Dissolution rates of corticosteroids utilizing sugar glass dispersions.
A method of increasing the dissolution rates of some orally administered corticosteroids was investigated. This method involved glass dispersions using dextrose, galactose, and sucrose as the carriers. These dispersions were prepared by the fusion process and were subjected to a modified NF XIII dissolution rate determination. The results revealed a marked increase in the dissolution rate of the corticosteroids contained in the solid dispersions when compared to the dissolution rate of the plan corticosteroid powder. The increase in dissolution rates was attributed to the presence of the corticosteroid in a very fine state of subdivision and to the increased wettability of the corticosteroid powder.
