Leukotriene modifiers

There are two types of agents that modify leukotriene response: inhibitors of LT synthesis that block lipo-oxygenase, and LTreceptor antagonists. The drugs zafirlukast and

In theory, these LTmodifying agents could have a major role in the treatment of asthma. Howevertheory and practice are not identical; many asthmatics appear not to have anybenefit from LT modifiers, which now are prescribed mainly for mild asthma orasthma with profound exercise-induced symptoms.
