Drug discovery for ocular diseases has taken great strides in the last two decades. From cornea to choroid, new drugs have been formulated to address a great variety of ocular diseases. Yet without good drug delivery systems, these drugs are less effective than they might be or could even cause serious side effects. Ocular Drug Delivery Systems: Barriers and Application of Nanoparticulate Systems presents research on the development of currently marketed devices and recent trends in the topical delivery of drugs to the posterior of the eye. With contributions from leading pharmaceutical researchers and industry experts, eye researchers, surgeons, pharmacologists from academia, the National Eye Institute, and leading ophthalmic companies such as Pfizer, Allergan, and Novartis, the book presents the state of the art in the use of nanoparticles in ocular drug delivery systems and also sets the stage for future developments. This volume provides both a current evaluation and a future roadmap for developments in ocular drug delivery. The subjects range from biological needs to material challenges and finally to clinical applications for improving drug delivery for conditions where treatments already exist. It also explores areas where effective drugs may be currently available but yet need a safe, efficient, and efficacious delivery vehicle.

Provides comprehensive coverage of microneedles for delivering and monitoring patient drugs and vaccines Microneedles are an incredibly active research area and have the potential to revolutionize the way many medicines and vaccines are delivered. This comprehensive research book covers the major aspects relating to the use of microneedle arrays in enhancing both transdermal and intradermal drug delivery and provides a sound background to the use of microneedle arrays in enhanced delivery applications. Beginning with a history of the field and the various methods employed to produce microneedles from different materials, Microneedles for Drug and Vaccine Delivery and Patient Monitoring discusses the penetration of the stratum corneum by microneedles and the importance of application method and force and microneedle geometry (height, shape, inter-needle spacing). Transdermal and intradermal delivery research using microneedles is comprehensively and critically reviewed, focusing on the outcomes of in vivo animal and human studies. The book describes the important topics of safety and patient acceptability studies carried out to date. It also covers in detail the growing area for microneedle use in the monitoring of interstitial fluid contents. Finally, it reviews translational and regulatory developments in the microneedles field and describes the work ongoing in industry. The only book currently available on microneedles Filled with tables, graphs, and black and white images (photographs, micrographs) Authored by four experts in pharmaceutics Microneedles for Drug and Vaccine Delivery and Patient Monitoring is an ideal source for researchers in industry and academia working on drug delivery and transdermal delivery in particular, as well as for advanced students in pharmacy and pharmaceutical sciences.

Academic Paper from the year 2023 in the subject Medicine - Pharmacology, Pharmacy, , course: M.Pharmacy, language: English, abstract: Ocular drug delivery plays a vital role in the treatment of various eye diseases and conditions. The unique anatomical and physiological characteristics of the eye pose significant challenges for effective drug delivery. Over the years, extensive research efforts have been dedicated to developing innovative strategies and formulations to overcome these challenges and improve therapeutic outcomes. This review provides an overview of recent advances in ocular drug delivery, highlighting the key challenges faced and discussing the potential future directions in this field. The first section of the review focuses on the barriers to ocular drug delivery, including the tear film, cornea, conjunctiva, and blood-ocular barriers. These barriers limit the bioavailability and efficacy of drugs administered to the eye. Strategies to bypass or overcome these barriers, such as the use of penetration enhancers, nanoparticles, and prodrug approaches, are discussed. The second section explores various ocular drug delivery systems, including eye drops, ophthalmic gels, ocular inserts, and contact lens-based delivery systems. Each system is examined in terms of its advantages, limitations, and recent advancements. Special attention is given to sustained drug release systems that aim to prolong drug residence time on the ocular surface and improve patient compliance. Next, the review delves into the role of nanotechnology in ocular drug delivery. Nanoparticles, liposomes, and nanomicelles have shown promise in improving drug solubility, stability, and ocular bioavailability. The use of novel nanomaterials and their surface modifications for targeted drug delivery to specific ocular tissues is also discussed. Furthermore, the review highlights emerging techniques in ocular drug delivery, such as microneedles, hydrogels, and gene therapy-based approaches. These technologies offer exciting prospects for precise and personalized treatment of ocular diseases. Finally, the review concludes by discussing the regulatory considerations, safety aspects, and clinical translation of ocular drug delivery systems. The importance of collaboration between researchers, clinicians, and regulatory bodies in advancing this field is emphasized.

This book addresses the issues relating to a wide variety of ocular diseases from which millions of people suffer. Long-term challenges include visual impairment and ocular blindness. Certain ocular diseases are quite rare, whereas others, such as cataracts, age-related macular degeneration (AMD), and glaucoma, are very common, especially in the aging population. A rapid expansion of new technologies in ocular drug delivery and new drug candidates, including biologics, to treat these challenging diseases in the retina and posterior segments of the eye have recently emerged. These approaches are necessary because the eye has many unique barriers to drug delivery. Thus, this timely reference Drug Delivery for the Retina and Posterior Segment Disease compiles and analyzes recent advances in the research and development of drug delivery systems for retina and posterior segment diseases of the eye, with an emphasis on the use of implantable devices, iontophoresis as well as micro- and nanoparticles.
