Objective: The purpose of this study was to determine the effect of adjuvant premeal pramlintide with postmeal insulin on postprandial hyperglycemia in children with type 1 diabetes mellitus (T1DM). Methods: Eight adolescents with T1DM on intensive insulin therapy participated in an open‐label, non‐randomized, crossover study, comparing postprandial glucose excursions in study A (prescribed insulin regimen and given premeal) vs. study B (pramlintide + insulin). Prandial insulin dose for study B was decreased by 20% and given postmeal, while pramlintide was given just before the meal. Blood glucose (BG), glucagon, and pramlintide concentrations were measured basally and at timed intervals during a 300‐min study period. Results: Postprandial incremental BG for the duration of the study was reduced in study B vs. study A with AUC (−60 to 300 min) (area under the curve) at 6600 ± 2371 vs. 20 230 ± 3126 mg/dL/min (367 ± 132 vs. 1124 ± 174 mmol/L/min) (p < 0.001). Glucagon concentration was suppressed for ∼120 min following administration of 30 μg of pramlintide and postmeal insulin (p < 0.003). No severe hypoglycemic episodes were experienced in this study. Conclusions: Postprandial hyperglycemia is considerably reduced in adolescents with T1DM when treated with fixed‐dose premeal pramlintide, and precisely calculated postmeal insulin, without significant side effects.
