Ch 37 (test 9) Flashcards
Bronchodilators
given for asthma, chronic bronchitis, and emphysema. They dilate the bronchus and bronchioles that are narrowed. These drugs relax bronchial smooth muscle bands to dilate the bronchus and bronchioles.
Beta-Agonists
used during acute phase of an asthma attack to QUICKLY dilate airway constriction and restore airflow to normal.
3 beta-agonists
Albuterol (Proventil, Xoponex)
Serevent
Alupent
Anticholinergics
block acetylcoline receptors to PREVENT bronchoconstriction. DRYING. (not if peanut, legume, or soy allergy)
2 anticholinergics
Atrovent (ipratropium)
Spiriva
Xanthine derivatives
increase the levels of cAMP (less breakdown)
enhance respiratory drive in the medulla
slow action use to PREVENT mostly
stimulates CNS and Cardiac (avoid nicotine, charcoal, caffeine, high protein and low CHO diets.)
cAMP
necessary to maintain patent airways
inhibit release of histamines
2 xanthine derivatives
Aminophylline
Theophylline (slow-bid, Theo-dur)
For status asthmaticus
IV aminophylline if asthma does not respond to initial therapy.
Antileukotrine agents
newer class of respiratory drugs that prevent leukotrines form attaching to receptors in circulating immune cells; blocks inflammation in the lungs that occurs when the immune system is triggered by an allergen. PREVENTION in asthma
@ antileukotrines
Zyflo
Singulair
cortico-steroids
antiinflammatory drugs used for acute asthma attacks. PREVENT OR TREAT attacks. (cushing;’s and adison’s)
5 cortico-steroids
Azmacort (pulmacort) AeroBid Advair Flovent Solu-Medrol (IVP)
what to do when administering 2 inhalers
use bronchodilator first then steroid. wait 5 minutes between them.
