Chest x-ray reveals increased anteroposterior diameter. Past medical history is significant for multiple episodes of bronchitis as a child. Which of the following drugs would be most effective for long-term treatment of this patient?? A: Albuterol, B: Fluticasone, C: Theophylline, D: Ipratroprium, E: Zileuton,  <response>: This is a patient with symptoms and findings consistent with asthma, including dyspnea, nocturnal cough, wheezing on expiration, and increased anteroposterior diameter on chest x-ray. The history of recurrent bronchitis as a child also supports a diagnosis of asthma.

Zileuton is a leukotriene inhibitor that can be used as adjunctive therapy but is not the most effective long-term monotherapy.B: Fluticasone
