Beta-2 agonists — role?
Relax airway smooth muscle for bronchodilation.
Corticosteroids — mechanism?
Inhibit inflammatory gene expression.
Leukotriene modifiers — use?
Reduce airway inflammation in asthma.
Asthma — key features?
Chronic airway inflammation, hyperresponsiveness, wheezing.
COPD — primary cause?
Smoking-induced airway inflammation and alveolar destruction.
Bronchodilators — role?
Relax airway muscles, relieve airflow obstruction.
Anti-inflammatory agents — purpose?
Reduce airway inflammation, prevent exacerbations.
Inhaled corticosteroids — use?
Control persistent asthma, reduce airway inflammation.
Leukotriene modifiers — target?
Block leukotrienes, asthma inflammation mediators.
Beta-2 agonists — example?
Albuterol (short-acting), salmeterol (long-acting).
