Study Notes
Inhaled Corticosteroids
- Most effective long-term control medication for asthma
- Reduce inflammation and swelling in airways
- Examples:
- Fluticasone (Flovent)
- Budesonide (Pulmicort)
- Triamcinolone (Azmacort)
- Dose-dependent side effects:
- Oropharyngeal candidiasis
- Dysphonia
- Adrenal suppression (high doses)
Leukotriene Modifiers
- Inhibit production of leukotrienes, which cause airway constriction and inflammation
- Examples:
- Montelukast (Singulair)
- Zafirlukast (Accolate)
- Indications:
- Mild to moderate asthma
- Exercise-induced bronchospasm
- Side effects:
- Headache
- Gastrointestinal disturbances
- Churg-Strauss syndrome (rare)
Pharmacogenetics
- Study of genetic variation affecting response to asthma medications
- Genetic polymorphisms influencing response to:
- Beta2-agonists
- Corticosteroids
- Leukotriene modifiers
- Implications:
- Personalized medicine
- Tailored treatment approaches
- Improved treatment outcomes
Bronchodilators
- Quick-relief medications for acute asthma symptoms
- Types:
- Beta2-agonists:
- Short-acting (SABA): Albuterol (Ventolin)
- Long-acting (LABA): Salmeterol (Serevent)
- Anticholinergics:
- Ipratropium (Atrovent)
- Beta2-agonists:
- Mechanism:
- Relax airway smooth muscle
- Increase airflow
- Side effects:
- Tremors
- Anxiety
- Tachycardia
Mast Cell Stabilizers
- Prevent mast cell degranulation, reducing bronchospasm and inflammation
- Examples:
- Cromolyn sodium (Intal)
- Nedocromil (Tilade)
- Indications:
- Mild to moderate asthma
- Exercise-induced bronchospasm
- Side effects:
- Cough
- Bad taste
- Gastrointestinal disturbances
