Q

Omalizumab

A

A anti-IgE antibody. used to prevent the sensitization of mast cells and basophils.

ONLY used when environmental or occupational allergens provoke asthma.

Block Box warning -> can produce anaphylaxis as easy as after first dose or up to a year later. (have EPI on hand)

Q

Theophylline

A

this drug has both characteristics of a asthma reliever as well as a controller.

Given Orally

Has a very narrow therapeutic window. (10-20mg/L)

Inhibits PDE4 to increase cAMP as well as blocks adenosine receptors

Side effects can be like caffeine stimulated the CNS making nervousness and restlessness.

Q

SABA’s

A

should be used as soon as onset of symptoms or 10 min before exposure.

Albuterol -> inhaled
Levalbuterol -> inhaled
Metaproterenol -> oral
terbutaline -> oral

Q

LABA’s

A

used in long term therapy when you are using a SABA to much

Salmeterol
formoterol

Never given as mono therapy because a increased risk of death.

16
Q

contraindicated drugs

A

Any Beta antagonist

Suffix -lol

17
Q

Contraindications in Corticosteroid therapy

A

Children -> inhibit grown

Adults -> can cause thrush because of immunosuppression (wash mouth out with water)

Post menopausal women systemic dosing -> can aggravate osteoporosis

18
Q

Prednisolone

A

Systemic Corticosteroid

Used for severe asthma attacks and should be tapered off once control is established

Slow onset because they effect gene transcription

has a high first pass metabolism

suppress inflammatory genes and express anti-inflammatory genes

19
Q

Dexamethasone

A

Systemic Corticosteroid

Used for severe asthma attacks and should be tapered off once control is established

Slow onset because they effect gene transcription

has a high first pass metabolism

suppress inflammatory genes and express anti-inflammatory genes

20
Q

Moderate persistent asthma

A

a patient that has a daily attack

FEV1 -> 60-80%

give medium dose ICS plus LABA

use SABA for attacks

21
Q

Mild persistent asthma

A

A patient that has a attack more than 2 times per week.

FEV1 is near normal

Give ICS as well as still using the SABA

22
Q

Combination products

A

Budesonide/ formoterol
Fluticasone/ salmeterol

Used in moderate persistent asthma or sever persistent asthma.

Important to use combination drugs because monotherapy with a LABA has a increased risk of death.

23
Q

Salmeterol

A

A LABA that you never want to use as montotherapy because it has a increased risk for death. give with another controller medication

24
Q

formoterol

A

A LABA that you never want to use as montotherapy because it has a increased risk for death. give with another controller medication

25
peptide leukotrienes
LTC4, LTD4, LTE4
26
Aspirin-sensitive asthma
Associated with excessive leukotriene production. Give Zileuton, Montelukast, Zafirlukast.
27
Excercise induced asthma
leukotriene modifiers Zileuton, Montelukast, Zafirlukast all work to the same degree to prevent exercise induced bronchospasm.
28
Aminophylline
Inhibits PDE4 to increase cAMP as well as blocks adenosine receptors Given IV Side effects can be like caffeine stimulated the CNS making nervousness and restlessness.
29
COPD Patient characteristics
SMOKER Older than 35 Chronic Productive cough (caused by excessive vagal stimulation -> caused bronchioconstriction and mucus secretion) Breathlessness symptoms are often constant and don't vary.
30
Asthma patient characteristics
Some are smokers Often will be below 35 Y.O. Rarely have a cough Commonly have nocturnal breathlessness Commonly have a day to day variation in symptoms.
31
Ipratroprium
A Muscarinic receptor antagonist that is charged. this prevents it from entering the CNS. Short Acting with a quick onset (15 min) Inhaled Less selective and will bind to M1,2 and 3 Used in COPD to receive bronco constriction and mucus production Can be used in asthma in patients that don't tolerate or respond to beta-2 stimulation (SABA/LABA)
32
Tiotropium
A Muscarinic receptor antagonist that is charged. this prevents it from entering the CNS. Long lasting drug (24 hrs) that has a onset of 30 min Used in COPD to receive bronco constriction and mucus production Can be used in asthma in patients that don't tolerate or respond to beta-2 stimulation (SABA/LABA)
33
Muscarinic stimulation of the airway
Controlled via the Vagus nerve.
34
Methacholine
used in the methacoline challenge that stimulated the muscarinic receptors not the bronchiole smooth muscle and if constriction is more than normal at a lower dose they have asthma or hyper-reactive airway
35
Roflumilast
Oral PDE-4 inhibitor that is used in COPD patients.
36
Drugs contraindicated in COPD
Leukotriene modifiers -> no pathogenic role in COPD Systemic glucocorticosteroids because of a increased risk for infection.
