Pharmaceutical preparation for controlled release of a medicinal compound at a targeted site in the intestinal tract.

摘要

A pharmaceutical preparation controlled to release a medicinal compound at a targeted site in the intestinal tract comprises a medicinal compound-containing phase and an enteric coating phase provided around the medicinal compound-containing phase, said medicinal compound-containing phase releasing the medicinal compound quickly after a predetermined lag-time after the dissolution of the enteric coating phase. The pharmaceutical preparation makes it possible for the medicinal compound to be quickly released at any targeted site in the small intestine or the large intestine by the control of the amount of the enteric coating phase and the lag-time before the medicinal compound-containing phase starts to release the medicinal compound.
