Commercially available CGM systems
Development of insulin formulations and routes of delivery with more favorable pk characteristics
-
Both, real-time CGM (rtCGM) and intermittently scanned CGM (isCGM) continuously monitor interstitial glucose levels and transmit the data in numerical and graphical formats to the user’s handheld reader or a smartphone app
-
rtCGM devices: Automatically transmit the data to the reader or smartphone
-
isCGM devices: Users must manually scan the sensor with their reader or smartphone to transfer data
-
Most of these CGM devices have programmable alarms to warn patients when current or predicted glucose levels are outside their individualized target ranges
-
All the systems can transmit retrospective glucose data via web-based cloud-access sites or dedicated download software programs, to the patient’s clinician and help in comprehensive analysis and interpretation
