DIABETES NEWS: A common over-the-counter cough suppressant can boost insulin: Type 2 diabetics could benefit from a drug that’s already on the market. “Results in mouse cells, human cells, and mouse models of type 2 diabetes were so promising that the researchers were able to perform a registered phase 2a double-blinded, placebo-controlled, randomized study on twenty men with type 2 diabetes. The real deal. Participants were all already taking metformin, an antidiabetes drug that inhibits the synthesis of glucose in the liver. Results were consistent with those seen in tissue culture and animal studies: DXM increased islet cell viability, glucose-stimulated insulin secretion, and glucose tolerance—all without eliciting hypoglycemia. Remember, this is an over the counter cough suppressant we’re talking about here.”
