Insulin glulisine has a faster onset of action compared with insulin aspart in healthy volunteers.

AIM: Because of its zinc-free formulation insulin glulisine (GLU) might have a faster onset of action than other short-acting analogues. We compared the pharmacokinetics and pharmacodynamics of GLU with those of insulin aspart (ASP).
METHODS: Twelve healthy subjects, aged 18-65 years, participated in this randomized, double-blind, crossover trial. Subjects received 0.2 U/kg GLU or ASP under euglycaemic glucose-clamp conditions.
RESULTS: GLU showed a significantly higher early metabolic effect (area under the glucose infusion rate (GIR) curve in the first 30 min AUC-GIR (0-)30↓ min 30.3 ± 26.4 vs. 16.2 ± 18.4 mg/kg, P = 0.0421) than ASP, an earlier onset of action (time to 10% of GIR (max) (GIR (max)-t (10%)) 9 vs. 17 min, P = 0.0146) and a faster absorption (shorter times to 10% and 20% of INS (max,) P = 0.0005 each).
CONCLUSIONS: As demonstrated previously versus lispro, GLU, the only analogue formulated without zinc, also has an earlier onset of action than ASP. © Georg Thieme Verlag KG Stuttgart · New York.
