Q

Treatment for moderate/severe intermittent symptoms

A

Oral antihistamine or

IN antihistamine +/- decongestant, or

LTRA, or

Q

MoA of decongestants?

A

Direct and indirect a1 agonists that produce vasoconstriction of resp mucosa

22
Q

Need to be careful with these meds and people who already have arrhythmias, HTN, hyperthyroidism b/c they cause increased BP and HR and stroke risk

A

Decongestants

23
Q

Other SEs of decongestants besides the CV stuff…

A

CNS stimulation, urinary retention (careful in BPH), increased BG (careful in DM), rebound congestion, increased ICP, nasal irritation

24
Q

His favorite decongestant

A

Oxymetazoline IN

25
Synthetic a1-agonist used mainly for relief of eye redness, hemorrhoids, and nasal congestion
Phenylephrine | can cause extravasation/tissue necrosis when used IV
26
Direct-acting a1-a2 agonist used for ocular and nasal vasoconstriction
Oxymetazoline (Afrin; Visine LR)
27
Direct-acting a and B agonist (a>b) while also displacing NE from storage sites, used for nasal congestion
Pseudoephedrine
28
PSE is limited daily to 3.6g of PSE base and 30-day purchase limit to 9g PSE base, what’s PSE?
Pseudoephedrine
29
Decongestant DOC in pregnancy 2nd trimester or later (oral)
Pseudoephedrine (PSE)
30
Decongestant alternative marketed for people who are unable to take decongestants b/c HBP
Coricidin HBP | Dextromethorphan and Chlorpheniramine...aka AHs, but fail to target obstruction of nasal passages
31
Inhibits cysteinyl leukotriene, inflammatory mediator released by mast cells, on target cells...comparable efficacy to AHs, but less than IN steroids
Leukotriene Antagonist Montelukast (Singulair)
32
Care with this type of med in people with suicidal thoughts
Leukotriene antagonists like singulair
33
Anti-infl agents that inhibits the mediators of both the early and late phase reaction...MOST EFFECTIVE DRUGS FOR AR RELIEVING ALL FOUR SYMPTOMS
Intranasal Steroids
34
INSs are effective but how long do they tend to take to work?
Onset is just 1-2 days but max effects occur in 1-2 weeks
35
AEs of INSs are mild: drying, stinging, epistaxis, after taste, except one bigger concern in peds, which is? Also tell pts to spray away from nasal septum
Growth suppression
36
The three most important INSs to know are:
Fluticasone Propionate (Flonase) Fluticasone Furoate (Veramyst) Mometasone (Nasonex) B/c they are all the least lipophilic
37
Dymista
...
38
Muscarinic antagonist resulting in decreased nasal mucous secretion, and preg cat B...
Ipratropium nasal (Atrovent)
39
Initial DOC during pregnancy for rhinorrhea and sneezing are?
Mast cell stabilizers like Cromolyn Sodium (Nasalcrom)
40
Chart from slide 52
...
41
The most effective class of meds across the board for AR symptoms are?
INSs
42
Triad of symptoms in allergic conjunctivitis (pinkeye not from virus/bacteria)
Itching, conjunctival injection (redness), chemosis (conjunctiva swelling w/ or w/o watery discharge

...
46
Nonselective ocular AHs (H1 antagonists) that decrease itching and vasodilation
Azelastine (optivar) and Levocabastine (Livostin)
47
2nd gen ocular AHs
Ketotifen (Zaditor) and Olopatadine (Patanol)
48
Ocular decongestants include:
Naphazoline (Vasocon) is most potent Oxymetazoline (Visine LR) Tetrahydrozoline (Visine original)
49
Ocular mast cell stabilizers include
Cromolyn, lodoxamide, nedocromil (best b/c can do twice per day which is the least frequent dosing)
50
Ocular NSAID
Ketoralac (ASA so not for kids)
51
Ocular steroids, for more severe/chronic allergic conjunctivitis (specialist), ONLY ONE APPROVED FOR USE IN SEASONAL ALLERGIC CONJUNCTIVITIS:
Loteprednol AEs include cataracts, increase IOP, increase risk for ocular infection
52
Eye drop administration steps:
Wash hands -> tilt head black and pull lower lid down -> hold dropper close to eye, brace with hand -> squeeze dropper so single drop falls into pocket made by lower eyelid -> close eye for 2-3 min, tip head down, don’t blink/squeeze eyelid, place finger on tear duct and apply pressure, wipe excess, wait 5 min
