With the continued advancement of better-quality control and patient outcome reporting systems, changes in the development, control, and regulation of all pharmaceutical delivery systems including transdermal and topical products have been happening on a continuous basis. In light of various quality issues that have been reported by patients and practitioners resulting in the recall or removal of products from the market, both the pharmaceutical industries and regulatory agencies have been adopting new measures to address these issues. With chapters written by experts in this field, this book takes a 21st century multidisciplinary and cross-functional look at these dosage forms to improve the development, design, manufacturing, quality, clinical performance, safety, and regulation of these products. This book offers a wealth of up-to-date information organized in a logical sequence corresponding to various stages of research, development, and commercialization of dermal drug delivery products. The authors have been carefully selected from different sectors of pharmaceutical science for their expertise in their selected areas to present objectively a balanced view of the current state of these products development and commercialization via regulatory approval. Their insights will provide useful information to others to ensure the successful development of the next generation dermal drug products. Key Features: Presents current advancements including new technologies of transdermal and topical dosage forms. Presents challenges in the development of the new generation of transdermal and topical dosage forms. Introduces new technologies and QbD (quality by design) aspects of manufacturing and control strategies. Includes new perspectives on pre-clinical and clinical development, regulatory considerations, safety and quality. Discusses regulatory challenges, gaps, and future considerations for dermal drug delivery systems.

This work represents an inventive attempt to apply recent advances in nanotechnology to identify and characterise novel polymer systems for drug delivery through the skin. Atomic force microscopy (AFM) measurements of the nanoscale mechanical properties of topical, drug-containing polymeric films enabled the author to identify optimal compositions, in terms of flexibility and substantivity, for application to the skin. To elucidate the enhanced drug release from polyacrylate films incorporating medium chain triglycerides, the author combined AFM studies with the complementary technique of Raman micro-spectroscopy. This experimental strategy revealed that the significant increase in the drug released from these films is the result of a nanoscale two-phase structure. Finally, in experiments examining the microporation of skin using femtosecond laser ablation, the author demonstrated that the threshold at which the skin's barrier function is undermined can be dramatically reduced by the pre-application of ink. The approach allows thermal damage at the pore edge to be minimised, suggesting a very real potential for substantially increasing drug delivery in a minimally invasive fashion.

This book presents new approaches for skin aging and photocarcinogenesis and topical formulations based on nanocarrier systems for skin disorders. It discusses cosmeceuticals, laser, photodynamic therapy, and melatonin-based treatments as important strategies for photoaging management. Photodynamic therapy and melatonin can be used in the photocarcinogenesis context, too. Therefore, the inclusion of this strong antioxidant in sunscreen products could be a promising approach. The book discusses topical formulations, including emulsions (conventional formulations and emulsions stabilized by solid particles), nail films, and nanocarriers used for the delivery of actives in various skin and nail diseases such as acne, psoriasis, atopic dermatitis, fungal diseases, leishmaniasis, and skin cancer. Finally, several nanocarriers are introduced, such as lipid vesicles (ranging from the first-generation conventional liposomes to the more recent deformable vesicles), liquid crystalline nanodispersions, gelatin, and solid lipid nanoparticles. Their composition, formulation, characterization, and topical applications are also discussed. Although this is a broad topic, the most important (nano)pharmaceutical formulations are presented in the book.

This volume addresses efforts to overcome the shortcomings of conventional dosage forms by exploiting the principles of nanoscience to deliver drugs for medical treatment. Nanodispersions are an important aspect because they possess globules/particles in sizes usually below 1000 nm in which the drug is dispersed in a continuous medium employing surface-active agents as stabilizers. With chapters written by experienced scientists and researchers in the field, this volume provides an abundance of information on various aspects of nanodispersions for drug delivery. The book is divided into several sections: nanoemulsions, nanosuspensions, and diverse dispersed systems. The chapters detail what nanodispersions have demonstrated in the past and what they are expoected to continue to do in the future as the technology further evolves. Key features: • Provides an overview of nanoemulsions for drug delivery • Introduces the general principles, classification, and methods of preparation of nanoemulsion-based drug delivery systems • Presents information relevant to specific routes of applications of nanoemulsions • Looks at the various aspects of nanosuspensions, including their formulation components, preparation methods, unique features, methods of characterization, and applications in various routes of administration • Explores nanomicellar approaches for drug delivery • Discusses the preparation, applications, and clinical considerations of nanogels for drug delivery
