Comparing the Effects of Insulin Glargine on Blood Glucose Between Needle-free Jet Injection and Insulin Pen

Study Overview
=================
Brief Summary
-----------------
To comparing the blood sugar improvement and patient sensibility of insulin glargine injected with needle-free jet injector and conventional insulin pen

Detailed Description
-----------------
Compared with conventional pen, needle-free jet injection of insulin has faster flow rate and larger area of local subcutaneous absorption. The aim of this study was to investigate the effects of subcutaneous insulin glargine injection with needle-free jet injection and conventional pen on blood glucose profile and safety in type 2 diabetic patients.
