Abstract

Galactomannans whose hydroxyl groups are completely or partially in the form of low molecular weight aliphatic, araliphatic and/or aromatic ether or ester groups, and 20 to 80% of the mannose units present in the galactomannan chain form continuous mannose blocks of 2 to 20 mannose units which are not substituted by galactose groups, for encasings and/or embeddings of solid and/or liquid active substances, which release these active substances only in the colon or in the presence of glycolytic enzymes, process for the preparation thereof and pharmaceutical compositions prepared using such galactomannans are described.
