Abstract

A readily dissolved carrier material having sufficient rigidity for administration of drugs, nutrients, vitamins, biologically-active materials, foodstuffs and combinations thereof capable of rapid dissolution by saliva, bodily fluids or other liquid comprising an interim skeletal structure of an ammoniated gel or foam forming material, preferably a proteinaceous material, such as gelatin, that has been ammoniated, rigidified such as with maltodextrin, in the ammoniated state and deammoniated to leave spaces in place of the frozen ammonia. On dissolution by saliva, bodily fluids or other liquids, the composition becomes a liquid system. While the oral route is preferred, other routes may be used to administer the compositions of this method.
