Fenoterol asthma treatment

Bronchodilation. P2-Adrenocep-tor-mediated bronchodilation (e.g., with terbutaline, fenoterol, or salbutamol) plays an essential part in the treatment of bronchial asthma (p. 328). 

Fenoterol (200 to 400 meg by inhalation), a beta2-adrenergic receptor agonist, is being used in patients with moderate to severe asthma, with chronic obstructive pulmonary disease, in protection against exercise-induced asthma, and for acute treatment of asthma attack. However, no apparent advantage of fenoterol over equipotent doses of albuterol or terbutaline has been demonstrated in clinical trials (see also Figure 94).
