Control release of fat soluble antioxidants from an oral formulation and method

Abstract

Oral formulation of particles made of an agglomeration of a plurality of seed granules or a single seed granule both surrounded by three layers and an outer gel coating. The seed granules are made of calcium carbonate with microscopic fissures. Disposed inside the fissures and in the interstitial spaces of the agglomerate seed granules are microscopic particles of alkali metal salts and other ions. Coating the agglomerate or single seed granules is an alkaline-resistant first layer made of microcrystalline cellulose and croscarmellose sodium that binds and protects the surrounding second layer. Surrounding the first layer is a second layer comprising a mixture of a flavonoid and polysaccharide or polypeptide binder or polymer gel. Surrounding the second layer is a third layer made of alkaline earth metal salt particles holding alkali metal hydroxide ions within a polysaccharide or polymer gel. Surrounding the third layer is at least one outer gel layer. The fourth and third layers dissolve in a low pH environment and release the fat soluble antioxidant and ions in the seed granule fissures.
