STEROID COMPOUND COMBINED WITH POLYSACCHARIDE.

摘要

A compound which can maintain a blood steroid level unchanged for long after administration, obtained by combining a steroid derivative with a polysaccharide directly or via a spacer. Desirable examples of the steroid derivative include ones having carboxyl and/or hydroxyl groups, and those of the spacer include polybasic carboxylic acids, while those of the polysaccharide include water-soluble ones such as dextran. When administered, the compound releases the steroid in the blood and the steroid level is kept constant for long.
