  • THERAPEUTIC SOLUTION CONCENTRATE
    Publication number: 20180326069
    Abstract: A concentrated poly(ethylene glycol) solution that has good stability for extended storage is provided for use as a laxative. The concentrated solution comprises water, sodium benzoate, poly(ethylene glycol), and enough acid to yield a solution having a pH at 25° C. in the range 3.0-5.0. It is prepared and packaged to minimize the accumulation of degradation products.

  • Taste masking compositions comprising spray dried microcapsules containing sucralfate and methods for preparing same
    Patent number: 5013557
    Abstract: The present invention pertains to spray dried spheroidal microcapsules under about 150 microns in diameter which comprise in percentages by weight of the microcapsule composition (a) sucralfate present in an amount from about 1% to about 70%, and (b) a polymer soluble in the gastric fluids present in an amount from about 30% to about 99%. In another embodiment, the invention is directed at a taste masking composition which comprises a therapeutically effective amount of a spray dried spheroidal microcapsule core under about 150 microns in diameter and a matrix over the core wherein the taste masking composition comprises (A) a microcapsule core comprising in percentages by weight of the core composition (a) sucralfate present in an amount from about 1% to about 70%, and (b) a polymer soluble in the gastric fluids present in an amount from about 30% to about 99%; and (B) a matrix over the core comprising in percentages by weight of the matrix composition (a) a bulking agent present in an amount up to about 99.
