Ternary Amorphous Solid Dispersions

Characterization of Olanzapine – Solid dispersions.

Aim: To enhance the aqueous solubility of olanzapine by using the Solid dispersion technique. Solid dispersions of Olanzapine were prepared by the dispersion method using using PGS and SSG as carriers. Drug:carrier ratios such as 1:1, 1:2, 1:4, 1:6, 1:8 and 1:10 were tried for optimization. Characterization was done by phase solubility, in vitro release, saturation solubility, permeation, wetta...

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...

Limitations in the Pharmacopeial Dissolution Testing of Marketed Tacrolimus Amorphous Solid Dispersions

Improved supersaturation and oral absorption of dutasteride by amorphous solid dispersions.

In this study, amorphous solid dispersions containing dutasteride and various excipients, manufactured by spray-drying processes, were characterized to determine the effects on their ability to form supersaturated solutions and to identify the effects of supersaturation on increasing the bioavailability of dutasteride. The excipients included Eudragit E, hydroxypropyl-β-cyclodextrin (HP-β-CD), ...
