Q

what are the 2 subcategories of beta 2 adrenergic agonists? which of those is considered a “rescue med?” and which is a “maintenance med?”

A

LABA (long acting) + SABA (short acting)

24
Q

describe what the transition from oral to inhaled glucocorticoids would look like, and why?

A

done SLOWLY. meds must overlap.

to avoid adrenal insufficiency

25
Q

re: oxygenation, what is the prototype for LEUKotriene modifier

A

monteLUKast (Singulair)

26
Q

MOA for monteLUKast

A

blocks inflammation –> less edema, inflammation, bronchoconstriction

27
Q

what is monteLUKast used for?

29
Q

what is omalizumab used for? and when is it used?

A

allergy-related asthma (severe, persistent)

used when high dose steroids haven’t worked (last resort)

30
Q

what is the severe SE of omalizumab?

what are standards for observation after this drug is administered?

A

anaphylaxis

observe 2 hours after 1st dose 3x, then 30 mins q dose after

31
Q

describe route and frequency of omalizumab admin

A

Subcutaneous q 2-4 weeks

32
Q

re: oxygenation, what is the prototype for phosphodiesterase type 4 (PDE4) inhibitor?

A

roflumilast

33
Q

when would we use phosphodiesterase inhibitor? what is the prototype?

A

severe COPD w/chronic bronchitis (END STAGE)

roflumiLAST

34

psychiatric effects :(

35
Q

allergic rhinitis drugs can be broken down into which 2 categories?

A

preventers + relievers

36
Q

prototype for 1st generation antihistamine

A

diphenhydramine (Benadryl)

37
Q

prototype for 2nd generation antihistamine

A

loratidine (Claritin)

38
Q

antihistamines work BEST if taken ______?

A

prophylactically

-with loratidine, ideally, several weeks before allergies start kicking in

39
Q

between 1st and 2nd generation antihistamines, which produce LESS sedation? what is the prototype for that one?

A

2nd gen - loratidine (Claritin)

40
Q

which drug is MOST effective for seasonal allergies?

A

fluticasone (Flonase)

41
Q

re: allergic rhinitis, what is the prototype for intranasal glucocorticoids?

A

fluticasone

42
Q

SE of fluticasone

A

specific to nasal passages: burning, drying, epistaxis

43
Q

tips / tricks to avoid SE of fluticasone

A

nose to toes, avoid placing tip near septum, GENTLY sniff in

44
Q

re: allergic rhinitis, another name for sympathomimetics is what?

A

decongestants

45
Q

prototype for PO decongestant

A

pseudoephedrine (Sudafed)

46
Q

prototype for intranasal decongestant (sympathomimetic)

A

oxymetazoline (Afrin)

47
Q

re: allergic rhinitis, how are decongestants (sympathomimetics) working?

A

alpha 1 agonist –> acting on vessels –> constricting –> decrease secretions –> decrease congestion

48
Q

SE of pseudoephedrine

A

HTN, insomnia

49
Q

which patients should we NOT use pseudoephedrine with?

A

cardiac patients - stimulating the SNS system so this drug impacts the heart!

50

with oxymetazoline (Afrin), what is that patient at risk for? how can we combat this?

A

rebound congestion w/cessation

USE NO MORE THAN 3-5 DAYS
