PREPARATION AND EVALUATION OF TERNARY MIXING ITRACONAZOLE SOLID DISPERSIONS BY SPRAY DRYING METHOD S.Rajarajan,
The present study aims to experiment the solid dispersion of poorly water soluble drug itraconazole as model drug by spray drying method with the use of PEG/HPMC polymer blends, the influence of polymer compatibility on the degree of molecular dispersion of itraconazole solid dispersions are prepared by ternary mixing and polymer blends are also evaluated for DSC, XRD and in vitro dissolution t...
متن کاملPreparation, characterization, and dissolution studies of naproxen solid dispersions using polyethylene glycol 6000 and labrafil M2130
Naproxen is a poor water soluble, non-steroidal analgesic and anti-inflammatory drug. The enhancement of oral bioavailability of poor water soluble drugs remains one of the most challenging aspects of drug development. Although salt formation, solubilization and particle size reduction have commonly been used to increase dissolution rate and thereby oral absorption and bioavailability of low wa...
متن کاملComparison of spray drying, electroblowing and electrospinning for preparation of Eudragit E and itraconazole solid dispersions.
Three solvent based methods: spray drying (SD), electrospinning (ES) and air-assisted electrospinning (electroblowing; EB) were used to prepare solid dispersions of itraconazole and Eudragit E. Samples with the same API/polymer ratios were prepared in order to make the three technologies comparable. The structure and morphology of solid dispersions were identified by scanning electron microscop...
متن کاملPreparation and Characterization of Celecoxib Dispersions in Soluplus®: Comparison of Spray Drying and Conventional Methods
The present study deals with characterization of dispersions of a poorly water-soluble drug, celecoxib (CLX) in polyvinyl caprolactame–polyvinyl acetate–polyethylene glycol graft copolymer (Soluplus® (SOL)) prepared by different techniques. Dispersions of CLX in SOL at different ratios (2:1, 1:1, 1:2, 1:4 and 1:6) were prepared by spray drying, conventional solvent evaporation and melting metho...

متن کاملA Modified Solvent Method for Preparation of Solid Dispersions
The first aim of the present investigation was to prepare solid dispersions to improve the dissolution properties of oxcarbazepine and quetiapine using PEG 6000 as a carrier with the help of two methods of preparations viz. spray drying and modified solvent method, and to compare the two methods. The second objective was to apply the modified solvent method for preparation of sustained re...
