ABSTRACT
AIMS:
To test whether jet injection of insulin resulted in faster correction of marked hyperglycaemia than when insulin is injected by a conventional pen in patients with diabetes.METHODS:
Adult, overweight or obese (BMI ≥25 and ≤40 kg/m(2)) patients with type 1 diabetes (n = 10) or insulin-treated type 2 diabetes (n = 10) were enrolled in a randomized, controlled, crossover study. On two separate occasions, patients were instructed to reduce insulin dose(s) to achieve marked hyperglycaemia (18-23 mmol/l). Subsequently, insulin aspart was administered either by jet injection or by conventional pen, in a dose based on estimated individual insulin sensitivity. Pharmacodynamic and pharmacokinetic profiles were derived from plasma glucose and insulin levels, measured for 6 h after injection.RESULTS:
After conventional injection, plasma glucose concentration dropped by ≥10 mmol/l after 192.5 ± 13.6 min. The jet injector advanced this time to 147.9 ± 14.4 min [difference 44.6 (95% confidence interval 4.3, 84.8); P = 0.03], except in 3 patients who failed to reach this endpoint. The time advantage exceeded 1.5 h in patients with a BMI above the median. Jet injection also reduced the hyperglycaemic burden during the first 2 h (2042 ± 37.2 vs 2168 ± 26.1 mmol/min; P = 0.01) and the time to peak insulin levels (40.5 ± 3.2 vs 76.8 ± 7.7 min; P < 0.001), but did not increase the risk for hypoglycaemia.CONCLUSIONS:
Administration of rapid-acting insulin by jet injection results in faster correction of marked hyperglycaemia in overweight or obese patients with insulin-requiring diabetes.Palabras clave
