Drug Delivery to the Central Nervous System by Kewal K. Jain Pdf

Playing an important role in the treatment of neurological disorders, the delivery of drugs to central nervous system (CNS), both administered directly and administered systematically for targeted action, encounters a major challenge in the form of the blood-brain barrier (BBB), which limits the access of drugs to the brain substance. In Drug Delivery to the Central Nervous System, experts in the field present essential methods used to deliver therapeutics across the BBB, both in experimental animals and in humans. In addition to those methods, several overviews of innovative methods and their applications are presented in order to give a glimpse of the future of this research. As a volume in the successful Neuromethods series, this book presents its protocols with the kind of detailed description and implementation advice that is crucial for getting optimal results. Authoritative and cutting-edge, Drug Delivery to the Central Nervous System serves as an ideal guide to scientists continuing to pursue knowledge of the delicate interactions between pharmaceuticals and the brain.

Drug Delivery to the Brain by Margareta Hammarlund-Udenaes,Elizabeth C.M. de Lange,Robert G. Thorne Pdf

The development of new CNS drugs is notoriously difficult. Drugs must reach CNS target sites for action and these sites are protected by a number of barriers, the most important being the blood –brain barrier (BBB). Many factors are therefore critical to consider for CNS drug delivery, e.g. active/passive transport across the BBB, intra-brain distribution, and central/systemic pharmacokinetics, to name a few. Neurological disease and trauma conditions add further complexity because CNS barriers, drug distribution and pharmacokinetics are dynamic and often changed by disease/trauma. Knowledge of all these factors and their interplay in different conditions is of utmost importance for proper CNS drug development and disease treatment. In recent years much information has become available for a better understanding of the many factors important for CNS drug delivery and how they interact to affect drug action. This book describes small and large drug delivery to the brain with an emphasis on the physiology of the BBB and the principles and concepts for drug delivery across the BBB and distribution within the brain. It contains methods descriptions for studying drug delivery, routes and approaches of administering drugs into the brain, the influence of disease, and drug industry perspectives. Therewith, it contributes to an in-depth understanding of the interplay between brain (patho)-physiology and drug characteristics. Furthermore, the content is designed to be both cutting-edge and educational, so that the book can be used in high-level training of academic and industry scientists with full references to original publications. ​

Enabling Novel Treatments for Nervous System Disorders by Improving Methods for Traversing the Bloodâ¬"Brain Barrier by National Academies of Sciences, Engineering, and Medicine,Health and Medicine Division,Board on Health Sciences Policy,Forum on Neuroscience and Nervous System Disorders Pdf

Despite substantial advances in developing treatments for the serious illnesses that affect people worldwide, there remains a tremendous unmet need in the treatment of complex neurologic diseases, including neuropsychiatric and neurodegenerative disorders. Chief among the challenges that have hindered the development of therapeutics for central nervous system (CNS) disorders is the bloodâ€"brain barrier (BBB). The Forum on Neuroscience and Nervous System Disorders of the National Academies of Sciences, Engineering, and Medicine convened a workshop to explore the challenges associated with the BBB that have thus far stymied development of CNS drugs, examine new technologies that could address these challenges, and highlight potential opportunities for moving the field forward. This publication summarizes the presentations and discussions from the workshop.

Blood-Brain Barrier by David Kobiler,Shlomo Lustig,Shlomo Shapira Pdf

The vasculature of the central nervous system (eNS) is characterized by the existence of the blood-brain barrier (BBB), which can be regarded as both an anatomical and physiological phenomenon. The BBB is formed by a complex cellular system of endothelial cells, astroglia, pericytes, perivascular macrophages and a basal membrane, although the anatomic substrate of the BBB is the interendothelial tight junctions that form a continuous sealing. The BBB serves as an exquisitely controlled, functional gate to the eNS. It not only protects the brain from agents in the blood that could impair neurological function, but also controls the influx and efflux of numerous substances to maintain proper homeostasis and provide the brain with necessary nutrients. The structural and functional integrity of the BBB was shown to be dramatically altered during various diseases of the eNS, including neoplasia, ischemia, trauma, hypertension, inflammation and epilepsy. Recent years research has partially elucidated the mechanisms underlying the development of some of these brain disorders as well as the pathways used by different pathogens, like bacteria and viruses, to initiate eNS infections. The development of in vitro models of the BBB had instrumental role in the understanding of the involvement of the BBB in the pathogenesis of several eNS diseases. The intimate, functional association between the function of the brain and the activity of the BBB makes the later a target for pharmacological modulation that will expand the therapeutic possibilities for a range of neurological diseases.

Therapeutic Intranasal Delivery for Stroke and Neurological Disorders by Jun Chen,Jian Wang,Ling Wei,John H. Zhang Pdf

The blood-brain-barrier serves to encapsulate and protect the central nervous system, but it also presents a major barricade to therapeutic drug delivery. Poor penetration is the most common hurdle to translating a promising experimental therapy that uses invasive delivery methods to a clinically useful application. In the last 10 years, intranasal delivery of various therapeutic compounds including small chemicals, large proteins, and even stem cells has proven to be very effective in bypassing the blood-brain-barrier and has led to some important advances in translational research for stroke and other neurological diseases. The proposed book will bring together reports from various labs around the world who have had successes in pre-clinical studies of intranasal therapies for various diseases including adult and perinatal stroke, Alzheimer's, Parkinson's, and others.​

Peptide Transport and Delivery into the Central Nervous System by Laszlo Prokai,Katalin Prokai-Tatrai Pdf

Hypo- or hypersecretion, alteration in storage, release, catabolism, and post-translational processing of neuropeptides are associated with the etiology of many diseases affecting the central nervous system (CNS). Various peptides native to the brain and the spinal cord, as well as various synthetic peptides, peptide analogues and peptidomimetics developed as their agonists or antagonists could be useful in the treatment of these CNS maladies. However, peptides face a formidable obstacle in reaching the intended site of action due to the existence of the blood-brain barrier (BBB), a vital element in the regulation of the internal environment of the brain and the spinal cord. After reviews on the role and neuropharmaceutical potential of peptides, properties of the BBB in the context of peptide transport in the CNS and potential transport mechanisms to cross the BBB, this volume discusses the development, present state-of-the-art and future trends of various strategies to overcome this major obstacle to peptide pharmacotherapy involving the CNS. Chapters are devoted to cover invasive approaches that circumvent the BBB by direct administration into the brain or the spinal cord and by transiently opening the tight junctions of or permeabilizing the endothelial cells separating the systemic circulation from the interstitial fluid of the CNS. Subsequently, physiologically based strategies that utilize biological carriers to gain access to the CNS are discussed in detail, followed by methods encompassing prodrug and chemical delivery/targeting strategies, which aim at altering the properties of the peptide to enhance BBB transport, and drug delivery strategies based on peptide vectors. Finally, a comparative evaluation on the present status and perspectives of the techniques is presented.
