Coverage of postprandial blood glucose excursions with inhaled technosphere insulin in comparison to subcutaneously injected regular human insulin in subjects with type 2 diabetes.

T echnosphere Insulin (TI) is a formulation of regular human insulin (RHI) that provides efficient pulmonary administration (1) and demonstrates unique pharmacokinetic and pharmacodynamic properties compared with subcutaneous RHI, rapid-acting insulin analogs, and other inhaled insulins (2). Administration of TI results in a time to maximum insulin concentration of 15 min, with almost complete absorption within 3 h (3,4). With an onset of action comparable to intravenous insulin, TI represents the first formulation that approaches the physiological early insulin release. In this study, we evaluated the efficacy and safety of TI compared with subcutaneous RHI in covering prandial insulin needs. We measured blood glucose excursions after a meal challenge after individual titration of either insulin formulation during a 7-day treatment period in subjects with type 2 diabetes.
