Zyflo is a prescription drug approved by the U.S. Food and Drug Administration (FDA) to treat asthma in adults and children 12 years of age and older. Zyflo is also referred to by its drug name, zileuton.
Zyflo is a member of a class of drugs called leukotriene inhibitors. Zyflo is believed to work by reducing the production of leukotrienes in the body. Leukotrienes are chemicals involved in airway edema (swelling), smooth muscle contraction, and other processes associated with the symptoms of asthma. Inhibiting (holding back) their production helps to relieve these symptoms.
