ClinConnect Summary

Recently, we showed in both healthy, non-diabetic volunteers and in patients with type 1 (T1DM) and insulin-treated type 2 diabetes (T2DM) a 40-50% faster absorption of rapid-acting insulin analogues when administered by jet injection technology rather than by conventional insulin pen. The faster insulin action of insulin administration by jet injection may be especially advantageous for correction of hyperglycemia.

To investigate this, a open-label randomised controlled cross-over study will be performed in 20 adult patients (18-75 years) with T1DM or T2DM on basal-bolus insulin treatment...
