STERIOD 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 watersoluble ones such as dextran. When administered, the compound releases the steroid in the blood and the steroid level is kept constant for long.
