True about zafirlukast is :
assistant
The correct answer is  Zafirlukast and montelukast are cysteinyl leukotriene receptor antagonists. They cause modest improvement in lung function and reduction in asthma symptoms and lessen the need for beta-agonist rescue therapy. These drugs can be considered as alternatives to low-dose inhaled corticosteroids in patients with persistent asthma.
Zafirlukast is long-acting and can be given twice to once daily orally. It is a modest bronchodilator that reduces asthma morbidity, provides protection against exercise-induced asthma and diminishes nocturnal symptoms.
These are less effective than corticosteroids.
