Barriers to the use of prandial insulin regimens include inadequate synchronization of insulin action to postprandial plasma glucose excursions as well as a significant risk of hypoglycemia and weight gain. Technosphere® insulin (TI) is an inhaled ultra-rapid-acting human insulin that is quickly absorbed in the alveoli. With a time to maximum plasma drug concentration of approximately 14 min and a time to maximum effect of 35 to 40 min, TI more closely matches the postprandial insulin concentrations seen in nondiabetic individuals. Studies have shown that long-term administration of prandial TI in combination with long-acting basal insulin results in reductions in hemoglobin A1c comparable to conventional subcutaneously injected prandial insulins but with improved control of early postprandial BG. Furthermore, TI has been associated with less weight gain and a lower incidence of hypoglycemia, which may enhance patient satisfaction and acceptability of insulin therapy. This review discusses the clinical properties of TI and proposes strategies for optimal use.
使用餐时胰岛素方案的障碍包括胰岛素作用与餐后血糖波动的同步性不足,以及低血糖和体重增加的重大风险。Technosphere®胰岛素(TI)是一种吸入式超短效人胰岛素,可在肺泡中迅速吸收。TI的血浆药物浓度达峰值时间约为14分钟,最大效应时间为35至40分钟,与非糖尿病个体的餐后胰岛素浓度更接近。研究表明,餐时TI与长效基础胰岛素联合长期给药可使糖化血红蛋白降低,与传统皮下注射餐时胰岛素相当,但能更好地控制餐后早期血糖。此外,TI与体重增加较少和低血糖发生率较低有关,这可能会提高患者对胰岛素治疗的满意度和接受度。本综述讨论了TI的临床特性并提出了最佳使用策略。
