Last month, the US Food and Drug Administration announced that it had approved a new treatment for type 2 diabetes. The drug Januvia (sitagliptin phosphate) is the first in a new class of anti-diabetes medicines. It is reported to improve the body’s own ability of lower blood sugar that is too high. Januvia is used alone or in combination with certain diabetes medicines when diet and these other drugs alone do not provide adequate blood sugar control. The new drug seems to work in 2 different ways. One is to prolong the activity of certain proteins that causes the pancreas to produce more insulin, while also sending a signal to the liver indicating that it should stop producing glucose. According to some reports, Januvia causes few side effects, which may include diarrhea and sore throat. Type 2 diabetes is the most common type of diabetes, affecting 20 million Americans. This is a condition in which the body does not produce enough insulin to transport sugar to the cells, or body cells ignore the insulin that is produced. If blood sugar levels remain high for too long, the heart, kidneys, and nerves can be damaged.
