Abstract

The present invention provides a pharmaceutical preparation comprising: an inner core including an acidulant and bambuterol or a pharmaceutically acceptable salt thereof as an active ingredient; and a coating layer for coating the surface of the inner core, wherein the coating layer includes both a pH-dependent polymer and a pH-independent polymer. When the preparation of the present invention is orally administered, the preparation releases the active ingredient thereof after an elapse of a predetermined delay time after the preparation has been passed from the stomach to the intestine of a patient, thus providing medicinal effects during the time when asthmatic symptoms become severe.
