Download or read book Predictive Methods in Percutaneous Absorption written by Gary P. Moss and published by Springer. This book was released on 2015-07-01 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book sheds new light on the development and use of quantitative models to describe the process of skin permeation. It critically reviews the development of quantitative predictive models of skin absorption and discusses key recommendations for model development. Topics presented include an introduction to skin physiology; the underlying theories of skin absorption; the physical laboratory-based processes used to generate skin absorption data, which is in turn used to construct mathematical models describing the skin permeation process; algorithms of skin permeability including quantitative structure-activity (or permeability) relationships (QSARs or QSPRs); relationships between permeability and molecular properties; the development of formulation-focused approaches to models of skin permeability prediction; the use of artificial membranes, e.g. polydimethylsiloxane as alternatives to mammalian skin; and lastly, the use of novel Machine Learning methods in developing the next generation of predictive skin permeability models. The book will be of interest to all researchers in academia and industry working in pharmaceutical discovery and development, as well as readers from the field of occupational exposure and risk assessment, especially those whose work involves agrochemicals, bulk chemicals and cosmetics.

Download or read book Skin Barrier written by Hans Schaefer and published by S. Karger AG (Switzerland). This book was released on 1996 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Skin Barrier is the first book to be written exclusively by researchers for researchers as a convenient desktop reference. It focuses on several key aspects of the skin barrier including composition and structure and a description of the properties governing the diffusion of compounds across the skin. Although there has been a large number of laboratories involved in measuring percutaneous absorption over the past 15 to 20 years, it is only recently that there has been a general consensus in the scientific community regarding the development of standard protocols. Recognizing the importance of this, the authors have included two chapters detailing the protocol used in measuring and predicting percutaneous absorption and a discussion on the practical application of these techniques to solve associated problems. In order to provide the researcher and especially the student with access to more detailed information, the book features a comprehensive listing of references published over the past 10 years. Skin Barrier is the only desktop reference for dermatologists, cosmetologists, biochemists, biologists, and those in the pharmaceutics industry, who need detailed and accurate information about the skin barrier on a daily basis. No R & D department should be without a copy.

Download or read book Skin Permeation and Disposition of Therapeutic and Cosmeceutical Compounds written by Kenji Sugibayashi and published by Springer. This book was released on 2017-11-28 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews skin permeation and disposition of chemical compounds. Skin is utilized as an administration site for transdermal drug delivery systems, topical drug formulations, cosmeceuticals, and cosmetics. Their usefulness is closely related to the permeation and disposition of entrapped active ingredients through and into the skin. Skin permeation, disposition, and metabolism of chemicals are first summarized in the general introduction. Then primary topical formulations are explained in the second part, “Basic Formulations Applied to Skin”. The explanation for the active compounds and formulations are of the most important parts required to fabricate these formulations. Skin absorption of chemicals is generally much lower than oral and the other mucosal absorptions, so that skin-penetration enhancement is a key issue to have good formulations topically applied. Part 3 presents “Skin Penetration Enhancement”. In addition, Part 4, “Selection of Topically Applied Chemical Candidates”, deals with selection methods of topically applied ingredients for transdermal drug delivery systems, topical drug formulations, cosmeceuticals, and cosmetics. Parts 5 and 6, “Safety Assessment of Topically Applied Compounds“ and “Experimental Methods of Skin Permeation“, respectively, show safety issues and experimental methods for topical formulations. The final part consists of comments on therapeutic and cosmetic formulations by medical doctors and pharmacists. Their comments are especially helpful for pharmaceutical and cosmetic researchers who study dermatopharmacokinetics and topical formulations. This volume is particularly useful for those working in R&D, graduate students, and educators in the area of pharmaceutics, cosmetic sciences, dermatological sciences, pharmacology, toxicology, biopharmacy, pharmacokinetics, physical pharmacy, chemical engineering, and related fields.
