Book Description
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.

Book Description
Conventional ophthalmic formulations lack prolonged drug release effects and mucoadhesive properties, decreasing their residence time in the precorneal area and, therefore, in drug penetration across ocular tissues, presenting a low bioavailability with a consequent reduction in the therapeutic efficacy. These limitations are related to the physiological mechanisms of the eye, for example, the diluting effect of formulations exerted by the tear fluid, constant turnover of the tear fluid, blink reflex, limited capacity of the conjunctival sac, and drainage of formulations applied by gravity. To increase the residence time of formulations on the surface of ocular tissues and increase their ability to penetrate these tissues, different strategies can be used, namely, the use of viscosifying agents, mucoadhesive polymers, stimuli-responsive polymers, microparticles, and colloidal carriers (e.g., micelles, liposomes, nanosuspensions, nanoemulsions, polymeric, and lipid nanoparticles). This Special Issue combines the latest research and review works reporting the use of nanoparticles in ophthalmic formulations to increase their bioavailability and improve the therapeutic efficacy of ophthalmic formulations.

Book Description
This consolidated reference book addresses the various aspects of nano biomaterials used in ophthalmic drug delivery, including their characterization, interactions with ophthalmic system and applications in treatments of the ophthalmic diseases and disorders. In the last decade, a significant growth in polymer sciences, nanotechnology and biotechnology has resulted in the development of new nano- and bioengineered nano-bio-materials. These are extensively explored as drug delivery carriers as well as for implantable devices and scaffolds. At the interface between nanomaterials and biological systems, the organic and synthetic worlds merge into a new science concerned with the safe use of nanotechnology and nano material design for biological applications. For this field to evolve, there is a need to understand the dynamic forces and molecular components that shape these interactions. While it is impossible to describe with certainty all the bio physicochemical interactions at play at the interface, we are at a point where the pockets of assembled knowledge are providing a conceptual framework to guide this exploration, and review the impact on future product development. The book is intended as a valuable resource for academics and pharmaceutical scientists working in the field of polymers, polymers materials for drug delivery, drug delivery systems and ophthalmic drug delivery systems, in addition to medical and health care professionals in these areas.

Book Description
A multidisciplinary approach is increasingly being adapted by the Pharmaceutical industry to tackle several challenges in developing efficacious treatment solutions. The field of Ophthalmology is no less different. Treatise on Ocular Drug Delivery is a unique collection of information put together by various experts in the field. One of the major goals behind this volume is to link clinical information with the current strategies employed in ocular drug delivery. This monograph covers a range of topics on ocular pharmacology. Chapters in the e-book cover several aspects of drug delivery research such as the biochemical background of specific eye diseases, challenges for ocular drug delivery, the role of influx and efflux transporters, novel drug delivery systems, pharmacokinetics, regulatory aspects, and patenting opportunities for researchers. This E-Book would serve as a suitable reference for pharmacy graduates, medical students, professional scientists and ophthalmic clinicians in academic and industrial laboratories.

Book Description
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.
