• Breathlessness along with forcibleexhalation
• Cough
• Wheezingor whistling sounds whilebreathing
• Tightness of chest
• Thickmucussputum
• Aggravation of symptoms during the night and early morning
• Faintingafter severe respiratory distress or severe breathlessness
• Difficulty sleeping because of breathing problems
• Increased discomfort in lying position

It is best to identify the triggers to avoid and eliminate potential exposure. If avoidance of triggers is insufficient or not feasible, then medicine use is recommended. Currently, available important anti-asthma drugs can be classified as:

• 控制器(所需的维护treatment)
• Relievers (required for quick relief, rescue drugs)

Controllers (prophylactic, preventive, and maintenance)

Taken daily to keep asthma under control.

• Steroids
• Long-acting beta-2 agonists
• Sustained releasetheophylline
• Leukotriene receptor antagonists
• Cromones

Relievers (quick relief, rescue)

Rapid-acting drugs that relieve bronchoconstriction.

• Short-acting beta-2 agonists
• Anticholinergics
• Theophylline
• Short-course oral steroids
• For immediate treatment,bronchodilators(medications that widen the airways, such as beta-2 agonists) are used, which are usually administered by inhalation.
