Abstract
The present invention relates to a stable pharmaceutical formulation comprising omeprazole, its enantiomer, or its pharmaceutically acceptable salt, and sodium bicarbonate, and a method for preparing the same. Specifically, the present invention provides a stable formulation by preventing omeprazole, its enantiomer, or its pharmaceutically acceptable salt, from coming in direct contact with sodium bicarbonate, to reduce the production of impurities.
