description | A shaped chitin body containing a high content of a physiologically active substance, such as a drug to be used for the cure or prevention of disease, is prepared by incorporating said physiologically active substance into a dope comprising (a) a water-insoluble chitin, (b) lithium chloride, and (c) N-methylpyrrolidone and/or dimethylacetamide, with the amount of said physiologically active substance incorporated being 0.5 wt. % or more with respect to the amount of the chitin contained in said dope, and thereafter coagulating the resulting mixture with a coagulant to obtain a shaped body. The high content of the physiologically active substance thus incorporated in the shaped chitin can be slowly released therefrom over a long period of time. The shaped-chitin of the present invention is characterized by long duration of the physiological activity of the active substance contained therein. |
