Abstract
PURPOSE: To prepare an enteric drug using a cellulose derivative having excellent solubility to organic solvents, especially to alcohols, by coating a drug component with a carboxyalkylcellulose derivative.
CONSTITUTION: A drug component (e.g. enzymes such as pancreatin, etc.) is coated with a carboxyalkylcellulose derivative of formula (Gul is glucose anhydride skeleton of cellulose, having a molecular formula of C6H7O2; n is 2-5; R, R' are ester, ether, OH)(e.g. carboxyethylmethylcellulose) to afford the objective enteric drug. The drug is stable in artificial gastric juice, however, it disintegrates rapidly in artificial intestinal juice. It is also excellent in the storage stability, etc.
