 It's a breakthrough in treating strokes. Reporter Scott Maimon has more on a new drug. Australian scientists have described the medication as a world breakthrough after their 25 years of research. This is the sort of therapy that could be used globally. Professor Sean Jackson says it's a new anti-blood clotting drug that works alongside existing stroke medication. It can be administered in the ambulance or as soon as the patient gets to the hospital. The drug makes a clot dissolve more effectively and lowers the risk of damage to the brain.
