The main objective of this study was to develop mebeverine hydrochloride colon targeted drug delivery system using compression coating technique for effective treatment of irritable bowel syndrome. This work was mainly focused on the formulation & in-vitro evaluation of compression coated tablets of mebeverine hydrochloride with different pH dependent polymers like Eudragit L100-55, hydroxyprop...
It was found in our previous study that feeding silkworms with MoO2 nanoparticles (NPs) as a food additive enabled the incorporation of NPs into as-spun silk, which, turn, can be used to build electrodes for energy storage. However, aggregation observed at high fractional dosages. In order disperse fibrous silk and enhance specific capacitance carbonized more effectively, 0.5% (w/v) hydroxyprop...
The aim of the present investigation was to prepare extended release film coated matrix tablets of cephalexin using binary mixture of two grades of hydrophilic polymer, hydroxypropyl methyl cellulose (HPMC), by direct compression method. Results of the preliminary trials indicated that the polymers used have significant release retarding effect on the formulation. To study the effect of concent...
Oil palm empty fruit bunches (OPEFB) can be used as raw material for Hydroxypropyl Methylcellulose (HPMC). HPMC a French fries coating to reduce oil uptake. This research aims study the utilization of OPEFB coating. consists two stages. The first stage is cellulose extraction and synthesis. synthesis through alkalization, methylation, propylation, neutralization. second use with different conce...
photocatalytic degradation of diazinon from marine source using tio2/sio2 thin layer coated on glass
tio2 photo catalyst was prepared in presence of nano sio2 and hydroxy propyl cellulose (hpc) by sol gel method with titanium tetra isopropoxide (ttip) as titanium precursor. additional effect of hpc in preparation of nano catalyst, and photo catalyst properties measured and characterized by ft-ir, ft-raman and sem. the catalyst size and structural properties of the film were determined by .-ray...
The present investigation highlighted the formulation and release characterization of Ketorolac Tromethamine loaded matrix tablet. Various formulations of tablets were prepared by direct compression method along with Kollidon SR and Hydroxy Propyl Methyl Cellulose (HPMC) as release retardant polymers. Each of the formulated tablets contains 50mg Ketorolac Tromethamine. The evaluation involved p...
sustained release oral delivery systems are designed to achieve therapeutically effective concentrations of drug in the systemic circulation over an extended period of time. the purpose of the present investigation was to design and evaluate sustained release matrix tablets of nifedipine, a poorly water soluble drug, employing hydroxypropyl methyl cellulose ( hpmc) and ethyl cellulose ( ec) as ...
Amorphous solid dispersions (ASDs) have been extensively exploited as a strategy for improving the dissolution performance of poorly water-soluble drugs. However, factors underpinning the observed dissolution profiles are not clearly understood, and the choice of polymeric carriers is largely empirical. In the current study, the dissolution performance of a high drug loading ASD containing the ...
In this study, two kinds of cellulose derivatives (polyanionic cellulose (PAC) and hydroxypropylmethyl cellulose (HPMC)) were selected as stabilizers of Pd/Fe nanoparticles (NPs) to investigate their influences on the debromination performances of 2,2',4,4'-tretrabromodiphenyl ether (BDE47). Field emission scanning electron microscope (FE-SEM) images revealed that the cellulose-stabilized Pd/Fe...
