ABSTRACT:
A microgranular preparation having a core of biologically active material that is encapsulated by a water soluble film that is covered by an enteric coating of either an alkali soluble, acid insoluble polymer or a high molecular weight polymer whose structure is substituted with or contains windows of fatty acids or other material capable of being solubilized by intestinal juices. Useful for protecting pH sensitive and other biologically active materials from inactivation or contact with the stomach or rumen, and releasing the same in active form in the intestinal tract, particularly the duodenum.
