In this study, a novel mesoporous silica nanoparticles drug carrier contributes to improving the solubility, dissolution, and the oral bioavailability of apigenin (AP). The apigenin of solid dispersion of mesoporous silica nanoparticles (AP-MSN) was prepared by physical absorption method and also, in-vitro drug release and in-vivo bioavailability performance were evaluated. Based on its solubil...

meloxicam is a poorly water soluble non steroidal anti-inflammatory drug and antipyretic agent. the aim of the present work was to investigate the effect of different types of carriers on in vitro dissolution of meloxicam. meloxicam solid dispersions were prepared by physical mixing, co-grinding and solvent evaporation methods with polyethylene glycol (peg) 6000. the effect of solubilization by...

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 release ...

cefquinome sulfate (cs) is a fourth-generation cephalosporin, which has been developed solely for veterinary use. it shows potent antibacterial activity against a broad spectrum of bacterial species. however, cefquinome is susceptible to hydrolysis, which limiting its clinical employment efficacies to some extent. so, in this study, to increase cefquinome sulfate biological half-life, a novel c...

ibuprofen solid dispersions were prepared by the solvent and fusion-solvent methods using polyethylene glycol (peg), polyvinylpyrrolidone (pvp), eudragit rs po, eudragit rl po and hydroxypropylmethylcellulose (hpmc) as carriers to improve physicochemical characteristics of ibuprofen. the prepared solid dispersions were evaluated for the flowability, solubility characteristics and dissolution be...

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...

Objective(s):Solid dispersion formulation is the most promising strategy to improve oral bioavailability of poorly water soluble drugs. The aim of this study was to compare the effect of polyvinylpyrrolidone K30 (PVP) and poloxamer-188 (PLX) as carrier in solid dispersion formulations of celecoxib (CLX). Materials and Methods: Solid dispersions of CLX:PVP or CLX:PLX were prepared at different r...
