About zileuton

Zileuton is a highly potent oral anti-inflammatory drug. It works by inhibiting
the enzyme 5-lipoxygenase. This enzyme, which is involved in the formation of
leukotrienes, is a key part of the inflammatory cascade that follows allergic
challenge. Inhibition of this enzyme therefore helps minimise
bronchoconstriction and mucus secretion in asthma. In its pivotal trials in
adult asthma, zileuton was shown to bring the greatest benefit to those with the
most severe disease. Zileuton is not intended for acute relief of asthma
symptoms but chronic treatment with zileuton allows reduction of other therapies
such as oral steroids which have undesirable side-effects.
