Introduction. Biopharmaceutics and Pharmacokinetics
No full textBiopharmaceutics and pharmacokinetics are pharmaceutical disciplines useful to improve the outcome of drug therapies, assist drug product development, and establish pharmacokinetics-pharmacodynamics models and in vitro-in vivo correlations. Here, we introduce some essential lexicon that will be used throughout this volume and discuss the relationship between drug exposure and pharmacological response, in the framework of the free drug theory/hypothesis.Fil: Talevi, Alan.

Drug Transporters
No full textMembrane transporters perform a central function in protecting the body from xenobiotics (either by preventing their absorption, limiting their distribution or promoting their elimination). Transporters can also take part in the traffic and compartmentalization of endogenous compounds. In some particular cases, they may favor drug absorption and/or distribution. Accordingly, they are of major importance from a pharmacological perspective. Transporter protein science is an emerging field, and their identification and characterization continue to evolve, with their medical and pharmaceutical impact being still far from being fully understood. In relation to drug kinetics, two gene families coding for polyspecific transporters are of particular importance: the ATP-binding cassette (ABC) transporters and the solute carrier (SLC) transporters. Both will be discussed in this last chapter of this volume.Fil: Talevi, Alan. Universidad Nacional de La Plata. Facultad de Ciencas Exactas.

Drug Excretion
No full textAbsorption, Distribution, Metabolism and Excretion (ADME) processes and their relationship with the design of dosage forms and the success of pharmacotherapy form the basis of this upper level undergraduate/graduate textbook. As an introduction oriented to pharmacy students, it is also written for scientist from different fields outside of pharmaceutics. (e.g. material scientist, material engineers, medicinal chemists) who might be working in a positions in pharmaceutical companies or whose work might benefit from basic training in the ADME concepts and some biological background. Pedagogical features such as objectives, keywords, discussion questions, summaries and case studies add valuable teaching tools. This book will provide not only general knowledge on ADME processes but also an updated insight on some hot topics such as drug transporters, multi-drug resistance related to pharmacokinetic phenomena, last generation pharmaceutical carriers (nanopharmaceuticals), in vitro and in vivo bioequivalence studies, biopharmaceuticals, pharmacogenomics, drug-drug and food-drug interactions, and in silico and in vitro prediction of ADME properties. In comparison with other similar textbooks, around half of the volume would be focused on the relationship between expanding scientific fields and ADME processes. Each of these burgeoning fields has a separate chapter in the second part of the volume, and was written with leading experts on the correspondent topic, including scientists and academics from USA and UK (Duquesne University School of Pharmacy, Indiana University School of Medicine, University of Utah College of Pharmacy, University of Maryland, University of Bath).Additionally, each of the initial chapters dealing with the generalities of drug absorption, distribution, metabolism and excretion would include relevant, classic examples related to each topic with appropriate illustrations (e.g. importance of active absorption of levodopa, implications in levodopa administration, drug drug interactions and food drug interactions emerging from the active uptake; intoxication with paracetamol as a result of glutathione depletion, CYP induction and its relationship with acute liver failure caused by paracetamol, etc).ADME Processes and Pharmaceutical Sciences is written as a core textbook for ADME processes, pharmacy, pharmacokinetics, drug delivery, biopharmaceutics, drug disposition, drug design and medicinal chemistry courses.Fil: Talevi, Alan.

Urban Rests and Green - Between
No full textThis proposal aims to contribute to the exploration of the role of architectural and urban projects by
proposing actions to improve the health and well-being of the life of city dwellers and the health of
the cities themselves. Through an fragment of the city of Naples – the former Provincial Asylum "Leonardo
Bianchi" – some principles and criteria are referred to and drawn upon in order to direct urban transformations towards more health-friendly approaches. Within contemporary cities, the linking up of residual green spaces represents an opportunity to take care of the city and consequently something to be taken care of by the city in a truly sustainable development
Drug repositioning: current approaches and their implications in the precision medicine era
No full textIntroduction: Drug repositioning implies finding new medical uses for existing drugs. It represents a cost-efficient approach, since the new indications are built on the basis of available information on pharmacokinetics, safety and manufacturing. Whereas most of the pioneering drug repurposing stories arose from serendipitous observations and clever exploitation of side effects, the drug discovery community has lately addressed repurposing initiatives in a more systematic manner. Today, in the middle of the omics era, we have the tools to explore drug repurposing opportunities in a tailored, personalized manner. Areas covered: After a brief discussion on modern approaches to drug repurposing, the author connects the philosophies of drug repurposing and personalized medicine through the well-known and extended practice of off-label prescription. The author also discusses which, among current systematic repurposing approaches, are more appropriate to be integrated with the field of precision medicine. Expert commentary: Personalized drug repurposing is not a new concept at all: for years, it has been known as off-label prescription, a practice widely accepted especially in some branches of medicine. Whereas in the past such approach was in many cases supported by empiric knowledge, today omics technologies allow us to face novel personalized drug repurposing options in a systematic manner.Fil: Talevi, Alan.
