A potentially life-saving drug could be on the way for people at risk of strokes which impacts around 27,000 Australians every year.

The Heart Research Institute has developed a drug called TBO-309 which has the potential to improve blood flow to the brain by busting clots and reducing the risk of brain injury caused by strokes.

It is the first breakthrough of its kind in more than 30 years and Australians will get their hands on the medication next month as part of a trial.
