Abstract
A novel delayed release pharmaceutical preparation which is free of added enzymes and thus is stable on storage is provided. The preparation comprises particles of the therapeutically effective agent, a water-soluble calcium salt, and, if desired, a filler material, stabilizer, and other additives uniformly embedded in a triglyceride of fatty acids with 12 to 18 carbon atoms, thereby forming a granular preparation of a grain size between about 0.1 mm. and about 1.0 mm. A process of producing such a preparation is also disclosed.
