摘要

PD-7038-64-SIL WARNER-LAMBERT COMPANY Morris Plains, U.S.A. New composition comprising a hydrophilic polymer and a hydrophilic material different therefrom A composition of matter capable of being formed into articles having substantial dimensional stability and improved dissolution characteristics, which composition comprises a medium and a phase, the medium functioning as a dispersion medium with respect to the phase, the phase likewise functioning as a disperse phase with respect to the medium, the phase being present in the composition at a concentration sufficient to effect an increase in dissolution of articles in comparison with the rate of dissolution of articles made from a composition absent the phase, the medium consisting of a solidified hydrophilic polymer and the phase comprising at least one hydrophilic material which is substantially insoluble in the medium comprising the hydrophilic polymer.
