Dimenhydrinate
1st generation antihistamine: Reversible inhibitor of H1 histamine receptors
Albuterol

Bitolterol
Short-acting beta-2 agonist
Salmeterol
Long-acting beta-2 agonist
Ambrisentan
Competitive antagonist of endothelin-1 receptors - decreases pulmonary vascular resistance
N-acetylcysteine
Mucolytic - liqufies mucus in chronic bronchopulmonary diseases (e.g., COPD, CF) by disrupting disulfide bonds
