Diabetes Drug Could Be a Promising Therapy for Traumatic Brain Injury

In continuation of my update on Exendin-4
Research commissioned by the United States Air Force, Prof. Chaim Pick of Tel Aviv University's Sackler Faculty of Medicine and Dr. Nigel Greig of the National Institute of Aging in the US have discovered that Exendin-4, an FDA-approved diabetes drug, significantly minimizes damage in TBI animal models when administered shortly after the initial incident. Originally designed to control sugar levels in the body, the drug has recently been found effective in protecting neurons in disorders such as Alzheimer's disease.
Prof. Pick's collaborators include his TAU colleagues Dr. Vardit Rubovitch, Lital Rachmany-Raber, and Prof. Shaul Schreiber, and Dr. David Tweedie of the National Institute of Aging in the US. Detailed in the journal Experimental Neurology, this breakthrough is the first step towards developing a cocktail of medications to prevent as much brain damage as possible following injury....

Exenatide for weight reduction !...

Exenatide, ( 39-amino-acid peptide an insulin secreta gogue with glucoregulatory effects) a compound belonging to "incretin mimetics" was approved for the treatment of diabetes mellitus type 2 in April, 2005, but not for type 1.

Exenatide is a synthetic version of exendin-4, a hormone found in the saliva of the Gila monster. It displays biological properties similar to human glucagon-like peptide-1 (GLP-1), a regulator of glucose metabolism and insulin secretion. According to the package insert, exenatide enhances glucose-dependent insulin secretion by the pancreatic beta-cell, suppresses inappropriately elevated glucagon secretion, and slows gastric emptying, although the mechanism of action is still under study.
Recently it has been found that along with the treatment for type 2, the compound has been found to reduce the weight of non diabetic obese people.
Michael Trautmann, MD, a Principal Investigator with Eli Lilly in Indianapolis, recently reported that in combination with diet and exercise, the diabetes drug exenatide helped nondiabetic, obese individuals lose over three times more weight than those receiving a placebo, or dummy treatment, for 6 months. Drug therapy is considered important adjunctive treatment to diet and exercise in the successful management of obesity, Trautmann said. "To date, however, there are few effective drugs that help obese people lose weight", which is very important fact. and as the drug is already an established one, the only side effect like mild or moderate nausea and diarrhea are to be taken care off.
As per the claims of the authors : individuals who received exenatide lost more weight in 24 weeks than controls did. Those who received the medication lost an average of more than 11 pounds (5.06 kg), whereas the controls lost just 3.5 pounds (1.61 kg). This difference was statistically significant and noted as early as week 8. Only exenatide-treated subjects lost more than 10 percent of their body weight (seven of 73 subjects, or 9.6%). The plausible explaination for the action of this drug is "decreased food intake and increased feelings of fullness".
