Application Number: | 09/302,469 |
Claims: | 1. A method for treating diabetic complications in a mammal in need thereof, which comprises administering to such mammal a therapeutically effective amount of an insulin sensitivity enhancer in combination with a fibrate compound. 2. Method according to claim 1, wherein the insulin sensitivity enhancer is pioglitazone or its hydrochloride. 3. Method according to claim 1, wherein the insulin sensitivity enhancer is troglitazone. 4. The method according to claim 1, wherein the insulin sensitivity enhancer and fibrate compound are mixed together to form an admixture and the admixture is administered to the mammal. 5. The method according to claim 1, wherein the insulin sensitivity enhancer and fibrate compound are not mixed together but are administered independently to the mammal. 6. The method according to claim 1, wherein the aldose reductase inhibitor is selected from the group consisting of bezafibrate, beclobrate, binifibrate, ciplofibrate, clinofibrate, clofibrate, clofibric acid, etofibrate, fenofibrate, gemfibrozil, nicofibrate, pirifibrate, ronifibrate, simfibrate and theofibrate. 7.

The pharmaceutical composition according to claim 7, wherein the insulin sensitivity enhancer is pioglitazone or its hydrochloride. 9. The pharmaceutical composition according to claim 7, wherein the insulin sensitivity enhancer is 5-[[4-[2-(methyl-2-pyridylamino)ethoxy]phenyl]-methyl]-2,4-thiazolidinedio ne or its pharmacologically acceptable salt. 10. The pharmaceutical composition according to claim 7, which is for prophylaxis or treatment of diabetes. 11. The pharmaceutical composition according to claim 7, which is for prophylaxis or treatment of diabetic complications. 12. The pharmaceutical composition according to claim 7, wherein the fibrate compound is selected from the group consisting of bezafibrate, beclobrate, binifibrate, ciplofibrate, clinofibrate, clofibrate, clofibric acid, etofibrate, fenofibrate, gemfibrozil, nicofibrate, pirifibrate, ronifibrate, simfibrate and theofibrate. 13. A method for treating diabetes in a mammal in need thereof, which comprises administering to such mammal a therapeutically effective amount of an insulin sensitivity enhancer in combination with a fibrate compound wherein the insulin sensitivity enhancer is selected from the group consisting of 5-[4-[2-(3-ethyl-2-pyridyl)ethoxy]benzyl]-2,4-thiazolidinedione; 5-[4-[2-(4-ethyl-2-pyridyl)ethoxy]benzyl]-2,4-thiazolidinedione; 5-[4-[2-(5-ethyl-2-pyridyl)ethoxy]benzyl]-2,4-thiazolidinedione; 5-[4-[2-(6-ethyl-2-pyridyl)ethoxy]benzyl]-2,4-thiazolidinedione; (R)-(+)-5-[3-[4-[2-(2-furyl)-5-methyl-4-oxazolylmethoxy]-3-methoxyphenyl]pr opyl]-2,4-oxazolidinedione; 5-[[3,4-dihydro-2-(phenylmethyl)-2H-1-benzopyran-6-yl]methyl]-2,4-thiazolid inedione; 5-[[4-[3-(5-methyl-2-phenyl-4-oxazolyl)-1-oxopropyl]phenyl]methyl]-2,4-thia zolidinedione; 5-[2-(5-methyl-2-phenyl-4-oxazolylmethyl)benzofuran-5-ylmethyl]-2,4-oxazoli dinedione; 5-(2-naphthalenylsulfonyl)-2,4-thiazolidinedione 5-[[4-[2-(methyl-2-pyridylamino)ethoxy]phenyl]-methyl]-2,4-thiazolidinedion e; and their pharmacologically acceptable salts. 14.
