Question

which of the following is a rescue therapy asthma medication? singulair atrovent salmeterol nasalcrom

Explanation:

Rescue asthma medications are short - acting bronchodilators. Atrovent (ipratropium bromide) is a short - acting anticholinergic bronchodilator used for rescue therapy in asthma (and also in COPD). Singulair is a long - term control medication (leukotriene modifier), Salmeterol is a long - acting beta - agonist (used for control, not rescue), and Nasalcrom is a mast cell stabilizer used for prevention (not rescue).

Atrovent
