Which of the following drugs is a leukotriene receptor antagonist?
a. montelukast (Singulair)
b. cromolyn sodium (Intal)
c. triamcinolone (Azmacort)
d. theophylline (TheoDur)
a. Leukotrine modifiers are orally administered agents that also may be alternative first-line treatment for mild persistent asthma and may serve as adjuncts to inhaled corticosteroids for more severe disease. These agents block the synthesis of arachidonic acid derivatives (e.g., leukotrienes), which are involved in the inflammatory pathway. Montelukast (Singulair) is the most prescribed because of its once-a-day dosing. These drugs reduce the need for short-acting, inhaled b2-agonists.
