Definitions
- the present invention relates to a therapeutic agent for secondary ineffective diabetes, which comprises a dipeptidyl peptidase IV (sometimes abbreviated as DPP-IV in the present specification) inhibitor.
- a therapeutic agent for secondary ineffective diabetes which comprises a dipeptidyl peptidase IV (sometimes abbreviated as DPP-IV in the present specification) inhibitor.
- Sulfol perrea compounds (hereinafter sometimes abbreviated as SU agents) are widely used as first-line drugs for oral hypoglycemic agents.
- SU agents Sulfol perrea compounds
- continuous administration of the SU agent to diabetic patients does not produce a sufficient blood glucose lowering effect, that is, sulfonylurea secondary failure.
- DPP-IV inhibitors are known to be useful as therapeutic agents for diabetes and the like (for example, see Patent Document 1).
- Patent Document 1 International Publication No. WO02Z062764 pamphlet
- An object of the present invention is to provide a sulfoleurea compound or a fast-acting insulin secretagogue that does not provide an insulin secretion effect and thus cannot provide a sufficient blood glucose lowering effect. It is an object of the present invention to provide a therapeutic agent for secondary ineffective diabetes having excellent insulin secretion effect and hypoglycemic effect.
- a further object of the present invention is to provide an excellent drug which is free from side effects such as vascular complications and hypoglycemia induced when an insulin preparation is administered (especially long-term administration) to patients with sulfollurea secondary ineffective diabetes. It is intended to provide a therapeutic agent for sulfonylurea secondary ineffective diabetes having an excellent therapeutic effect.
- a therapeutic agent for secondary ineffective diabetes comprising a sulfonylurea containing a DPP-IV inhibitor
- a method for treating sulfonylurea secondary ineffective diabetes in a mammal which comprises administering to the mammal an effective amount of a dipeptidyl peptidase IV inhibitor.
- an insulin secretagogue for patients with secondary ineffective diabetes comprising a dipeptidyl peptidase IV inhibitor
- a method for promoting insulin secretion in a patient with secondary diabetics of sulfo-lurea which comprises administering an effective amount of a dipeptidyl peptidase IV inhibitor to the patient.
- the therapeutic agent for sulfonylurea secondary ineffective diabetes of the present invention is not suitable for diabetic patients because a sulfonylurea compound or a rapid-acting insulin secretagogue does not provide an insulin secretion effect, and thus does not provide a sufficient blood glucose lowering effect. However, it has excellent insulin secretion and blood glucose lowering effects.
- the therapeutic agent for secondary ineffective diabetes of the present invention has side effects (eg, vascular complications, hypoglycemia) and glucagon-like peptide (GLP) induced when an insulin preparation is administered (particularly for a long period of time). It is used safely without any side effects (eg, hypoglycemia, vomiting) induced when -1 is administered.
- side effects eg, vascular complications, hypoglycemia
- GLP glucagon-like peptide

- the compound may be peptide or non-peptidic, but may be non-peptidic, but is preferably non-peptidic.
- the DPP-IV inhibitor may have a different form before and after administration to a living body, as long as the DPP-IV inhibitory activity is maintained. That is, the DPP-IV inhibitor may be an “active metabolite” having DPP-IV inhibitory activity after being converted into a conformational form after being metabolized in vivo. Further, the DPP-IV inhibitor may be a “prodrug” which is converted into an active form by a reaction with an enzyme, stomach acid or the like under physiological conditions in a living body.
