The Food and Drug Administration (FDA) has announced the approval of Cymbalta (duloxetine hydrochloride) capsules for the management of the pain associated with diabetic peripheral neuropathy. This is the first drug specifically approved for this indication. Cymbalta received a priority review.

"Diabetes affect millions of Americans," said Dr. Lester M. Crawford, Acting FDA Commissioner. "With this new treatment we will hopefully be able to help relieve the pain associated with this terrible disease."

Diabetic peripheral neuropathy is a problem associated with long standing diabetes or poor glucose control. Peripheral neuropathy is the most common complication of diabetes mellitus, affecting up to 62% of Americans with diabetes. Diabetic peripheral neuropathy can manifest in a variety of ways but is usually characterized by burning, tingling, and numbing sensations beginning in the feet, and later affecting the legs and/or hands.

The safety and effectiveness of Cymbalta were established in two randomized, controlled studies of approximately 1074 patients. Although the mechanism of action is unknown, patients treated with Cymbalta reported a greater decrease in pain compared to placebo. In these trials, 58 percent of patients treated with Cymbalta reported at least a 30 percent sustained reduction in pain. In comparison, 34 percent of patients treated with placebo reported this magnitude of sustained pain reduction.
