The findings could point to yet another use for the medicine, which was first developed as a heart medication until researchers noticed that it helped impotent men have erections. This time, researchers stumbled upon an alternate use while using a Viagra-like drug to treat a rare condition that causes high blood pressure in the arteries that lead to the lungs.
