Type 2 Diabetes
Conditions
Keywords
insulin aspart 30, insulin aspart 70, insulin aspart, postprandial glucose and lipid metabolism, consecutive mixed meals
Brief summary
The aim of the study is to investigate meal-related treatment with either premixed Insulin Aspart 30, Aspart 70 and Aspart with regard to postprandial glucose, triglyceride and free fatty acids excursions after a standard breakfast and lunch.
Detailed description
Whereas the effects of each of the established types of insulin (remixed Insulin Aspart 30, Aspart 70 and Aspart) have been shown before, their specific glucose and lipid lowering capacities have so far not been investigated in a simulated physiological situation.
Interventions
Patients received insulin aspart before breakfast and before lunch.
Patients received biphasic insulin aspart 30 before breakfast and before lunch.
Patients received biphasic insulin aspart 70 before breakfast and before lunch.

Participant flow
Recruitment details
50 patients were screened and in total 20 randomizations were performed. After randomization 20 randomized subjects finished all three study visits.
Pre-assignment details
All subjects received all of the three insulins within various sequences in a randomized order. Randomisation lists for the insulin sequence were provided by a researcher otherwise not involved in the clinical trial performance.
