London, Oct 27 : Viagra can overcome the signalling defect and relieve exercise-induced fatigue associated with muscular dystrophies, according to a new study.

In the study on mice, researchers at University of Iowa showed that Viagra could alleviate fatigue in the animals with mislocalized enzyme called neuronal nitric oxide synthase (nNOS).

They also showed that there was a difference between the prolonged fatigue after mild exercise in muscular dystrophy patients and the inherent muscle weakness caused by the disease.

The researchers identified a faulty signalling pathway that apparently leads to exercise-induced fatigue in mouse models of muscular dystrophy.
