Dipeptidyl peptidase IV inhibitors for treating diabetic patients with sulfonylurea secondary failure

摘要

An agent for treating diabetes with sulfonylurea secondary failure which comprises a dipeptidyl peptidase IV inhibitor. The agent of the present invention is an agent for treating diabetes with sulfonylurea secondary failure showing excellent insulin-secreting and hypoglycemic effects on even diabetic patients on whom a sulfonylurea compound or a fast-acting insulin secretagogue has no insulin-secreting effect and therefore no sufficient hypoglycemic effect.
