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...

This investigation describes the preparation and in vitro evaluation of gastro retentive floating tablets of atorvastatin calcium. Two hydrophilic cellulose derivatives, Methocel K4M and Methocel K15M CR were used in floating tablets as gel forming agents to control drug release. Sodium bicarbonate and citric acid were incorporated as gas generating agents. The tablets prepared by direct compre...

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 objective of the present study was to develop once-daily sustained-release matrix tablets of naproxen, one of the most potent non-steroidal anti-inflammatory agents used in the treatment of arthritic pain. The tablets were prepared by direct compression method using hydrophilic matrix materials like Methocel K4M CR and Methocel K15M CR. The tablets were subjected to measurement of thickness...

The present investigation describes the design and evaluation of monolithic gastro retentive dosage forms of diltiazem. Hydrophilic cellulose derivatives, Sodium alginate, Sodium carboxy methyl cellulose, Polyox, Methocel K100M in combination with Methocel E6LV are used as the rate controlling polymers. Sodium bicarbonate was incorporated as gas generating agent. Tablets were prepared by employ...

In order to reduce dosing frequency, a sustained release dosage form of betahistine dihydrochloride was developed as a twice daily controlled release tablet formulation that could be used to decrease vertigo resulted in Meniere's disease for a prolonged time. Six formulations were developed by using Methocel K4M CR, Methocel K15M CR and Methocel K 100 LVCR as single and combinations in differen...

Article history: Received on: 07/04/2013 Revised on: 29/04/2013 Accepted on: 14/05/2013 Available online: 30/05/2013 In the present study an attempt has been taken to develop Indapamide sustained release matrix tablet using Methocel K15M CR by direct compression method. Various amount of polymer was used in the five proposed formulations (F-1to F-5) for the study of release rate retardant effec...

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 ...

The present study has been performed to microencapsulate the antidiabetic drug of Vildagliptin to get sustained release of drug. The attempt of this study was to formulate and evaluate the Vildagliptin loaded microspheres by emulsion solvent evaporation technique using different polymers like Eudragit RL100, Eudragit RS100, Ethyl cellulose, and Methocel K100M. In vitro dissolution studies were ...
