We compared the postprandial blood glucose (BG)-levels following preprandial regular insulin or lispro insulin before and after eating in adolescents with diabetes. Lispro is a rapidly absorbed insulin analogue. Lispro insulin injected immediately before breakfast reduced the postprandial BG-rise significantly compared to the 20 min preprandially administered regular insulin (P<0.01). Postprandial lispro injection resulted in similar BG values as the standard treatment with regular insulin 20 min preprandially.
Conclusion Lispro insulin injected immediately before the meal leads to lower postprandial BG levels and seems to be an option for teenagers who use multiple preprandial insulin injections. Postprandial lispro administration could be a benefit in certain situations since it resulted in similar BG values to preprandial regular insulin.
