New Medication May Prevent Brain Damage After Stroke

A new medication called NA-1 could be effective in reducing brain lesions and is being called safe to repair brain aneurysms in stroke patients after they have undergone surgery, according to researchers at the University of Calgary’s Hotchkiss Brain Institute in Canada. Study results appear in The Lancet Neurology.

At the beginning of their randomized, double-blind trial, the experts set out to determine whether NA-1 was safe. They then focused on how injections of NA-1 affected the number and volume of brain legions in stroke patients after surgery.

During the study, the researchers administered 185 patients who had just undergone surgery with either an intravenous infusion of NA-1 or saline control; 92 patients received the NA-1 drug, while 93 participants were given a placebo. Over the next three days, the team performed MRIs on the patients to evaluate the degree of stroke legions present. To determine the results, the participants were followed up on 30 days later.
