To prolong the residence time of dosage forms within the gastrointestinal tract until all drug is released at the desired rate is one of the real challenges for oral controlled-release drug delivery systems. This study was designed to develop a controlled-release floating matrix tablet and floating raft system of Mebeverine HCl (MbH) and evaluate different excipients for their floating behavior...

To examine newly developed single-unit of oral sustained release dosage form Simvastatin (SS) have been prepared by the wet granulation method. The hydrophilic matrix was prepared with xanthan gum with additives MCC PH101. On the in vitro drug release was studied. The studies indicated that the drug release can be modulated by varying the concentration of the polymer and fillers. Various pharma...

In this present study an attempt has been made to evaluate glyceryl monostearate (GMS) as a rate retarding material to sustain the release ciprofloxacin hydrochloride from the matrix tablet. The solubility of ciprofloxacin hydrochloride was studied. The physical parameters of the prepared tablets were also evaluated. Release kinetics of ciprofloxacin hydrochloride from this sustained release ma...

Monolithic matrix tablets of ambroxol hydrochloride were formulated as sustained release tablets employing hydroxypropyl methylcellulose polymer, and the sustained release behaviour of the fabricated tablets was investigated. Sustained release matrix tablets containing 75 mg ambroxol hydrochloride were developed using different drug polymer ratios of hydroxypropyl methylcellulose. Tablets were ...

the main objective of the present study was to formulate gastroretentive effervescent sustained release drug delivery systems of risperidone floating tablets with the help of methocel® k15, ethocel® standard 7fp premium, eudragit ® rs100 sustained release polymers to improve its safety profile, bioavailability and patient compliance. risperidone floating tablets were formulated by wet granulati...

The aim of this study is to develop a once-daily sustained release matrix tablet of ibuprofen using hydroxypropyl methylcellulose (HPMC) as release controlling factor and to evaluate drug release parameters as per various release kinetic models. In order to achieve required sustained release profile tablets were directly compressed using Avicel pH 101 and Magnesium stearate. The formulated tabl...

The present study was aimed to develop antihypertensive sustained release matrix tables of valsartan Angiotensin II receptor antagonist, using hydroxypropylmethylcellulose alone and in combination with ethyl cellulose as the matrix material in different proportion by wet granulation method. The granules were evaluated for angle o f repose, bulk density and Compressibility index. The tablets wer...
