In case of a small group, 4-6% of stoke patients suffer from fatal hemorrhage after the treatment with the activase drug. But when the dug is properly administered it brings back normalcy in case of the stroke patient. Research is going on to find new drugs that work beyond the three-hour window period.
The various drugs that are in the pipeline are Desmoteplase, anti clotting substance that is being tested whether it can be used after the three-hour window period. Factor VII a clotting agent exclusively to treat hemorrhagic stroke. Cerovive an anti-inflammatory drug to prevent the killing of the nerve cells after a stroke.
Activase coupled with ultrasound is also very effective at dissolving clots. Magnetic resonance images (MRIs) can also be used to identify those patients who can be brought back to normalcy after the three-hour window period.
