This composition can be administered as an ordinary injection due to being pharmacologically acceptable. Compounding a drug with this composition makes it possible to provide a pharmaceutical that can be expected to have a long-term therapeutic effect even without frequent administration because the drug can be released over an extended period of time at the administration site. This composition also makes it possible to provide a pharmaceutical that need not be removed after treatment because the pharmaceutical is highly safe and finally disappears completely within the body. This composition can also be manufactured simply without using substances harmful to the human body, and can be applied to many drugs.
