Treatment Summary
Zileuton is a medication that helps reduce the symptoms of asthma. It works by blocking the formation of certain substances called leukotrienes, which cause inflammation, swelling, increased mucus production, and constriction of the airways in asthmatic patients. The drug is specifically designed to inhibit the enzyme 5-lipoxygenase, which is responsible for forming leukotrienes from arachidonic acid. Zileuton was previously available as an immediate release tablet in the US, but has since been withdrawn from the market.

How Zyflo Affects Patients
Zileuton is a drug used to treat asthma. It works by blocking the leukotriene synthesis pathway, which is thought to contribute to asthma symptoms. It has been shown to reduce asthma symptoms caused by cold air in humans.
How Zyflo works in the body
Zileuton helps relieve symptoms of asthma by blocking the production of substances called leukotrienes. Leukotrienes cause inflammation and narrowing of the airways in asthmatic patients. Zileuton specifically targets 5-lipoxygenase, an enzyme that makes leukotrienes. By blocking the formation of these substances, Zileuton helps reduce inflammation, bronchial spasms, and other asthma symptoms. Both the R(+) and S(-) enantiomers of the drug have been shown to be effective in laboratory studies.
