Dextromethorphan, sold in Canada as an ingredient of the over-the-counter cough medicine Robitussin and Bronchophan Forte DM, could help in regulating type 2 diabetes according to a new study.

In mice, this medicine was found to improve glucose control, while in a small human clinical trial (20 men with Type 2 diabetes) the researchers found it increased insulin and lowered blood glucose.

Researchers conclude that dextromethorphan could become a useful adjunct treatment for diabetes.
