In the group of patients who adhered to their medication, those taking leukotriene modifiers-oral asthma controllers-were more likely to have an emergency room or inpatient physician visit, less likely to use six or more short-acting beta agonist canisters and incurred higher annual costs.
These categories include the following types of drugs: corticosteroids, beta-2 agonists, anticholinergic bronchodilators, methylxanthines, leukotriene modifiers, immunomodulators and mast cell stabilizers.
The Food and Drug Administration has called on manufacturers of leukotriene inhibitors to include safety precautions on their drugs' labeling, because of reports of neuropsychiatric events in patients taking these drugs.
