two new injectable diabetes drugs, Byetta (exenatide) and Symlin (pramlintide)

There's a lot of interest in two new injectable diabetes drugs, Byetta (exenatide) and Symlin (pramlintide).

These drugs are the first of their kind. They both mimic hormones that help regulate blood glucose.

Byetta is an incretin mimetic. It's the one that's based on a protein derived from Gila monster saliva.
