1 Glipizide increases plasma insulin but not C-peptide level after a standardized breakfast in type 2 diabetic patients. Glipizide insulin Homo sapiens
2 After meal + glipizide, the blood glucose increase was sharply limited whereas the rise in plasma insulin was steeper and reached twice as high a level. Glipizide insulin Homo sapiens
3 Consequently, the areas under the curves (0-300 min) showed a marked reduction in blood glucose after meal + glipizide (2289 +/- 149 versus 3101 +/- 169 mmol X min/1; 2p less than 0.001), associated with a significant increase in plasma insulin (14219 +/- 3261 versus 7591 +/- 1173 microU X min/ml; 2p less than 0.025) but no significant change in plasma C-peptide (342 +/- 45 versus 326 +/- 34 pmol X min/ml; N.S.). Glipizide insulin Homo sapiens
4 The insulin/C-peptide molar ratio was thus significantly increased after meal + glipizide (0.41 +/- 0.06 versus 0.23 +/- 0.04 at the 60th min; 2p less than 0.02). Glipizide insulin Homo sapiens
5 The dissociation between the responses of insulin and C-peptide suggests that a single dose of 5 mg glipizide in Type 2 diabetic subjects may enhance availability of peripheral insulin by extrapancreatic mechanism(s). Glipizide insulin Homo sapiens
6 The dissociation between the responses of insulin and C-peptide suggests that a single dose of 5 mg glipizide in Type 2 diabetic subjects may enhance availability of peripheral insulin by extrapancreatic mechanism(s). Glipizide insulin Homo sapiens
