Drug Delivery to the Brain: Physiological Concepts, Methodologies and Approaches (AAPS Advances in the Pharmaceutical Sciences Series, 33)

Introduction

"Drug Delivery to the Brain: Physiological Concepts, Methodologies and Approaches" is a seminal contribution to the ever-evolving field of neuropharmacology and drug delivery systems. Part of the prestigious AAPS Advances in the Pharmaceutical Sciences Series, Volume 33 of this series delves deep into the complexities of delivering therapeutic agents to one of the most challenging and poorly accessible organs in the body: the brain. The editors—Elizabeth C.M. de Lange, Margareta Hammarlund-Udenaes, and Robert G. Thorne—bring together decades of expertise to compile a comprehensive guide for researchers, clinicians, and pharmaceutical scientists who are striving to overcome the barriers imposed by the blood-brain barrier (BBB) and enhance therapeutic outcomes for central nervous system (CNS) disorders.

This book offers a multidisciplinary perspective, combining physiological concepts with advanced methodologies and novel approaches that are shaping the future of brain drug delivery. Covering a spectrum of topics ranging from the nuances of BBB permeability to cutting-edge nanoparticle systems and transport mechanisms, this volume ensures readers are well-equipped to tackle one of medicine’s greatest challenges—treating diseases of the brain effectively and safely. Whether you are a pharmaceutical scientist, neuroscientist, or medical professional, this book serves as an essential resource for broadening your understanding of brain-targeted drug delivery.

Detailed Summary of the Book

The book begins with a foundational overview of the physiological and anatomical barriers that hinder effective drug delivery to the brain, particularly the blood-brain barrier (BBB) and blood-cerebrospinal fluid barriers. Understanding these barriers provides the context necessary for subsequent discussions on how modern science is working to circumvent these constraints. The editors and contributors then explore a host of strategies, from exploiting transporter proteins and receptor-mediated endocytosis to physically disrupting the BBB under controlled conditions.

The next section of the book highlights methodologies and technologies that have emerged to enhance our ability to deliver drugs across the BBB. These include advanced imaging techniques, in vitro and in vivo models, and computational simulations. Insights into microdialysis, pharmacokinetic models, and biodistribution studies expand the reader’s grasp on the techniques used to measure drug delivery success in a clinical and preclinical setting.

Later chapters focus on the development of innovative therapeutic agents and delivery systems. Topics such as nanoparticle-based formulations, liposomes, and polymeric carriers are explored in-depth. Moreover, the book discusses the exciting potential of gene therapy, monoclonal antibodies, and other biologics in treating CNS disorders. Importantly, these sections bridge the gap between theoretical knowledge and its practical applications, ensuring that the material is both informative and actionable.

Finally, the book addresses the regulatory and translational challenges associated with brain drug delivery. It provides a candid outlook on the future of the field and the steps required to bring these advanced methodologies to the bedside. The ultimate goal is clear: to facilitate better treatments for neurological and psychiatric conditions while minimizing risks to patients.

Key Takeaways

• The blood-brain barrier remains a formidable challenge in delivering therapeutic agents to the CNS, but innovative approaches are breaking through this barrier.
