Аннотация:

Solid dispersions (SDs) of indomethacin with polyethylene glycol 1500 (PEG-1500) were studied to determine their effect on indomethacin solubility. Production of SDs increased the solubility and dissolution rate of indomethacin in H2O. The solubility and dissolution rate of indomethacin from SDs increased by 1.8 – 2.2 and 3.1 – 4.4 times, respectively. Indomethacin became less crystalline and then amorphous during preparation of the SDs. Dissolution of the SDs solubilized indomethacin and formed colloidal solutions. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.
