Study of gliclazide solid dispersion systems using PVP K-30 and PEG 6000 by solvent method

the effect of peg molecular weight and concentration on properties of gliclazide solid dispersion systems

Solubilization and Solid-State Characterization of Modafinil Solid Dispersions using PVP K 30

The objective of the present study was to improve the dissolution rate of Modafinil by solid dispersion (SD) systems in PVP-K 30. Drug contents were determined by UV Spectrophotometry at λmax of 259.5 nm. The phase solubility behavior of Modafinil in presence of various concentrations of carriers in distilled water was obtained at 37±2C. The dissolution of Modafinil increased with increasing am...

Peg Based Solid Dispersions of Gliclazide: a Comparative Study

In the present work, gliclazide loaded polyethylene glycol (PEG) based solid dispersions were prepared using fusion method in order to improve the solubility and dissolution rate of gliclazide. The compatibility of the drug with various formulation components was established. Solid dispersions (SDs) of gliclazide and polyethylene glycol (PEG 4000, 6000 and 8000) at three mass ratios (1:1, 1:3, ...

Preparation, characterization and in vitro dissolution studies of solid dispersion of meloxicam with PEG 6000.

The poor solubility and wettability of meloxicam leads to poor dissolution and hence showing variations in bioavailability. The present study is aimed to increase solubility and dissolution of the drug using solid dispersion techniques. The solid binary systems were prepared at various drug concentrations (5-40%) with polyethylene glycol 6000 by different techniques (physical mixing, solvent ev...

Investigation of Solid Dispersion Technique in Improvement of Physicochemical Characteristics of Ibuprofen Powder

     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 dissoluti...
