Abstract
Abstract An antidiabetic agent containing a spherical carbon (e.g., an activated spherical carbon or a spherical carbonaceous adsorbent) as an active ingredient. The antidiabetic agent can be used for treating diabetes, preferably by using the agent internally as an oral medicine and will not be painful to a patient at an injection site, unlike conventional injections of insulin. Moreover, unlike conventional antidiabetic agents, the antidiabetic agent of the present invention will not induce hypoglycemia.
