  • Modified starch and process for its preparation
    Patent number: 5409712
    Abstract: Starch as a tablet excipient, in particular a disintegrant, is laden with one to twenty, in particular with three to ten, % by weight of physiologically safe compound which is soluble in a solvent which does not swell the starch. Edible organic acids, such as, for example, citric acid, 1-tartaric acid, adipic acid or fumaric acid, as well as polyvinylpyrrolidone--in particular relatively long-chain, straight-chain polyvinylpyrrolidone--are particularly suitable for this purpose.
