Abstract
The present invention provides a sustained-release composition obtained by gelating a compound such as a drug together with an oil or polysaccharide. This composition enables excellent sustained release of a contained compound such as a drug. Orally administered, the gel composition can stay in the stomach for a prolonged period by adjusting its specific gravity by varying the amount of oil or polysaccharide in the composition.
