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.

Pharmaceutical preparation having excellent dissolution properties, containing esomeprazole and sodium bicarbonate

The present invention relates to a stable pharmaceutical composition comprising omeprazole, its enantiomer, or its pharmaceutically acceptable salt, and sodium bicarbonate. Specifically, the present invention relates to a pharmaceutical composition with improved stability comprising a low dose of sodium bicarbonate, so that it has improved dissolution rate and bioavailability and also reduces side effects resulting from a high dose of sodium bicarbonate.

Stable pharmaceutical composition comprising esomeprazole and sodium bicarbonate

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.

Pharmaceutical formulation comprising esomeprazole and sodium bicarbonate

The present invention relates to a pharmaceutical composition with enhanced stability, containing pemetrexed or a salt thereof, and a preparation method therefor. The present invention provides an injection preparation in liquid form containing pemetrexed, capable of ensuring sufficient stability during circulation and storage by selection of an optimum material and setting of an optimum concentration range in order to secure the stability of pemetrexed. The present invention can provide a pemetrexed preparation which is readily commercially prepared, can prevent microbial contamination occurring during lyophilization or reconstitution, and has enhanced convenience of administration and stability.
