Q

Glucocorticoids - MOA

A

– Suppress inflammation
– Most effective anti-asthma drug
– Decrease synthesis and release of inflammatory mediators
– Reduce infiltration and activity of inflammatory cells
– Decrease edema of the airway mucosa caused by beta2
agonists
– Reduce bronchial hyperactivity and decrease airway
mucus production
– May increase the # of bronchial beta2 receptors and their
responsiveness to beta2 agonists

Q

Oral glucocorticoid use

A

– Management of acute exacerbations
– Short burst, use shortest duration possible
– Use when symptoms cannot be controlled with safer
medications.

20
Q

Oral glucocorticoid ADR

A

Adverse effects: adrenal suppression, osteoporosis,
hyperglycemia, peptic ulcer disease.
• Growth suppression in the young patient.

21
Q

Oral glucocortoid recomendatiosn to avoid Adverse effects

A

eat calcium. Weight bearing exercise. Vit d

22
Q

High dose inhalled glucocortoid ADR

A

catarax and glacoma

23
Q

should use oral glucocortoic less than

A

10 days. Really the shortest duration possible

24
Q

• Prolonged glucocorticoid use can decrease

A

the ability
of the adrenal cortex to produce glucocorticoids of its
own

25
High levels of glucocorticoids are required to s
o survive | severe stress
26
Adrenal suppression prevents p
production of | endogenous glucocorticoids
27
Patients must be given increased doses of
oral or IV | glucocorticoids at times of stress
28
failure to increase dose of glucocorticoids during times of stress
can prove fatal
29
addrenal supression is life threatnein gat times of
s of severe physiologic stress | e.g., surgery, trauma, or systemic infection
30
Discontinuation of systemic glucocorticoid
– Most be done slowly – Recovery of adrenocortical function takes several months – Dosages of exogenous sources must be gradually reduced – During this patient must be given oral or IV glucocorticoids at times of severe stress
31
In children there is A dose-dependent reduction in bone | formation with use of
inhaled corticosteroids
32
• Vitamin D and calcium sufficiency should | be ensured with
adequate dietary intake of | vitamin D and calcium
33
Oral Glucocorticoids examples
Prednisone, methylprednisolone, | prednisolone
34
Oral Glucocorticoids adult dose
40 to 60mg/day for 3 to 10 days
35
Oral Glucocorticoids pediatric dose
1 to 2 mg/kg/day for 3 to 10 | days
36
Oral Glucocorticoids SE
increased appetite. Increased energy.
37
Oral Glucocorticoids recomendations
take with food. taper dose 60, 40, 20 ect.
38
Leukotriene Modifiers action
suppress effects of leukotrienes
39
leukotriens
Promote smooth muscle constriction, blood vessel permeability, and inflammatory responses through direct action and recruitment of eosinophils and other inflammatory cells
40
In patients with asthma, leukotriene | modifiers can reduce
bronchoconstriction and inflammatory responses such as edema and mucus secretion
41
Leukotriene modifieres are considered
second line agents.
42
Leukotriene modifiers Adverse Neuopsychiatric effects
including | depression, suicidal thinking, and suicidal behavior
43
• Zileuton [Zyflo] action and monitoring
– blocks leukotriene synthesis – Monitor ALT (one a month for 3 months, then every 2 to 3 months x 1 year, then periodically).
44
Montelukast [Singulair} MOA
Leukotriene Receptor Blocker
45
Montelukast three indications
– 1. Prophylaxis and maintenance therapy – 2. Prevention of EIB >15 y.o. – 3. Relief of allergic rhinitis
46
Montelukast Side Effects
Neuropsychiatric effects
47
No serious drug interactions with
Montelukast
