Q

Fexofenadine drug class

A

Antihistamine

Second generation H1 receptor antagonist

22
Q

What does Fexofenadine do

A

Competes with histamine to bind at histamine receptor sites

Prevents histamine activation

23
Q

How is Fexofenadine different from diphenhydramine

A

Doesn’t cross the blood brain barrier so less CNS depression

24
Q

A

Allergic rhinitis

Minor allergies

Relief of pruritis

25
Q

Adverse effects of Fexofenadine

A

N/v

Dysmenorrhea

Fatigue

Headache

26
Q

Fexofenadine assessment

A

Less allergic symptoms
Nasal congestion
Improved pruritis

27
Q

Fexofenadine teaching

A

Avoid alcohol- increases sedative effect

Caution with antifungals and some abx- increases serum concentration

Take with water only- juice decreases absorption

28
Q

Albuterol drug class

A

Adrenergic

29
Q

What does albuterol do

A

Acts on beta 2 adrenergic receptors to relax bronchial smooth muscles

30
Q

Albuterol uses

A

Asthma and COPD

Exercise induced asthma

31
Q

What is a severe condition related to asthma

A

Status asthmaticus- life threatening severe asthma- unresponsive to bronchodilators

32
Q

Critically ill and older adult albuterol considerations

A

Oa: excess cardiac/CNS stimulation- caution

Critically ill- high doses for severe bronchoconstriction or SA

33
Q

Albuterol adverse effects

A

Tachycardia
Agitation
Tremor

34
Q

Albuterol contraindications

A

VT/SVT hx
Severe CAD
Caution in hypertension, hyperthyroidism, diabetes, seizures

35
Q

Albuterol assessment

A

Improved respiratory symptoms
Tachycardia and arrhythmia
Palpitations, tremor, CNS agitation
Frequent lung sounds

36
Q

Albuterol teaching

A

Maintenance vs rescue drugs

Nebulizer vs MDI

avoid excess caffeine

37
Q

3-5 minutes between drugs
Rinse mouth with water after

38
Q

Ipratropium bromide drug class

A

Anticholinergic

39
Q

What does ipratropium bromide do

A

Inhibits bronchconstriction and mucus secretion

40
Q

ipratropium bromide use

A

Ineffective alone for bronchospasm

Relieves bronchospasm with Albuterol in asthma, chronic bronchitis, and emphysema

41
Q

ipratropium bromide adverse effects

A

Cough
Nervousness
Nausea/GI upset
Headache
Dizziness

42
Q

ipratropium bromide contraindications

A

Hypersensitivity to atropine or ipratropium

Caution: glaucoma and prostate hypertrophy (anticholinergic)

43
Q

ipratropium bromide assessment

A

Better air entry

Improved RR

decreased wheezing

Anticholinergic effects

44
Q

Special ipratropium bromide consideration with nebulizer

A

Nebulizer in pts eyes lead to pupil dilation and blurry vision (anticholinergic)

45
Q

Beclomethasone drug class

A

Corticosteroid

46
Q

What does beclomethasone do

Decreases airway inflammation (inhaled)

47
Q

beclomethasone use

A

Asthma maintenance not rescue med

Late stage COPD

48
Q

Children and critically ill beclomethasone considerations
