Which of the following drugs are used in the treatment of asthma? (Select all that apply)
A. Salmeterol (long-acting beta2 agonist, LABA)
B. Fluticasone (inhaled corticosteroid, ICS)
C. Ipratropium bromide (anticholinergic)
D. Montelukast (leukotriene receptor antagonist)
Answer: ABCD
Explanation: Asthma treatment includes multiple drug classes: LABAs (e.g., salmeterol) for long-term bronchodilation, ICS (e.g., fluticasone) for anti-inflammatory control, anticholinergics (e.g., ipratropium) for bronchodilation, and leukotriene receptor antagonists (e.g., montelukast) for reducing inflammation and bronchoconstriction. All options are used in asthma management.
