Compositions, methods and uses for the treatment of diabetes and related conditions by controlling blood glucose level

1. A method for treating diabetes or a related disease selected from impaired glucose tolerance, impaired fasting glucose, insulin resistance, metabolic syndrome, postprandial hyperglycemia and overweight or obesity in a mammalian subject in need thereof, comprising administering to said subject an effective amount of a composition comprising:

ifenprodil and fenspiride,

fenspiride and torasemide,

fenspiride and triamterene, or

fenspiride and tolfenamic acid,

or salt(s), prodrug(s), or sustained release formulation(s) thereof.

2. The method of claim 1 , further comprising administering to said subject at least one anti-diabetic agent.

3. The method of claim 2 , wherein the at least one anti-diabetic agent is selected from acarbose, acetohexamide, alogliptin, berberine, bezafibrate, bromocriptine, buformin, carbutamide, chlorpropamide, chromium picolinate, ciprofibrate, clofibrate, colesevelam, dexfenfluramine, dutogliptin, exenatide, fenofibrate, gemfibrozil, gemigliptin, glibenclamide, glibornuride, glicetanile, gliclazide, glimepiride, glipizide, gliquidone, glisentide, glyclopyramide, imidapril, insulin, inulin, lipoic acid, linagliptin, liraglutide, mecobalamin, metformin, miglitol, mitiglinide, nateglinide, orlistat, phenformin, pioglitazone, pramlintide, repaglinide, rosiglitazone, saxagliptin, sitagliptin, tolazamide, tolbutamide, vildagliptin or voglibose, or salt(s), prodrug(s), or sustained release formulation(s) thereof.

4. The method of claim 3 , wherein the at least one anti-diabetic agent is metformin, or a salt, prodrug, or sustained release formulation thereof.

5. The method of claim 4 comprising administering to said subject:

ifenprodil and fenspiride and metformin,

fenspiride and torasemide and metformin,

fenspiride and triamterene and metformin, or

fenspiride and tolfenamic acid and metformin,

or salt(s), prodrug(s), or sustained release formulation(s) thereof.

6. A method for controlling blood glucose level in a mammalian subject in need thereof, comprising administering to said subject a composition comprising fenspiride, or a salt, prodrug or a sustained release formulation thereof in combination with at least one further compound selected from ifenprodil, torasemide, triamterene, tolfenamic acid, or salt(s), prodrug(s) or sustained release formulation(s) thereof.

7. The method of claim 6 , wherein the mammalian subject is suffering from diabetes or from a related disorder selected from impaired glucose tolerance, impaired fasting glucose, insulin resistance, metabolic syndrome, postprandial hyperglycemia and overweight or obesity.

8. A method for decreasing insulin resistance in a mammalian subject in need thereof, comprising administering to said subject a composition comprising fenspiride, or a salt, prodrug or a sustained release formulation thereof in combination with at least one further compound selected from ifenprodil, torasemide, triamterene, tolfenamic acid, or salt(s), prodrug(s) or sustained release formulation(s) thereof.

9. A method for increasing or stimulating glucose uptake in adipocytes or muscular cells in a mammalian subject in need thereof, comprising administering to said subject a composition comprising fenspiride or a salt, prodrug or a sustained release formulation thereof in combination with at least one further compound selected from ifenprodil, torasemide, triamterene, tolfenamic acid, or salt(s), prodrug(s) or sustained release formulation(s) thereof.

10. The method of claim 1 , wherein the mammalian subject is suffering from type 2 diabetes.

11. The method of claim 1 , wherein the composition further comprises a pharmaceutically acceptable carrier or excipient.

12. The method of claim 1 , wherein the compounds are formulated or administered together, separately or sequentially.

13. The method of claim 1 , wherein the composition is administered repeatedly to the subject.
