Background and objective: Ocular drug delivery research is challenging due to the presence of anatomical and physiological barriers. The ophthalmic preparation of diclofenac sodium DC for relieving ocular inflammation is presently available in the market only as an eye drop solution with low ocular bioavailability. Methods : Formulation was developed and optimized for three different variables chondroitin sulfate, chitosan, and initial drug concentration. The developed formula was evaluated by various in-vitro parameters such as particles' size, entrapment efficacy, zeta potential, and in vitro release profile. Results : The particles' size, entrapment efficacy, and zeta potential of the best formulation were found to be

Review on Basic Concept for Ophthalmic Preparations

This book provides a list of concise extemporaneous ophthalmic preparations, and standardizes the formulation of the products by suggesting specific strength, route of administration, appropriate vehicle, and method of preparation. Pharmaceutical industries have greatly expanded their share of ophthalmic drugs in recent years. However, physicians and pharmacists are frequently called to prepare sterile products intended for ophthalmic use due to lack of availability of licensed drugs in the market.

The present work describes the formulation and evaluation of an ophthalmic delivery system of an antibacterial agent, ciprofloxacin, which is used in the treatment of eye infection such as dacrocystitis, bacterial conjunctivitis, corneal ulceration and blepharitis, based on the concepts of ph-triggered in-situ gelation, thermo reversible gelation and Ion activated system. Poly acrylic acid Carbopol was used as the gelling agent in combination of hydroxy propyl methylcellulose, which acted as a viscosity-enhancing agent. Gellan gum Gelrite is an anionic exocellular polysaccharide by the bacterium pseudo Monas elodea, having the characteristic property cation-induced gelation 0. The developed system is thus a viable alternative to conventional eye drops.

The orally administered acetazolamide has a limited use in glaucoma due to the systemic side effects associated with its use. In order to enhance the bioavailability of the drug, contact time between the drug molecules and the ocular surface was increased using high viscosity, water soluble polymers PVA, HPMC , and by incorporating acetazolamide into an in situ-forming ophthalmic drug delivery system. Moreover, a penetration enhancer EDTA was also used in these formulations to increase the extent of absorption of the drug. The effect of these formulations on the IOP in normotensive conscious rabbits was also investigated. These formulations were found to be therapeutically effective with a peak effect at 2 h. A fall in IOP of up to


11, From the above description, the researcher was interested in making hydrogel preparation formulation as an ophthalmic drug delivery system that has good.


Ocular drug delivery has been a major challenge to pharmacologists and drug delivery scientists due to its unique anatomy and physiology. Ophthalmic preparations are sterile liquid, semi-solid, or solid preparations intended for application to the conjunctiva, the conjunctival sac, or the eyelids. Sterility is very important factor in manufacture and use of ophthalmic products. Preservative selection is also an important activity in product design.

Objective: This work aims to formulate and evaluate an ophthalmic in-situ gel of ciprofloxacin hydrochloride HCl using poloxamer P as a gelling agent and hydroxypropyl methylcellulose HPMC as a viscosity modifier. The objective of this work was to prolong the contact time as the in-situ gel will be converted into a gel upon contact with the cul-de-sac. Methods: Ciprofloxacin HCl ophthalmic in-situ gel was prepared by utilizing P as a temperature-dependent polymer while hydroxypropyl methylcellulose was used as a viscosity modifier. The system was evaluated for physical appearance, pH, drug content, sterility, irritancy and stability.

 Черт возьми! - выругался Бринкерхофф.  - В обеих бомбах уран. Элементы, ответственные за Хиросиму и Нагасаки, - оба являются ураном. Никакого различия.

Все люди на подиуме потянулись к терминалу в одно и то же мгновение, образовав единое сплетение вытянутых рук. Но Сьюзан, опередив всех, прикоснулась к клавиатуре и нажала цифру 3.

За полтора метра до стеклянной двери Сьюзан отпрянула в сторону и зажмурилась. Раздался страшный треск, и стеклянная панель обдала ее дождем осколков. Звуки шифровалки впервые за всю историю этого здания ворвались в помещение Третьего узла.

 Пошел к черту. - У меня неотложное дело! - рявкнул Беккер. Он схватил парня за рукав.

Фонтейн кивнул. Иерархия допуска в банк данных была тщательно регламентирована; лица с допуском могли войти через Интернет. В зависимости от уровня допуска они попадали в те отсеки банка данных, которые соответствовали сфере их деятельности. - Поскольку мы связаны с Интернетом, - объяснял Джабба, - хакеры, иностранные правительства и акулы Фонда электронных границ кружат вокруг банка данных двадцать четыре часа в сутки, пытаясь проникнуть внутрь. - Да, - сказал Фонтейн, - и двадцать четыре часа в сутки наши фильтры безопасности их туда не пускают.

 У него было больное сердце, - сказал Фонтейн.

Никому не показалось удивительным, что два дня спустя АНБ приняло Грега Хейла на работу. Стратмор решил, что лучше взять его к себе и заставить трудиться на благо АНБ, чем позволить противодействовать агентству извне. Стратмор мужественно перенес разразившийся скандал, горячо защищая свои действия перед конгрессом. Он утверждал, что стремление граждан к неприкосновенности частной переписки обернется для Америки большими неприятностями. Он доказывал, что кто-то должен присматривать за обществом, что взлом шифров агентством - вынужденная необходимость, залог мира.

Стратмор оторвался от перил и переложил пистолет в правую руку. Не произнеся ни слова, он шагнул в темноту, Сьюзан изо всех сил держалась за его плечо. Если она потеряет с ним контакт, ей придется его позвать, и тогда Хейл может их услышать. Удаляясь от таких надежных ступенек, Сьюзан вспомнила, как в детстве играла в салки поздно ночью, и почувствовала себя одинокой и беззащитной, ТРАНСТЕКСТ был единственным островом в открытом черном море. Через каждые несколько шагов Стратмор останавливался, держа пистолет наготове, и прислушивался.

Бринкерхофф с облегчением вздохнул: - Ну, если он здесь, то нет проблем, верно. Мидж задумалась. - Может. - Может .

Preparation and Evaluation of In-Situ-Gels for Ocular Drug Delivery

Голос Фонтейна по-прежнему звучал спокойно, деловито: - Можете ли вы его остановить.
