Drug ‘may prevent stroke damage’

It may be possible to use a drug to prevent some of the lasting and crippling damage caused by a stroke, according to doctors in the US and Canada.

A safety trial, published in the Lancet medical journal, suggested the chemical NA-1 was safe to use.

The study on 185 people also hinted that patients given the drug developed fewer regions of damaged brain tissue.

The Stroke Association said that it was promising, but needed more research.

Tests in primates had suggested NA-1 prevented brain cells dying when a stroke starved them of oxygen.

A small trial was set up at 14 hospitals in the US and Canada.

Patients who took part were having an operation to repair a brain aneurysm, a weakened blood vessel which could rupture, are at increased risk of a stroke.

Ninety-two people had the drug injected into a vein, while another 93 were injected with salty water.

The doctors concluded that NA-1 was safe, with only two patients having mild side effects.

However, brain scans also showed that fewer brain lesions, damaged areas of tissue, formed in patients given the drug.
