  • Pharmaceutical compositions including alginates and methods of preparing and using same
    Patent number: 7776839
    Abstract: A pharmaceutical composition is provided for use in the healing of cells containing about 0.0001 percent weight per volume (% w/v) to about 2% w/v of an alginic acid or a salt of alginic acid having a molecular weight in the range of greater than about 250,000 to about 1,000,000, provided that if the composition additionally contains an alginic acid or a salt of alginic acid having a molecular weight in the range of about 20,000 to about 250,000, it is present in an amount of less than 1% w/w. The use of the pharmaceutical composition for the healing cells in a mammal, preferably mucosal cells is also provided.

  • Pepsin inhibition by alginates
    Publication number: 20030176394
    Abstract: Certain alginates exhibit a superior ability to inhibit the proteolytic activity of pepsin and/or gastric juice. In particular, alginates having a molecular weight between 40,000 and 350,000 exhibit a superior inhibition of the proteolytic activity of pepsin and gastric juice by over 50% when measured using an N-terminal assay.
