Pharmacy College, Paloncha - , Telangana, India. ABSTRACT: The objective of the present study is to develop a pharmaceutically stable sustained release matrix tablets of Baclofen and perform the pre-compression, post compression and in-vitro evaluation studies of developed formulation. All the formulations have showed acceptable Pharmacopeial standards.

The object of this research work was to formulate, develop and evaluate the Sustained Release SR Tablets of anti hypertensive drug Carvedilol. The tablets were prepared relatively small dose of 20 mg by direct compression method.

Article Information

A modified USP paddle method using minibaskets was used to study the effects of various formulations on in vitro dissolution of ibuprofen microspheres. Formulations containing waxes such as paraffin or ceresine wax without modifiers exhibited very slow dissolution profiles and incomplete release, which did not improve with increased drug loading or the preparation of smaller microspheres. Higher drug loading and decreased microsphere size increased the dissolution rate from microspheres containing modifier. An increase in the encapsulation dispersant concentration had little effect on the dissolution profiles. With appropriate modifiers, wax microsphere formulations of drugs with solubility characteristics similar to those of ibuprofen can offer a starting basis for predictable sustained release dosage forms.

Formulation and evaluation of sustained release tablets of carvedilol

Shailesh T. Prajapati, Amit N. Patel, Chhagan N. Tablets were prepared by melt granulation technique and evaluated for various evaluation parameters. Controlled-release CR formulations have been introduced into drug therapy with two main purposes: to reduce the number of single doses per day improving patient compliance of treatments and to decrease the fluctuations of plasma levels, in order to obtain better therapeutic efficacy and lower toxicity. There are many controlled-release pharmaceutical systems currently known, ranging from monolithic matrices, membrane reservoirs, erodible polymers, to the more technologically complex and sophisticated pH independent formulations, ion exchange resins, osmotically, and geometrically modified systems.

Rabeprazole, a member of substituted benzimidazoles, inhibits the final step in gastric acid secretions. This drug claims to cause fastest acid separation due to higher pKa , and more rapidly converts to the active species to aid gastric mucin synthesis. The most significant pharmacological action of Rabeprazole is dose dependent suppression of gastric acid secretion; without anticholinergic or H2-blocking action. It completely abolishes the hydrochloric acid secretion as it is powerful inhibitor of gastric acid.

Conventional drug delivery system for treating the angina and hypertension are not much effective as the drug do not reach the site of action in appropriate amounts. Thus potent and guarded therapy of this angina and hypertension disorder using specific drug delivery system is a challenging task to the pharmaceutical professionals. Most oftenly used method of regulating the drug release is to include it in a matrix system because of their pliability, hydrophilic polymer matrices are widely used in oral controlled drug delivery to obtain a desirable drug release pattern, methodical, and broad regulatory compliance. Formulation of Nifedipine sustained release matrix tablet was prepared by the polymers blend with to get desirable drug release profile. Evaluation parameters of formulated tablets were hardness, friability, thickness, drug content uniformity weight variation, and the in vitro drug release rate pattern.

Formulation and Evaluation of Sustained Release Matrix Tablets of Nifedipine

Author s : Katare Varsha B. DOI: Not Available. Address: Katare Varsha B. Powder blends were evaluated for bulk density, tapped density, Carr's index, Hausner's ratio and angle of repose. The compressed tablets were evaluated for various tests like weight variation, thickness, diameter, hardness, friability, dissolution and drug content. The results of all these tests were found to be satisfactory.

The aim of present investigation was to formulate and evaluate the sustained release matrix tablets of Repaglinide RPGN. Invitro drug release studies were performed by USP dissolution apparatus type-II paddle method using 0. Amongst all the 12 formulations, formulation F12 showed maximum drug release of It was observed from the kinetic studies that all the formulations followed first order kinetics and particularly the drug release from its dosage form was fickian diffusion F9, F12 , non-fickian diffusion F1-F8, FF Formulation F12 was subjected to stability studies and confirmed that formulation F12 was stable upto the period of 1 month.

Стратмор улыбнулся: - Это. Мы организуем утечку секретной информации. И весь мир сразу же узнает о ТРАНСТЕКСТЕ. Сьюзан вопросительно смотрела на. - Это совсем просто, Сьюзан, мы позволим правде выйти за эти стены. Мы скажем миру, что у АНБ есть компьютер, способный взломать любой код, кроме Цифровой крепости, - И все бросятся доставать Цифровую крепость… не зная, что для нас это пройденный этап.

 Сэр… видите ли, он у. - Что значит у вас? - крикнул директор. Это могло оказаться лучшей новостью за весь день. Смит потянулся к объективу камеры, чтобы направить его в глубь кузова. На экране промелькнула внутренняя часть мини-автобуса, и перед глазами присутствующих предстали два безжизненных тела у задней двери.

Однако Беккер был слишком ошеломлен, чтобы понять смысл этих слов. - Sientate! - снова крикнул водитель.

Тем не менее информация на экране казалась невероятной: NDAKOTA ETDOSHISHA. EDU - ЕТ? - спросила Сьюзан. У нее кружилась голова.  - Энсей Танкадо и есть Северная Дакота.

Стратмор пришел вчера с самого утра, и с тех пор его лифт не сдвинулся с места. Не видно, чтобы он пользовался электронной картой у главного входа. Поэтому он определенно. Бринкерхофф с облегчением вздохнул: - Ну, если он здесь, то нет проблем, верно.

В целях безопасности каждый файл, загруженный в ТРАНСТЕКСТ, должен был пройти через устройство, именуемое Сквозь строй, - серию мощных межсетевых шлюзов, пакетных фильтров и антивирусных программ, которые проверяли вводимые файлы на предмет компьютерных вирусов и потенциально опасных подпрограмм. Файлы, содержащие программы, незнакомые устройству, немедленно отвергались. Их затем проверяли вручную. Иногда отвергались абсолютно безвредные файлы - на том основании, что они содержали программы, с которыми фильтры прежде не сталкивались. В этом случае сотрудники лаборатории систем безопасности тщательно изучали их вручную и, убедившись в их чистоте, запускали в ТРАНСТЕКСТ, минуя фильтры программы Сквозь строй.

 - Это очень важно. Клушар заморгал.
