FlexTouch: A Prefilled Insulin Pen with a Novel Injection Mechanism with Consistent High Accuracy at Low- (1 U), Medium- (40 U), and High- (80 U) Dose Settings

摘要

Background: FlexTouch? is the only prefilled insulin pen that utilizes an easy touch button that does not extend at any dose in place of a push-button extension. Rigorous testing has shown that the new FlexTouch pen accurately and consistently delivers insulin doses. Methods: This study assessed dose accuracy of FlexTouch, KwikPen?, and SoloSTAR?. Dose accuracy for minimum, medium, and maximum doses of each pen type (1, 40, and 80 U for FlexTouch and SoloSTAR and 1, 30, and 60 U for KwikPen) was assessed. Results: FlexTouch delivered all doses consistently, as demonstrated by low standard deviations. FlexTouch showed similar accuracy to KwikPen at 1 U and to SoloSTAR at 40 and 80 U. However, FlexTouch was significantly more accurate at delivering 1 U of insulin than SoloSTAR ( p < .0001). Conclusions: This study demonstrates that FlexTouch, a new prefilled pen, delivers insulin accurately and consistently at low, medium, and high doses. In addition, FlexTouch is currently the only prefilled pen that has a push button that does not extend at any dose, making FlexTouch easier to use than other pens.
