Download or read book Drug Delivery in Dermatology written by Célia Luiza Petersen Vitello Kalil and published by Springer Nature. This book was released on 2021-09-19 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Skin accounts for approximately 15% of an adult’s total body weight, with a surface of about 2m2. It provides an entry and exit barrier to various substances, offers effective protection against harmful substances, microorganisms and ultraviolet radiation, and is also paramount in immunology and body homeostasis, preventing dehydration and loss of essential minerals. The topical route has a number of advantages over oral and parenteral routes: no first-pass metabolism, greater convenience resulting in better treatment compliance, lower side-effect frequency, and prompt dosing cessation if required. However, the stratum corneum allows penetration of only 1 to 5% of substances applied topically, making this application route much less efficient. Lipophilic and small molecules (up to 500 Da) can cross the stratum corneum, since keratinocytes are covered by a lipid matrix, while it is virtually impossible for hydrophilic and large drugs to cross intact, normal skin, which means that passive topical delivery is restricted. To address this, techniques have been developed aimed at optimizing drug skin penetration by means of chemical, mechanical and physical methods, such as adding permeating active agents and using occlusion, iontophoresis, microneedling, lasers and intense pulsed light, and it is now possible to deliver medication to different skin layers or transdermally to the systemic circulation. Drug delivery is a hot topic in dermatology, with a Pubmed search generating 203431 articles. Offering a detailed review of this emerging therapeutic option, including the various methods available, this unique book guides physicians and doctors in selecting the correct technologies, technique and products for each patient.

Download or read book pH of the Skin Issues and Challenges written by C. Surber and published by Karger Medical and Scientific Publishers. This book was released on 2018-08-21 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of expressing acidity as the negative logarithm of the hydrogen ion concentration was defined and termed pH in the beginning of the 20th century. The general usefulness of the pH concept for life science was recognized and later gained importance to analytical research. Reports on results of pH measurements from living skin established the term acid mantle - the skin's own protective shield that maintains a naturally acid pH. It is invisible to the eye but crucial to the overall wellbeing of skin. Chronic alkalization can throw this acid mantle out of balance, leading to inflammation, dermatitis, and atopic skin diseases. It is therefore no surprise, that skin pH shifts have been observed in various skin pathologies. It is also obvious that the pH in topically applied preparations may play an important role. Optimal pH and buffer capacity within topical preparations not only support stability of active ingredients and auxiliary materials, but may also increase absorption of the non-ionized species of an acidic or a basic active ingredient. They may even open up opportunities to modify and "correct" skin pH and hence accelerate barrier recovery and maintain or enhance barrier integrity. Further efforts are needed to standardize and improve pH measurements in biological media or pharmaceutical/cosmetic vehicles to increase and ensure quality, comparability, and relevance of research data. In this volume, we present a unique collection of papers that address past, present and future issues of the pH of healthy and diseased skin. It is hoped that this collection will foster future efforts in clinical and experimental skin research.

Download or read book Dermal Drug Selection and Development written by Lionel Trottet and published by Springer. This book was released on 2017-08-07 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors show how the pharmaceutical industry faces the development of dermal drugs and provide the only book of its kind that describes how the industry develops and selects dermal drugs, complete with the challenges and opportunities of the field. Delivery of drugs through the skin has been an attractive and challenging area for research, and advances in modern technologies have resulted in a larger number of drugs being delivered transdermally, including conventional hydrophobic small molecule drugs, hydrophilic drugs and macromolecules. Offering the perspective from the industrial side of selection and development of drugs, the primary audience is geared towards the pharmaceutical industry but can also offer valuable information to clinicians, compounding pharmacists, and similarly pharmacy students. Dermal Drug Selection and Development covers the scientific gaps that exist in terms of dermal pharmacokinetics and the resulting uncertainty by clinicians when choosing a drug candidate.

Available in PDF, EPUB and Kindle. Book excerpt: Nanoscience in Dermatology covers one of the two fastest growing areas within dermatological science, nanoscience and nanotechnology in dermatology. Recently, great progress has been made in the research and development of nanotechnologies and nanomaterials related to various applications in medicine and, in general, the life sciences. There is increasing enthusiasm for nanotechnology applications in dermatology (drug delivery, diagnostics, therapeutics, imaging, sensors, etc.) for understanding skin biology, improving early detection and treatment of skin diseases, and in the design and optimization of cosmetics. Light sensitive nanoparticles have recently been explored, opening a new era for the combined applications of light with nanotechnology, also called photonanodermatology. However, concerns have been raised regarding the adverse effects of intentional and unintentional nanoparticle exposure and their toxicity. Written by experts working in these exciting fields, this book extensively covers nanotechnology applications, together with the fundamentals and toxicity aspects. It not only addresses current applications of nanotechnology, but also discusses future trends of these ever-growing and rapidly changing fields, providing scientists and dermatologists with a clear understanding of the advantages and challenges of nanotechnology in skin medicine.
