Respiratory drugs (COPD (symptoms (progressive shortness of breath,…

- - - - oxygenation is decreased
- - - - work by inhibiting release of inflammatory substances which decreases inflammation
    - - adverse effects
        
        hoarsness, cough, oral candidiasis, rinse mouth after each use
  - - - used in combination with ICS for asthmas patients
        
        salmeterol/fluticasone work by stimulating B2 receptors which results in bronchodilation
    - - dry mouth, bitter taste
  - - - first line treatment for COPD, works by inhibiting ACh receptors on smooth muscle which results in bronchodilation
    - - dry mouth, bitter taste
  - - - oral tablets that may be used as adjuncts to ICS in asthma work bu inhibiting the activity of leukotrienes
    - - muscle aches, headaches, heartburn, nausea
- - - - t-lymphocytes, eosinophils, mast cells
        
        these result in inflammation and edema which leads to bronchoconstriction of smooth muscle
        
        airway obstructin occurs due to increased mucus production as well as edema
        
        airway obstruction> increased work to breathe; cough wheezing
- - - - work by stimulating Beta 2 receptors which results in bronchodilation
    - - nervouseness, dry mouth, throat irritation, fast heartbeat
  - - - used in combination with beta 2 agonists or patients who cant tolerate B2 agonists,
        work by inhibiting ACh receptors on smooth muscle which results in bronchodilation
    - - dry mouth, bitter taste
  - - - acute asthma attacks, especially in emergency settings
        
        works by inhibiting inflammatory process
    - - hyperglycemia, fluid retention, low potassium, increased appetite, growth suppression
- - - - 1st generation
        
        benadryl, works by blocking H1 receptors
        
        adverse effects include drowsiness, dry mouth, blurred vision, urinary retention
      - 2nd generation
        
        zyrtec, works by inhibiting H1 receptors
    - - nasonex works by relieving symptoms of itching, sneezing, congestion and runny nose
      - adverse effects include nasal irritation, burning, sneezing, sore throat
    - - adverse effects include nervousness, tremor, insomnia, dizziness, chronic mucosal inflammation
      - Pseudoephedrine, works by stimulating a1 adrenergic receptors which causes vasoconstriction of nasal mucosa available OTC
