2. Know the difference between short and long term treatments for asthma and COPD
a. Short term asthma treatment:
i. Bronchodilator: albuterol
1. Acts as a rescue inhaler during asthma attacks.
2. Onset is in 5 minutes and will last longer.
ii. Xanthine Derivatives: theophylline
1. Dilates airways
2. Can have high drug interactions in the body
iii. IV/ inhaled glucocorticoids.
, b. Long term asthma treatment:
i. Bronchodilator: salmeterol.
1. Used to control symptoms of asthma
2. Never is used alone (often with steroid)
ii. Anticholinergics: ipratropium bromide
1. For long term asthma prevention
2. Works very slowly.
3. Fast onset, short duration
* Tiotropium has longer duration that Ipratropium
iii. Corticosteroids: fluticasone or Budesonide
1. Non bronchodilation
2. Can take several weeks to show
c. COPD treatment:
i. Bronchodilator- short acting albuterol
ii. Steroid
iii. Must keep o2 saturation between 88-92%
3. Know classifications for respiratory drugs (what’s used as a rescue inhaler, and what
is for long term management)
a. Rescue inhalers: albuterol, epinephrine, metaproterenol, IV steroid
b. Long term: salmeterol, ipratropium, theophylline, montelukast ,fluticasone
4. Treatment of acute asthma
a. Oxygen use
b. Short acting bronchodilator- albuterol
c. Corticosteroid- ipratropium bromide IV
d. Will relieve hypoxemia, reduce airway inflammation, and relieve obstruction.
5. Administration of bronchodilator (MOA,SE,Considerations)
a. MOA: mimics the sympathetic NS and opens up the lungs and stimulates beta receptors
b. Fast acting: used for acute asthma relief, Long acting is for chronic asthma
management and COPD
c. AE: tachycardia, angina, tremors, nervous and shaky feeling, hyperglycemia.
d. Considerations: ensure patient takes medication as prescribed and does not
overuse short acting bronchodilator. Never use it alone with asthma treatment.
6. Administration of glucocorticoids (IV vs inhaled, nursing interventions, pt. education)
a. MOA: works to stop the inflammatory process in the lungs, preventing
bronchoconstriction. Stabilizes WBC membranes that release bronchial constricting
substances, increases bronchial smooth muscle beta adrenergic stimulation.
b. Inhaled: used for asthma and is the most tolerated and fast acting, but can also
be IV for systemic effects on the body.
c. AE: throat and mouth irritation, dry mouth, oral fungal infections.
d. Must be used with another drug for asthma control.
e. Nursing interventions: must teach patients to rinse mouth out after steroid use
to prevent oral fungal infections, take bronchodilator 5 mins before steroid.
7. Tiotropium administration, onset, and therapeutic level timeframes
