Drugs and the respiratory system
The respiratory system, extending from the nose to the pulmonary capillaries, performs the essential function of gas exchange be-tween the body and its environment. In other words, it takes in oxygen and expels carbon dioxide.
Drugs used to improve respiratory symptoms are available in in-halation and systemic formulations. These drugs include:
§ beta2-adrenergic agonists
§ leukotriene modifiers
§ mast cell stabilizers
§ monoclonal antibodies
