What is nitric oxide? Nitric oxide is a gas that is inhaled. It works by relaxing smooth muscle to widen (dilate) blood vessels, especially in the lungs. Nitric oxide is used together with a breathing machine (ventilator) to treat respiratory failure in premature babies. Your baby will receive this medication in a neonatal intensive care unit (NICU) or similar hospital setting.
The chemical, nitric oxide, signals blood vessels to open and close in response to the body's changing need for increased or decreased blood flow. Individuals with elevated cholesterol have an impaired ability to relax, or dilate, their blood vessels, which researchers attribute to a problem in nitric oxide activation. In individuals whose cholesterol levels were lowered by the drug fluvastatin, more nitric oxide was produced, improving dilation.
