The objective of this project was to improve the solubility poorly water soluble drugs, namely cefuroxime axetil by formulating solid dispersions with hydrophilic polymer. Hydroxypropyl methyl cellulose (HPMC), polyvinyl pyrrolidine (PVP) and polyethylene glycol (PEG) were used as polymeric carriers for preparation dispersion. Solid prepared solvent extraction method. Interaction effect HPMC, P...

The aim of the present study was to minimize the unwanted toxic effects of Diltiazem Hydrochloride (DTZ) by kinetic control of drug release. DTZ was incorporated into the biocompatible and biopolymer blends of chitosan (CH) and micro crystalline cellulose (MCC) matrix pellets using pelletization technique. Solid, free flowing matrix pellets and yields up to 97.5 %. More than 98 % of the isolate...

The aim of present work was to optimize the effect of Ethyl Cellulose (EC) and Polyvinyl Pyrrolidone (PVP) concentration in extended release solid dispersion of Glibenclamide using combination of hydrophilic and hydrophobic polymers such as Polyvinyl Pyrrolidone and Ethyl cellulose. The advantage of solid dispersion technique provides a unique approach to particle size reduction and increased r...

The objective of present work is to investigate the enhancement of dissolution profile for oral delivery of Fexofenadine Hydrochloride (FH) through solid dispersion (SD) technique by the method of solvent evaporation. The SD was prepared by using ethanol as a solvent. Tablets were formulated containing solid dispersion of FH and compared with tablets of same formula without solid dispersion of ...

Chronobiology of rheumatoid arthritis (RA) was studied using a standard adjuvant arthritis animal model. Chronopharmacology of ketoprofen, and its solid dispersion forms was also studied. Temporal variations in the degree of articular inflammation (paw volume) and progression of articular destruction were studied by injecting Freund's Complete Adjuvant (FCA) at 0800 and 2000 hrs. Temporal varia...

Cr-incorporated UN (Cr-UN) composite fuels with different Cr amounts up to 10 wt% are fabricated by spark plasma sintering, and their microstructure phase heterogeneity analyzed. Highly densified homogeneous distribution identified for the pellets, demonstrating a liquid sintering characteristic enriched on grain boundaries. A ternary U2CrN3 forms in Cr-UN matrix of 5 wt%. The SPS pellets displ...

The aim of this study was to develop celecoxib-polyvinylpyrrolidone (PVP) solid dispersion nanoparticles with and without surfactant using the supercritical antisolvent (SAS) process. The effect of different surfactants such as gelucire 44/14, poloxamer 188, poloxamer 407, Ryoto sugar ester L1695, and d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) on nanoparticle formation and dissolu...

OBJECTIVES 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 ra...

      In order to enhance in vitro dissolution and content uniformity of poorly soluble drug glimepiride by preparing solid dispersions using modified solvent fusion method, solid dispersions of drug were prepared by modified fusion solvent method using PEG 6000 and PVP K25 (as carrier). Eight batches (F1-F8) were prepared by Factorial design (23) by taking three ...
