Drug Absorption Studies In Situ In Vitro And In Silico Models

This is a well thought-out, highly practical text covering contemporary ‘in vitro’ techniques for drug absorption studies. Starting at the molecular level of investigation, it continues with cell monolayer models (both primary and cell lines) and culminates with in situ techniques as a final testing format. In addition, chapters on high-throughput assays, in vitro-in vivo correlation, bioinformatics and regulatory issues are covered, giving a comprehensive overview of available models and techniques. Moreover, an appendix consisting of a number of practical protocols is available online, updated as needed, and should prove very helpful to apply the techniques directly to the benchside.

This Book serves to highlight the mechanisms related to the low intestinal drug absorption, the strategies to overcome the obstacles or intestinal drug absorption, and in situ, in vitro, and in silico methodologies to predict to intestinal drug absorption. This Book presents a series of drug absorption studies and related technologies that predict intestinal permeation of drugs that govern the pharmacokinetic features of therapeutic drugs. It also contains the mechanistic understanding regarding the first-pass metabolism and intestinal efflux that modulate the pharmacokinetics of drug and suggest the formulation strategies to enhance the bioavailability of investigated drugs.

Pharmaceutical scientists in industry and academia will appreciate this single reference for its detailed experimental procedures for conducting biopharmaceutical studies. This well-illustrated guide allows them to establish, validate, and implement commonly used in situ and in vitro model systems. Chapters provide ready access to these methodologies for studies of the intestinal, buccal, nasal and respiratory, vaginal, ocular, and dermal epithelium as well as the endothelial and elimination barriers.

Oral Drug Absorption, Second Edition thoroughly examines the special equipment and methods used to test whether drugs are released adequately when administered orally. The contributors discuss methods for accurately establishing and validating in vitro/in vivo correlations for both MR and IR formulations, as well as alternative approaches for MR an

Concepts and Models for Drug Permeability Studies: Cell and Tissue Based in Vitro Culture Models, Second Edition, summarizes the most important developments in in vitro models for predicting the permeability of drugs. This book is structured around three different approaches, summarizing the most recent achievements regarding models comprising (i) immortalized cells with an intrinsic ability to grow as monolayers when seeded in permeable supports, (ii) primary cells isolated from living organisms and directly cultured as barrier monolayers, and (iii) tissue-based models constructed with cell lines and extracellular matrix that resembles the tridimensional structure of mucosae and other biological membranes, or animal/patient-derived tissues. Each model is covered in detail, including the protocol of generation and application for specific drugs/drug delivery systems. The equivalence between in vitro cell and tissue models and in vivo conditions is discussed, highlighting how each model may provisionally resemble different drug absorption route. Chapters included in the first edition were updated with relevant data published in recent years, while four new chapters were included to reflect new emerging directions and trends in drug permeability models. Concepts and Models for Drug Permeability Studies: Cell and Tissue Based in Vitro Culture Models, Second Edition, is a critical reference for drug discovery and drug formulation scientists interested in delivery systems intended for the administration of drugs through mucosal routes and other important tissue barriers (e.g. the BBB). Researchers studying mucosal biology can use this book to familiarize themselves and exploit the synergic effect of mucosal delivery systems and biomolecules. Summarizes the current advances in the use of permeability models in drug transport Covers the most important buccal, gastric, intestinal, pulmonary, nasal, vaginal, ocular, renal, skin, and blood–brain barrier in vitro models. Includes case studies to facilitate understanding of various concepts in computer-aided applications Updates in the second edition include organ-on-chip devices, 3D advanced models (multiple layered tissues, organoids, etc.), and multicompartmentalized tissue models

In an era wherein nanotechnology has sparked a huge research interest, brain drug delivery is not an exception. Aiming at fighting several central nervous system (CNS) conditions, tailored nanoparticles open new avenues to address several challenges in the fields of drug delivery and brain targeting. This book gathers contributions from experts in different, complementary fields, having in common their interest in developing new strategies for brain delivery based on nanotechnologies. The book encompasses general aspects pertaining to fundamental development, including tripartite in silico–in vitro–in vivo approaches. It also covers a diversity of nanomedicines applied in treatment and/or diagnosis and monitoring of CNS disorders. Aspects concerning their translation from the bench to clinical practice are also seamlessly discussed. This book will inspire readers to discover possible approaches to holistically delivering drugs into the brain. Edited by Carla Vitorino, Andreia Jorge and Alberto Pais, this book will appeal to anyone involved in nanomedicine, pharmaceutics, neurological and cancer therapies, drug delivery research and computational and regulatory sciences.
