16
Q

Intranasal Glucocorticoids prevent and treat

A

seasonal/perennial rhinitis;now part of 1st line therapy

17
Q

Intranasal Glucocorticoids are

A

Anti-inflammatory action blocking histamine, prostaglandin, leukotrienes

18
Q

Intranasal Glucocorticoids adverse effects

A

Usually mild; drying of nasal mucosa, burning, sore throat, epistaxis, headache

19
Q

systemic effects of Intranasal Glucocorticoids are

A

rare at recommended doses

20
Q

Nasalcrom

A

Less effective than intranasal glucocorticoids; Blocks histamine release from mast cells; Best suited for prophylaxis

21
Q

Intranasal Cromolyn Sodium:

A

Nasalcrom

22
Q

Sympathomimetics:

A

Decongestantsphenylephrine (Neo-synephrine), pseudoephedrine (Sudafed, Afrin), oxymetazoline (Afrin) [not zertex or allergra]

23
Q

Sympathomimetics reduce

A

nasal congestion by activating alpha 1 adrenergic receptors on nasal blood vessels

24
Q

Sympathomimetics major adverse effect

A

Rebound congestion

25
Q

limit Sympathomimetics

A

to 3-5 days use then off for a few days (3 days on 2-3 days off) [there could be scar tissue and long term problems if on med for too long]

26
Q

other side effects of Sympathomimetics

A

CNS stimulation; Cardiovascular; Hemorrhagic Stroke

27
Q

CNS stimulation with sympathomimetics

A

(more common with oral sympthomimetics) restlesness, insomia, irritability, anxiety; CNS effects may lead these drugs to be drugs of abuse

28
Q

Cardiovascular effects with sympathomimetics

A

HTN, tachycardia-use with caution in heart, hypertensive population;

29
Q

Hemorrhagic Stroke with sympathomimetics

A

phenylpropanolamine (an alpha adrenergic agent) shown to cause hemorrhagic stroke in women

30
Q

Anti-histamine/Sympathomimetic Combination Drugs

A

Loratadine/pseudoephedrine: Claritin D; Fexofenadine/pseudoephedrien: Allegra-D

31
Q

D in Claritin D and Allegra D

A

sudafedrin

32
Q

Antitussives:

A

opioids suppress cough reflex in brain- codeine, hyrodcodone

33
Q

Codeine-

A

most effective; watch for respiratory suppression

34
Q

For overdose of Codeine-

A

naloxone (Narcan)

35
Q

Non-opioid:

A

dextromethorphan-also acts on the CNS suppressing cough reflex

36
Q

Expectorants- guaifenesin (Mucinex)

A

Stimulates flow of secretions, rendering a more productive cough

37
Q

Mucolytics:

A

make secretions more watery; helps produce more productive cough- acetylcysteine (Mucomyst), administered by inhalation [makes secretions so then you can cough them out]
