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.
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.
