests are then followed by pharmacokinetic studies, which are primarily conducted to confirm whether the selected compound possesses a suitable half-life for sufficient exposure and efficacy and, whether it has the desired properties specificity to the intended route of administration. Safety aspects relied predominantly on the conduct of single and repeat toxicologydose studies, which inform changes in organ structure rather than organ function. Both toxicological and pharmacokinetic studies are adapted to the progress of studies in clinical pharmacology and clinical trials. The new edition of this well and broadly accepted reference work contains several innovative and distinguished chapters. This "sequential" strategy has been abandoned with this new version of the book for several reasons: - Of the possible multitude of negative effects that novel drugs may impart on organ function, e.g. ventricular tachy-arrhythmia, many are detected too late in non-clinical studies to inform clinicians. On the other hand, negative findings in chronic toxicity studies in animals may turn out to be irrelevant for human beings. - New scientific approaches, e.g. high-throughput screening, human pluripotent stem cells, transgenic animals, knock-out animals, in silico models, pharmaco-genomics and pharmaco-proteomics, as well as Artificial Intelligence (AI) methods offered new possibilities. - There are several examples, that show that the "druggability" of compounds was considerably underestimated when the probability of success of a new project was assessed. The success rate in the pharmaceutical industry and the introduction of new chemical entities to the market per year dropped dramatically, whereas the development time for a new compound increased, sometimes exceeding the patent protection. Research and development scientists, involving the following changes, therefore adopted a change of strategy: - Parallel instead of sequential involvement of the various disciplines (multidimensional compound optimization). - The term "Safety Pharmacology" was coined. The International Conference on Harmonization (ICH) founded a Safety Pharmacology Working Group and the Safety Pharmacology Society (SPS) was launched. The discipline provided for evaluation, development and validation of a multitude of safety tests outlined in the 'Core Battery of Studies'. - Characterizing the exposure profile of a drug by conducting pharmacokinetic studies that evaluates the absorption, distribution, metabolism and excretion should to be investigated at an early stage of development as results contribute to the selection of a compound for further development. Advancements in Toxicology were achieved by the introduction of new methods, e.g., in silico methods, genetic toxicology, computational toxicology and AI. The book is a landmark in the continuously changing world of drug research and developments. As such, it is essential reading for many groups: not only for all students of pharmacology and toxicology but also for industry scientists and physicians, especially those involved in clinical trials of drugs, and for pharmacists who must know the safety requirements of drugs. The book is essential for scientists and managers in the pharmaceutical industry who are involved in drug discovery, drug development and decision making in the development process. In particular, the book will be of use to government institutions and committees working on official guidelines for drug evaluation worldwide.
