Transcript

  • 1. DRUGS FOR RESPIRATORY SYSTEM Ch 32, 33, 34
  • 2. INTRODUCTION (P. 283  Respiratory system provices mechanism for exchange of oxygen and carbon dioxide in the lungs  Upper Airway Nose Throat  trachea    Lower Airway trachea Bronchi  Lungs  Alveoli  
  • 3. DRUG CATEGORIES IN THIS UNIT Antihistamines  Decongestants  Antitussives  Mucolytics  Expectorants   Bronchodilators (sympathomimetics Corticosteroids  Leukotriene modifiers  Mast cell stabilizers  ☻
  • 4. DISORDERS  Common disorders of Respiratory System        Infections Allergic rhinitis Coughs Colds Congestion Asthma COPD
  • 5. URIS AND ALLERGIES Treated with OTC drugs if viral Treated with ABT if bacterial Also  Decongestants  Antitussives  Mucolytics  Expectorants
  • 6. LOWER RESPIRATORY AILMENTS treated with  Bronchodilators  Corticosteroids  Leukotriene modifiers  Mast cell stabilizers
  • 7. ANTITUSSIVES  Productuve Cough—secrretions are expelled  Non-productive –dry, hacking , no secretions  Atnitussive—relieves coughs  Action:  Depresses cough cneter in the medulla of the brain  Use:  relief of non-productive cough
  • 8. ANTITUSSIVES Adverse reactions (side effect)  Dizziness  Drowsiness  Sedation  GI Upset
  • 9. ANTITUSSIVES Precautions  Chronic cough  Excessive secretions  High fever  Opioids use caution as with other opioids  Avoid alcohol with codeine (additive effects)
  • 10. ANTITUSSIVE DRUG NAMES Codeine Benzonatate (Tessalon Perles) Dextromethorphan (Benylin, Robitussin, Delsym) Diphenhydramine (Benadryl)
  • 11. NURSING PROCESS Risk for injury r/t dizziness, sedation Ineffective airway clearance r/t pooling secretions
  • 12. NURSING PROCESS CON’T Document type of cough Description of sputum Check vital signs Observe therapeutic effects Provide for safety from falls Codeine may cause orthostatic hypotension
  • 13. NURSING PROCESS CON’T  Depression of cough reflex can lead to pooling of secretions  In turn, can lead to pneumonia, atelectasis  Encourage C&DB, Position change, fluids  Encourage patient to contact MD if cough persists > 10 days, fever, or chest pain
  • 14. MUCOLYTICS AND EXPECTORANTS  ACTIONS:   Mucolytic—breaks down thick tenacious mucus in lower airways Expectorant—increases respiratory secretions which in turn thins secretionsease of removal by coughing (raising ) the secretions
  • 15. MUCOLYTICS AND EXPECTORANTS  USE: Lower respiratory disorders  Acetaminophen (Tylenol) overdose   Adverse reactions Drowsiness  Sedation  GI upset   CI: Asthmatics
  • 16. MUCOLYTICS AND EXPECTORANTS Drug Names  Mucomyst (acetylcysteine)  guaifenesin (Robitussin, Mucines)
  • 17. NURSING PROCESS Ineffective airway clearance r/t thick mucus production Assess respiratory status Encourage fluids Take as directed
  • 18. ANTIHISTAMINES & DECONGESTANTS Histamine produced in response to allergic reaction or tissue injury Produces inflammatory response Drugs to treat (antihistamines)  Block the effects of histamine at the receptor sites
  • 19. ANTIHISTAMINES & DECONGESTANTS  Antihistamines  Action:  Block effects of histamine on H 1 receptors  Use: Allergies  Anaphylactic shock  Motion sickness  Adjunct to analgesia 
  • 20. ANTIHISTAMINES & DECONGESTANTS Side effects:  Drowsiness  Sedation  Dizziness  Dry mouth
  • 21. ANTIHISTAMINES & DECONGESTANTS Drug Names Antihistamines 1st generation ChlorTrimeton (chlorpheniramine)  Benadryl (diphenhydramine)  Phenergan ([romethazine ) 2nd generation Zyrtec (cetirizine) Allegra (fexofenadine) Claritin (loratidine) 
  • 22. ANTIHISTAMINES & DECONGESTANTS Precautions Glaucoma BPH Hypertension Kidney disease
  • 23. NURSING PROCESS  Impaired oral mucous membranesr/t dry mouth  Risk for injury r/t drowsiness  Teach no alcohol  No driving if drowsiness occurs  Take with food if GI upset  Empty stomach for Allegra
