ABSTRACT:
There is provided a new technology that will allow the formulation of pharmaceutically active organic acid products at relatively high pH during storage. This affords the advantages of avoiding formulation with the acid form of the product, yet when the product is used, the pH will be reduced via a chemical reaction, thus forming the organic acid which is the active form of the product. A by-product of the reaction is a significant increase in temperature, thus adding to the efficacy of the organic acid.
