Abstract: An in vivo method is described for treating a subject for periodontal disease by placing a mixture of a glyceride composition and a therapeutic agent in the periodontal pocket of subject such that the therapeutic agent is released in a sustained manner. The glyceride composition is selected such that the mixture of the glyceride composition and the therapeutic agent is capable of forming a gel in the environment of the periodontal pocket. Also described is a sustained release delivery system comprising the mixture of the glyceride composition and therapeutic agent.

Abstract: The invention provides a tablet that will substantially dissolve rapidly in cool tap water or juice to yield a clear or almost clear calcium solution. The constituents of the tablet are calcium carbonate, fumaric acid and a water soluble third reactant wherein the calcium carbonate and the fumaric acid are present in approximately molar equivalent amounts and the third reactant is present in an amount sufficient to control the effervescence, allowing the tablet to dissolve completely without breaking apart and leaving any appreciable residue. The third reactant is preferably calcium lactate.
