Viagra not only fights impotence but also reduces heart stress

VIAGRA not only fights impotence but also reduces the harmful effect of stress on the heart, scientists claimed yesterday.

Scientists tested the anti- impotence drug, sildenafil citrate, on 35 men and women who were given injections of an adrenaline-like chemical.

The chemical, dobutamine, mimics the effects of emotional or physical stress by increasing the force of heartbeats and boosting the flow of blood through the body.
