Objective: To compare postprandial efficacy in type 2 diabetic patients given mitiglinide and sitagliptin, both of which are known to improve postprandial hyperglycemia, by using continuous glucose monitoring (CGM). %26lt;br%26gt;Methods: Eleven patients with type 2 diabetes were given mitiglinide 10 mg three times a daily or sitagliptin 50 mg once a day for 1 month and were hospitalized for 4 days and evaluated by CGM. On discharge, they were crossed over to the other regimen for 1 month of treatment/4 days of evaluation. The CGM data were used to compare each parameter for glycemic variability. %26lt;br%26gt;Results: The patients were 60 +/- 10 (mean +/- SD) years old, and had HbA1c value 7.3 +/- 0.9%. The pre-meal glucose levels before lunch were significantly lower with mitiglinide than with sitagliptin (116 +/- 26/131 +/- 34 mg/dl, p = 0.022). The AUC measuring over 140 mg/dl 3 h after breakfast (mitiglinide 4812 +/- 4219/sitagliptin 7807 +/- 6391 mg/dl +/- min, p = 0.042) and lunch (mitiglinide 5658 +/- 5856/sitagliptin 8492 +/- 7161, p = 0.050) was significantly lower with mitiglinide than with sitagliptin. %26lt;br%26gt;Conclusions: A CGM-based comparison showed that mitiglinide and sitagliptin were different in their glucose-lowering effects, where mitiglinide significantly improved hyperglycemia after breakfast and lunch, and significantly lowered pre-meal glucose levels before lunch, compared to sitagliptin.
