Respiratory Agents

  1. Purpose of antihistamines
    to treat symptoms of rhinitis,prevent motion sickness,induce sleep, suppress the cough response
  2. Purpose of decongestants
    to relieve nasal congestion
  3. Purpose of antitussives
    to suppress non-productive cough
  4. action of antitussive
    act on cough control center in medulla to suppress the cough reflex
  5. S/E of antitussive
    drowsiness, dizziness, nausea,constipation
  6. A/R of antitussives
    hallucinations at high doses
  7. action of antihistamines
    blocks histamines thereby decreasing allergic response
  8. S/E of antihistamines
    drowsiness,dry mouth,urinary retention,constipation,photosensitivity
  9. A/R of antihistamines
    hemolytic anemia, thrombocytopenia
  10. action of decongestant
    stimulate alpha-adrenergic receptors ->capillary vasoconstriction ->decreases secretions and shrinks nasal mucous membanes
  11. S/E of decongestant
    jittery, nervous, hypertension
  12. A/R of decongestant
    frequent use equals tolerance and rebound, ^ bp and blood glucose levels
  13. action of expectorant
    increase production of respiratory tract fluids to help liquefy and decrease viscosity of secretions
  14. purpose of expectorant
    to loosen and promote elimination of bronchial secretions
  15. S/E of expectorant
    dizziness, nausea, vomiting ,rash
  16. purpose of sympathomimetic brochodilators
    to treat bronchospasms associated with acute asthma attacks
  17. action of sympathomimetic brochodilators
    relaxing of smooth muscle of bronchi
  18. S/E of sympathomimetic brochodilators
    nervousness, tremors, restlessness, insomnia, hyperglycemia, muscle cramps
  19. A/R of sympathomimetic brochodilators
    tachycardia, palpitations, hypertension
  20. purpose of methylxanthine bronchodilators
    to promote bronchodilation in asthma and chronic obstructive pulmonary disease(COPD)
  21. action of methylxanthine bronchodilators
    relaxation of smooth muscle of bronchi ->bronchodilation
  22. S/E of methylxanthine bronchodilators
    annorexia, nausea, vomiting
  23. A/R of methylxanthine bronchodilators
    cardiac dysrythmia, tachycardia, seizures
  24. purpose of mast cell stabilizer
    prophylactic treatment of bronchial asthma and allergic rhinitis
  25. action of mast cell stabilizer
    inhibits release of hestamine from mast cells
  26. S/E of mast cell stabilizer
    rebound bronchoconstriction cough
  27. A/R of mast cell stabilizer
  28. purpose of leukotriene receptor antagonists
    to reduce inflammatory symptoms of asthma triggered by allergic and environmental stimuli
  29. action of leukotriene receptor antagonists
    inhibits leukotriene formation,mucous production and airway wall edema
  30. S/E of leukotriene receptor antagonists
    fever, fatigue, nasal congestion, cough, sore throat, dental pain, rash
  31. A/R of leukotriene receptor antagonists
