The European commission has approved treating children Revatio (as Viagra is also sometimes called) for a rare, deadly lung condition. It was already used to treat adults with high blood pressure in the lungs, and now it can also be given to children aged 1 to 17. Pfizer (the drug company which sells it) is trying to get it approved in European countries.
The approval for these cases comes as a result of a study that was conducted, and which concluded that Viagra helped reduce arterial lung pressure in children, and was effective in treating PAH, helping the children breathe better and helping the lungs function better.
