UPDATED ACTUAL Questions and CORRECT Answers
1. What are examples of inhaled Short-acting Albuterol and levabuterol
Beta Agonists? (SABAs)
2. What is the MOA of inhaled beta agonists? To relax airway smooth muscle by increasing
cyclic cAMP; dilation and opening of airway
3. What is the use of inhaled beta agonists? Used in bronchospasm associated with:
asthma, bronchitis, and COPD
4. When are SABAs used (albuterol and lev- For relief of ACUTE asthma attacks
abuterol)?
5. Is albuterol approved in children under 4? Yes.
6. How do beta-2 agonists affect calcium? They open large conductions in calcium acti-
vated potassium channels = hyperpolarized
airway smooth muscle cells
1. decreased intracellular calcium
2. increased potassium concentration
3. decreased myocleynase activity = smooth
muscle relaxation and bronchodilation
7. What are examples of long-acting beta ag- salmetrol and formoterol
onists (LABAs)?
8. What are LABAs (salmeterol and for- Used for PREVENTION or long term treat-
moterol) used for? ment of asthma
NOT for acute attacks; not first line treat-
ment
CANNOT be used alone

prescribed in?
10. What is special about the beta 2 adrener- This gene causes LABAs to worsen asthma
gic receptor gene? control
11. Who is more likely to have the beta 2 African Americans; this genotype is present
adrenergic receptor gene? in 1/6th of the U.S. population
12. How does the beta 2 adrenergic recep- Asthmatics with this gene are at risk for de-
tor gene cause worsening asthma control creased airflow and worsening asthma con-
when LABAs are taken? trol
13. What are adverse effects of inhaled beta Tachycardia and tremors
agonists?
14. What is the absorption of inhaled beta ag- Very little systemic absorption
onists?
15. What are examples of anticholinergics/an- ipatroprium (Atrovent) and tiotroprium
timuscarinics in maintenance therapy of (Spiriva)
COPD?
16. What is the MOA of anticholinergics (ipat- They block muscarinic receptors decreasing
roprium and tiotroprium)? the formation of cAMP
CAUSES BRONCHODILATION BY:
1. decreasing smooth muscle contraction of
lungs (mainly on M3 receptors)
2. decreases mucous secretion
17. What are ipatroprium and tiotroprium Maintenance of COPD
used for?

18. What is tiotroprium (Spiriva)? LONG-ACTING bronchodilator for COPD;
better absorbed from lung than ipatroprium
(Atrovent)
19. What is ipotroprium (Atrovent)? SHORT-ACTING bronchodilator for COPD
20. What bronchodilator is the best choice in Ipatroprium (Atrovent)
patients taking propranolol?
21. What are the adverse effects of ipatropri- Anticholinergic -- can't see, can't pee, can't
um and tiotroprium? spit, can't shit
22. What are examples of inhaled corticos- fluticasone (Flonase), budesonide (Pul-
teroids? micort), beclomethasone diproprionate
(QVAR)
23. What are inhaled corticosteroids used for? Long-term treatment of asthma (severe,
persistent asthma); taken everyday
24. What is the absorption of inhaled corticos- Rapid absorption from lung tissues; greater
teroids? with use of spacer
25. What effects do inhaled corticosteroids Anti-inflammatory and vasoconstrictor ef-
have? fects
Highly selective agonists at the glucocorti-
coid receptor and some activity at androgen,
estrogen, and corticoid receptors
26. What is the MOA of inhaled corticos- INHIBITS mast cell migration to bronchial
teroids? tissues
27. What is the bioavailability of inhaled corti-
costeroids?
