Abstract
The present invention relates to a pharmaceutical preparation comprising omeprazole, an enantiomer thereof or a pharmaceutically acceptable salt thereof, and sodium bicarbonate, and a method for preparing the same. Specifically, the present invention relates to a pharmaceutical preparation in which sodium bicarbonate is first disintegrated so as to raise pH, and then omeprazole is dissolved such that the release properties of an active ingredient are improved, and thus the dissolution pattern and bioavailability of a drug can be enhanced.
