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. Formulation F9 have extended the release of Baclofen upto 12 h. Model fitting analysis for formulation F9 fitted in the zero order model and korsemeyer- peppas model.

Formulation and Evaluation of Sustained Release Matrix Tablets of Nifedipine

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.

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.

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.

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.

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. For the Sustained release formulation the dissolution time of the tablet must be optimized in order to have a prolonged release of drug in the dissolution profile. Save to Library. Create Alert.

Formulation and Evaluation of Sustained Release Matrix Tablets of Repaglinide

Methods: The ibuprofen matrix tablets were prepared by direct compression method using lactose as a diluent. Nineteen formulations of different polymer percentages were formulated, F1-F19 with 7. The formulation exhibited highest correlation R value in case of Hixson-Crowell model and the release kinetic study proved that the formulation showed erosion process, and shown to follow zero order kinetics. Conclusion: It was concluded that eudragit RL can be used for the preparation of sustained release tablet of ibuprofen.

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.

Но послушай: канадец сказал, что буквы не складывались во что-то вразумительное. Японские иероглифы не спутаешь с латиницей. Он сказал, что выгравированные буквы выглядят так, будто кошка прошлась по клавишам пишущей машинки. - Коммандер, не думаете же вы… - Сьюзан расхохоталась. Но Стратмор не дал ей договорить. - Сьюзан, это же абсолютно ясно. Танкадо выгравировал ключ Цифровой крепости на кольце.

Я поняла так, что весь смысл в том, чтобы его уничтожить. - Верно. Но я хочу иметь копию. Я хочу открыть этот проклятый файл и ознакомиться с созданной Танкадо программой. Сьюзан была столь же любопытна, как и ее шеф, но чутье подсказывало ей, что расшифровка алгоритма Цифровой крепости неразумна, какой бы интерес это ни представляло. В данный момент эта чертова программа надежно зашифрована и абсолютно безопасна.

Беккер старался не обращать внимания на легкий запах перца. Меган сказала, что, если тереть глаза, будет только хуже. Он даже представить себе не может, насколько хуже. Не в силах сдержать нетерпение, Беккер попытался позвонить снова, но по-прежнему безрезультатно. Больше ждать он не мог: глаза горели огнем, нужно было промыть их водой. Стратмор подождет минуту-другую.

Он двигался методично, обходя один ряд за другим. Наверху лениво раскачивалась курильница, описывая широкую дугу. Прекрасное место для смерти, - подумал Халохот.

Сьюзан вспомнила стандартную школьную таблицу. Четыре на шестнадцать. - Шестьдесят четыре, - сказала она равнодушно.  - Ну и .

ГЛАВА 108 Лифт Стратмора начал стремительно спускаться. В кабине Сьюзан жадно вдохнула свежий прохладный воздух и, почувствовав головокружение, прижалась к стенке лифта.
