Some stroke patients in Prince Edward Island will be part of a global study aimed at improving stroke outcomes — by finding the best way to use a blood-clot-busting drug to help patients in emergency situations.

Health P.E.I. is contributing to the study, which is looking at the most effective dosage of Tenecteplase. The drug is already used on the Island.

“We’re trying to find out if a lower dose of this drug is safer but still does the good job of breaking up blood clots and rescuing a brain from a stroke,” said Dr. Heather Williams, a neurologist and the chair of Health P.E.I.’s stroke steering committee.

She said patients will be recruited for the study through emergency departments.
