Case: agents used to treat asthma. Class

Asthma is characterized by acute episodes of bronchoconstriction caused by underlying airway inflammation.

Asthma typically occurs with both an early-phase response lasting approximately 1-2 hours that is triggered by autocoids and inflammatory mediators such as histamine, leukotrienes, and prostaglandins.
