Comparison of physicomechanical properties of films prepared from organic solutions and aqueous dispersion of Eudragit RL
BACKGROUND AND THE PURPOSE OF THE STUDY Mechanical properties of films prepared from aqueous dispersion and organic solutions of Eudragit RL were assessed and the effects of plasticizer type, concentration and curing were examined. METHODS Films were prepared from aqueous dispersion and solutions of Eudragit RL (isopropy alcohol-water 9:1) containing 0, 10 or 20% (based on polymer weight) of ...
متن کاملThe Study of Piroxicam Dissolution from Eudragit Rs-coated Pellets
The objective of this work was to study the dissolution process from piroxicam pellets, coated with Eudragit RS 30 D by fluidized bed, in order to achieve an enteric release of the drug. The coating product contains a methacrylic copolymer which is insoluble, but permeable. The drug-loaded pellets were prepared by extrusionspheronization using microcrystalline cellulose (Avicel PH 101) as a sph...

هدف از این تحقیق بررسی برخی عوامل ادراکی واحساسی یعنی استفاده از شیوه های یادگیری زبان ، انگیزه ها ونگرش نسبت به زبان انگلیسی در رابطه با زمینه زبانی زبان آموزان می باشد. هدف بررسی این نکته بود که آیا اختلافی چشمگیر میان زبان آموزان دو زبانه و تک زبانه در میزان استفاده از شیوه های یادگیری زبان ، انگیزه ها نگرش و سطح مهارت زبانی وجود دارد. همچنین سعی شد تا بهترین و موثرترین عوامل پیش بینی کننده ...
15 صفحه اولDevelopment and In vitro Evaluation of Flurbiprofen Microcapsules Prepared by Modified Solvent Evaporation Technique
Purpose: To develop modified release microcapsules of flurbiprofen for sustained release and reduced gastrointestinal side effects. Method: A co-polymer containing Eudragit RS 100 and hydroxypropyl methylcellulose (HPMC) in different drug/co-polymer ratios was used for microencapsulation of flurbiprofen by modified emulsion solvent evaporation (MESE) technique. The microcapsules were evaluated ...
متن کاملBenzoic Compounds Removal from Aqueous Solutions by Acidic Silk: Equilibrium and Kinetic Study
Background & Aims of the Study: p-Chloronitrobenzene is a benzoic compound that widely used in many chemical industrials. p-Chloronitrobenzene may be absorbed through the skin and is suspected to causing cancer. So, developing an easy method to remove of it from the environment is necessary. Equilibrium isotherms and adsorption kinetics of p-Chloronitrobenzene onto modified sil...
