Chondroitinase compositions

摘要

This invention provides pharmaceutical compositions containing chondroitinase wherein a decrease in enzyme activity is very little even after long-term storage, and the pharmaceutical compositions are characterized in that they contain chondroitinase and a pharmaceutical carrier, and that an amount of reducing impurities per 1 g of said pharmaceutical carrier is 0.4 mL or less as a titer by a titration method with 0.01 N of ammonium ceric nitrate.
