Abstract:
Mucoadhesive tablets of montelukast sodium were prepared in order to release the drug for a prolonged period of time so as to reduce the frequency of administration. Direct compression technique was applied using the mucoadhesive polymers which were Methocel K4M CR, Methocel K15M CR, Methocel K100M CR and Eudragit RLPO. Highest percent release of drug after 8 hours was 76% for Methocel K4M CR, 72.13% for Methocel K15M CR, 65.68% for Methocel K100M CR, 65.53% for the combination of Methocel K15M CR and Eudragit RLPO.

Abstract:
Introduction: Cefadroxil is a first-generation cephalosporin and is very effective against Gram positive and Gram negative infections. Cefadroxil is an antibiotic agent which has high absorption in the upper part of the gastrointestinal tract (GIT). Conventional Cefadroxil tablets produce rapid and relatively high peak blood level and require frequent administration to keep the plasma drug level at an effective range. The present study was carried out with an objective of preparation and in vivo evaluation of floating tablets of using Cefadroxil as a model drug using Eudragit polymers to impro

Abstract:
Floating microspheres loaded with Nizatidine were prepared using solvent- evaporation method using HPMC, Eudragit RL 100, Eudragit RLPO in different ratio polymers. Drug and polymer in proportion of drug and polymers were dissolved in 1:2 mixture of solvent system of ethanol and dichloromethane. Floating microspheres of Nizatidine were prepared by a solvent diffusion- evaporation method. The nature of polymer influenced the physical characteristics as well as floating behaviour of the microspheres. In vitro buoyancy and in vivo studies confirmed the excellent floating properties of HPMC, Eudra

Abstract:
Metformin HCl microspheres were prepared with the aim of increasing its bioavailability and decreasing gastrointestinal side effects by means of sustained action. Eudragit RSPO and Eudragit RLPO, polymers of different permeability characteristics were used to prepare different microspheres. Emulsification solvent evaporation technique using acetone as the internal phase and liquid paraffin as the external phase was the method of choice. Six formulations were prepared using two polymers.

Abstract:
The present work was based on the development and characterization of unfolding type gastroretentive dosage form appropriate for controlled release of enalapril maleate. Drug loaded films were prepared by solid dispersion technique using methocel K15 and eudragit RSPO and eudragit RLPO as polymers and polyethylene glycol 400 (PEG 400) as the plasticizer. The film folded in a capsule shell was shown to unfold in the gastric juice and provide drug release up to 12 h in the acidic medium. Formulations provided satisfactory unfolding characteristics allowing expansion to remain in the stomach. For

Abstract:
The purpose of the present studies was to develop and characterize sustained release tablets of Carbamazepine, an antiepileptic drug. Tablets were prepared by direct compression method. In the formulation, the active drug was taken 200 mg in every formulation. Methocel K4M, Methocel K15M CR, Methocel K100LV CR, Eudragit RSPO and Eudragit RLPO polymers were used as rate retarding agents in twenty four formulations (F-1 to F-24). The effect of hydrophilic polymer PEG 6000 as channeling agent with Methocel K4M was observed in four formulations (F-5 to F-8). The granules were evaluated for angle o

Abstract:
The bioavailability of the antihypertensive drug valsartan can be enhanced by various microencapsulation methods. In the present investigation, valsartan-loaded polymeric nanoparticles were manufactured from Eudragit® RLPO using an emulsion–solvent evaporation method. Polyvinyl alcohol (PVA) was found to be a suitable stabilizer for the nanoparticles, resulting in a monodisperse colloid system ranging in size between 148 nm and 162 nm. Additionally, a high encapsulation efficiency (96.4%) was observed. However, due to the quaternary ammonium groups of Eudragit® RLPO, the stabilization of the d
