Other Respiratory AgentsLilley Pharmacology
Text Chapter 35
  • Original Text modified by
  • Anita A. Kovalsky, R.N., M.N.Ed.,
  • Professor of Nursing
  • Original PPT by
  • Professor Pat Woodbery, ARNP, CS

2
Overview of Drugs Affecting the Respiratory
System
  • Bronchodilators
  • Xanthine derivatives
  • Beta-agonists (Adrenergics)
  • Anticholinergics
  • Antileukotriene agents
  • Corticosteroids
  • Mast cell stabilizers

3
AnticholinergicsBlock the action of
acetylcholine in bronchial smooth
muscle?preventing bronchoconstriction and causing
airways to dilate
  • Prototype Drug Anticholinergic (Brand name in
    parentheses) (Refer to Prototype List in
    syllabus Also listed in Lilley, pg. 550)
  • Ipratropium bromide (Atrovent)

4
Antileukotreines Prevent leukotreines from
attaching to receptors on cells in the lungs and
circulation
  • Prototype Drug Antileukotreines (Brand name in
    parentheses) (Refer to Prototype List in
    syllabus Also listed in Lilley, pg.
    552)Zafirlukast (Accolate)

5
Corticosteroids Purpose of Endogenous
  • Metabolic
  • Inflammatory
  • Immune processes
  • Fluid and Electrolyte Balance

6
Corticosteroids Desired Effect of Exogenous
Preparations
  • Anti-inflammatory
  • Immunosuppressive
  • Anti-allergic
  • Anti-stress

7
Disorders treated with Exogenous Corticosteroids
  • Allergic
  • Respiratory
  • Dermatological
  • Endocrine
  • Neoplastic

8
CorticosteroidsMechanism of ActionRefer to
Lilley pg. 553, Table 35-4
  • Suppress leukoctyes (WBCs)? thereby reducing
    inflammation and causing bronchodilation
  • Increase responsiveness of bronchiole smooth
    muscle to beta-adrenergic receptor stimulation
    (this produces an enhanced effect to
    beta-agonists)

9
Corticosteroids
  • Prototype Drug Corticosteroids (Brand name in
    parentheses) (Refer to Prototype List in
    syllabus Also listed in Lilley, pg.
    555)Beclomethasone (Vanceril)
  • Methylprednisolone (Medrol)

10
Nursing Assessment
  • History of Steroid Use gt2 weeks
  • Time Frame
  • Dosage
  • Rationale for taking
  • Infection Present
  • GI Problems
  • Skin or Bone Problems

11
Corticosteroids
  • More than 2 weeks of steroid use results in
    higher risk of long term effects of steroid usage
  • Persons taking systemic steroids are at higher
    risk for infection, GI problems (GI bleed), and
    osteoporosis.
  • A complete list of side effects is on page 488,
    Table 31-4

12
Long Term Use of Corticosteroids
  • Dont Stop Abruptly
  • Avoid Infected People and Places
  • Avoid Falls
  • Watch for Weight Gain
  • Take with Food

13
Mast Cell Stabilizers Prevent the release of
bronchoconstrictive and inflammatory
substancesNo direct bronchodilating
effectUsed for PREVENTION of attacks caused by
allergens and exercise
  • Prototype Drug Mast Cell Stabilizers (Brand
    name in parentheses) (Refer to Prototype List in
    syllabus Also listed in Lilley, pg.
    557)Cromolyn (Intal)

14
Administering Medications Via Metered-Dose
InhalersRefer to Lilley, pp.114-115
  • Preparation
  • Administration (optional use of spacers
  • Documentation
  • Precautions!!!!!
  • Client teaching!!!!!

15
Patient Teaching for Other Respiratory Agents
  • Assess for other chronic illnesses
  • Inhaled bronchodilators work fast, others work
    more slowly
  • Take bronchodilators FIRST!
