Final answer:
Nonsteroidal antiasthma drugs work by inhibiting inflammatory molecules or the receptors for inflammatory molecules. They open up the airways wider and alleviate the symptoms of asthma attacks.
Step-by-step explanation:
Nonsteroidal antiasthma drugs work by inhibiting inflammatory molecules or the receptors for inflammatory molecules. They are a type of medication used to treat asthma by opening up the airways wider, making it easier to breathe. These drugs, such as ibuprofen and aspirin, obstruct the synthesis of prostaglandins by inhibiting the enzyme cyclooxygenase, which is needed for the conversion of arachidonic acid to prostaglandins. By reducing inflammation in the airway passages, nonsteroidal antiasthma drugs help alleviate the symptoms of asthma attacks.
