leukotriene receptor antagonist
Definition: a class of agents, of which zileuton, montelukast, zafirlukast are the best known, used in the prophylactic and chronic treatment of asthma in older children and adults; these drugs are not bronchodilators in themselves, but act by interfering with the leukotriene-mediated inflammatory process present in asthma.
