FreeStyle Navigator CGMS Approved
March 14, 2008
A new continuous glucose monitoring system (CGMS), the Freestyle Navigator manufactured by Abbott Diabetes Care, has been approved by the U.S. Food and Drug Administration (FDA) for people with diabetes who are 18 and older.
Continuous glucose monitors are devices that help people track their glucose levels continually. While some details vary from system to system, all systems consist of a sensor worn under the skin that transmits information about the body’s glucose levels to a receiver. The receiver displays frequently updated glucose readings and stores information about changes in glucose levels over time. CGMS devices can also be programmed to set off alarms when glucose levels become too low or too high.
The FreeStyle Navigator, which was approved in Europe last June, has the following features.
According to a press release from Abbott, a study of 123 people using the Freestyle Navigator system at home found that people with Type 1 diabetes experienced less hypoglycemia (low blood glucose) and people with Type 2 diabetes experienced less hyperglycemia (high blood glucose) when using the system.
The Freestyle Navigator is projected to become available for purchase in the second quarter of this year; according to company representatives, the system will cost approximately $1,000, and a one-month supply of sensors (six per pack) will cost approximately $375. People can learn more about the system and begin the purchasing process (which includes getting a doctor’s prescription) at www.continuousmonitor.com.
Other continuous glucose monitors currently on the market are the Seven Continuous Glucose Monitoring System made by DexCom, the Guardian REAL-Time Continuous Glucose Monitoring System made by by Medtronic MiniMed, and the Paradigm REAL-Time Continuous Glucose Monitoring system, also from Medtronic MiniMed, in which the receiver is combined with an insulin pump.
