The purpose of this work was to develop once daily sustained release (SR) matrix tablets of naproxen, an anti-inflammatory agent. The tablets were prepared by wet granulation method along with hydrophilic matrix materials like Methocel K 15M CR and Methocel K 100M CR. The granules were evaluated for bulk density, angle of repose, compressibility index, total porosity and drug content. The ...

In present study an attempt was made to formulate and to evaluate the sustain release Carvedilol matrix tablets by using METHOCEL K100LV CR, METHOCEL K100M CR and Xanthum Gum polymer. The tablets were prepared by direct compression method. The granules were evaluated by angle of repose, bulk density, tapped density and compressibility index, surface P. The formulated tablets were evaluated by w...

A well-defined and strictly controlled dissolution rate plays vital role in optimization of sustained release dosage form. For this purpose, a computer optimized technique, based on response surface methodology (RSM) utilizing quadratic equation factorial design has been widely used for designing different pharmaceutical formulations, which requires smaller number experimental runs is less time...

The purpose of study was to develop and characterize once daily extended release matrix tablets of Carbamazepine (CBZ), an antiepileptic drug. Tablets were prepared by wet granulation method. Methocel K15M CR and Methocel K100LV CR polymers were used as rate retarding agents in fourteen formulations. The granules were evaluated for angle of repose, loose bulk density, tapped bulk density, compr...

Indapamide, a low-dose thiazide-type diuretic, is used for the treatment of essential hypertension. In this study, we developed an indapamide sustained release formulation using Methocel K15M CR and Methocel K100M LVCR, starch 1500, talc and magnesium stearate considering technical feasibility and performed a comparative study with the release pattern. The tablets showed sustained release curve...

In this study an attempt was made to design and evaluate oral sustained release matrix tablets of ranolazine using Methocel K4M CR as the retardant polymer. Tablets were prepared by conventional wet granulation technique. Tablets were evaluated for parameters such as weight variation, hardness, friability and drug content. All the formulations showed compliance with pharmacopieal standards. In ...

Floating matrix tablets of losartan potassium were developed with an aim to prolong its gastric residence time and increase the bioavailability of drug. Rapid gastrointestinal transit could result in incomplete drug release from the drug delivery system above the absorption zone leading to diminished efficacy of the administered dose. The tablets were prepared by wet granulation technique, usin...

Kaposi's sarcoma (KS) associated herpesvirus (KSHV) is the etiological agent of KS. In vivo, KS is a tumor capable of spreading throughout the body, and pulmonary metastasis is observed clinically. In vitro, KSHV induces the invasiveness of endothelial cells. The KSHV open reading frame K15 is a KSHV-specific gene encoding a transmembrane protein. Two highly divergent forms of K15, the predomin...

The objective of this study is to design and evaluate sustained release tablets of Carbamazepine (CZP).The effects of various viscosity grades of Methocel(Methocel K4M, Methocel K100M and combination of both) on the release of Carbamazepine have been evaluated. Tablets were evaluated for physical and chemical parameters such as Hardness, Friability, Thickness, Weight variation, Drug content uni...
