The Actions and Uses of Ophthalmic Drugs by P. H. O'Connor Davies,G. A. Hopkins,R. M. Pearson Pdf

The Actions and Uses of Ophthalmic Drugs, Third Edition discuses the application and discrimination in the use of ophthalmic drugs. The book reviews the general pharmacological principles including drug nomenclature, pharmacological classification, pharmacokinetics, pharmacodynamics, and the use of these drugs. Ophthalmic drugs (cycloplegics, mydriatics, miotics) directly or indirectly, stimulate or inhibit a part of the autonomic nervous system connected to the intra-ocular muscles. The text investigates in detail the structure and function of this involuntary nervous system in the orbital region as it is affected by these drugs. The book explains the different drug classifications, their therapeutic and diagnostic purposes, including the ideal properties, indications, contra-indications, mode of action, or adverse effects of cycloplegics, of mydriatics, and of miotics. The book also describes the uses and characteristics of local anesthetics, stains, anti-infective agents, and miscellaneous agents (antihistamines, vasoconstrictors). The text explains the different types of contact lens solutions, application of ocular first aid, as well as, the possible adverse ocular reactions that can occur during ophthalmic drug therapy. This book is suitable for optometrists, pharmacists, pharmacologists, students and professors related to the discipline of optometry and general medicine.

The Actions and Uses of Ophthalmic Drugs by P. H. O'Connor Davies Pdf

The Actions and Uses of Ophthalmic Drugs: A Textbook for Students and Practitioners, Second Edition provides pertinent information in relation to concepts in pharmacology, the formulation and application of ophthalmic drugs, and adverse ocular effects of systemic medication. This book discusses the preparations used in contact lens practice. Organized into 17 chapters, this edition begins with an overview of the primary systems of drug classification according to their actions or effects, or on the basis of their chemistry. This text then presents a detailed discussion on the actions and uses of ophthalmic autonomic drugs. Other chapters consider the structure and function of the involuntary nervous system in the orbital region. This book discusses as well the two main classifications of ophthalmic drugs, namely, therapeutic and diagnostic. The final chapter deals with the clinical significance of medication-induced ocular adverse effects. This book is a valuable resource for ophthalmologists, students, and practitioners.

Handbook of Basic and Clinical Ocular Pharmacology and Therapeutics by Sunny Ohia,Najam Sharif Pdf

Handbook of Basic and Clinical Ocular Pharmacology and Therapeutics provides a review of the basic anatomy, physiology, biochemistry and pathology of the eye with a focus drug therapy, drug delivery and use of therapeutic medical miniature devices. An understanding of the pharmacological actions of drugs acting on the eye requires the student and health care practitioner to learn additional principles in basic and clinical sciences that are unique to this organ. As a sensory organ, the eye is relatively inaccessible to the systemic circulation due to the blood-vitreous, blood-aqueous and blood-retinal barriers. Consequently, the administration of drugs for therapeutic effects in the eye necessitates an understanding of physico-chemical properties of the molecules and pharmacokinetic principles involved in the access to its site of action via topical, intracameral and intravitreal administration. This book includes information on the general principles of pharmacokinetics and pharmacodynamics of drugs as it pertains to the eye and in combating ocular disorders and diseases. Using a disease-themed approach, the book discusses basic and clinical pharmacological principles involved in the therapy of these diseases including the ocular side effect of systemically-administered drugs, drugs used in ophthalmic surgery and miscellaneous agents, the therapeutic utility of biologics, drug conjugates, combination products, gene and cellular therapy are also covered. Handbook of Basic and Clinical Ocular Pharmacology and Therapeutics is useful as a primary and secondary source of reference for up-to-date information about the pharmacological mechanisms of action, pharmacokinetics, side effects, drug-drug interactions and therapeutic indications of drugs for pharmacologists, pharmaceutical scientists, students in the health care disciplines (nursing, pharmacy, optometry, medical), and practitioners in optometry and ophthalmology. Explains the mechanisms of action, side-effects and therapeutic uses of drugs, biologics, miniature devices, gene and cellular therapies for the eye Provides a comprehensive review of the anatomy, physiology, biochemistry, pharmacology, microbiology, genetics and pathology of parts of the eye involved in drug therapy to combat eye disorders and diseases Explores the pharmacological and clinical basis of drugs, drug conjugates, combination products used in the treatment of anterior and posterior segment diseases

Update on Polymers for Ocular Drug Delivery by Atish S Mundada Pdf

The eye is the most easily accessible site for topical administration of a medication. Drugs are commonly applied to the eye for localised action on the surface or in the interior of the eye. A major problem in ocular therapeutics is the attainment of an optimal drug concentration at the site of action. Poor bioavailability of drugs from ocular dosage forms is mainly due to the precorneal loss factors which include tear dynamics, non-productive absorption, transient residence time in the cul-de-sac, and the relative impermeability of the corneal epithelial membrane. Due to these physiological and anatomical constraints only a small fraction of the drug, effectively 1% or even less of the instilled dose is ocularly absorbed. The effective dose of medication administered ophthalmically may be altered by increasing the retention time of medication in contact with the surface of the eye. To date, Pharmaceutical Technologists have tried to develop different novel formulations like gel, ocular inserts, collagen shields, implants, liposomes, nanoparticles, penetration enhancers and in-situ gelling systems, in order to increase the bioavailability and duration of the therapeutic action of ocular drugs and polymers plays an important role in all these approaches. This book provides detailed information regarding all such polymers which have been used and shown to be excellent in improving the bioavailability of ocular drugs.
