Abstract
A pharmaceutical composition capable of being disintegrated in an acidic environment, which comprises calcium polycarbophil and 1 to 80% by weight of a cellulose derivative such as carboxymethylcellulose or low substituted hydroxypropylcellulose based on the calcium polycarbophil. The pharmaceutical composition in a form of a tablet, a capsule, or granules is useful as a bulk-forming laxative or an antidiarrheic agent since it can be disintegrated readily in the stomach and form a complete dispersion of polycarbophil in the digestive tract.
