PROBLEM TO BE SOLVED: To provide a drug for treating nerve injury, which is applied to a nerve injury site, can maintain a high concentration of the drug for a long period of time, and promotes nerve regeneration without stimulating the nerve even when embedded in a peripheral portion of the nerve injury site. To provide a sustained-release sheet to be contained and a method for producing the same. SOLUTION: The sheet is made of a non-woven fabric formed of nanofibers containing a drug such as vitamin B12 and a biocompatible polymer such as biodegradable aliphatic polyester, and is embedded in a peripheral portion of a nerve injury site to perform nerve regeneration. Drug sustained-release sheet for the treatment of nerve damage that promotes. [Selection diagram] None |
