Q

in persistent asthma we start treating by ____ for adults & ______ for childrens

A

low dose inhaled corticosteroids

montelukast (leukotriene antagonist)

18
Q

montelukast is used for ____ instead of

A

persistent asthma in children

inhaler corticosteroids

19
Q

if low dose of inhaled corticosteroids in persistent asthma not enough/not controlled we ?+ if that didnt work ?+didnt work ?

A

increase the inhaled corticosteroids to medium dose + LABA or montelukast.

high dose of corticosteroids + LABA or montelukast.

oral systemic corticosteroids (high systemic adverse effect).

20
Q

step up bronchial asthma treatments

A

1-SABA

2-low dose inhaled corticosteroids {adult}
montelukast (leukotriene antagonist){child}

3-corticosteroids medium dose + LABA or montelukast

4-high dose of corticosteroids + LABA or montelukast.

5-oral systemic corticosteroids (high systemic adverse effect).

21
Q

inhaled albuterol is an broncho___ + adv to asthmatic patient

A

bronchodilator

rapidly effective, safe, and inexpensive.

22
Q

Patients with only occasional symptoms of asthma require only _?as___

A

bronchodilator as albuterol

23
Q

additional treatment is needed in which cases ?

A

 If symptoms require this “rescue” therapy more than twice a week.
 If nocturnal symptoms occur more than twice a month.
 Or if the FEV1 is less than 80% of predicted.

24
Q

The treatment first recommended in PERSISTENT asthma patient is a low dose of

25
for patients who are unable to coordinate inhalation from a metered-dose inhaler ___ therapy is used
Nebulized therapy
26
what type of Adrenergic agonistis used for asthmatic patient and what not ?
beta 2 agonist causes bronchodilator | not epinephrine because of beta 1
27
how beta2 agonist help in bronchodilating ?
β2-agonist stimulate adenylyl cyclase thus increase cAMP smooth muscle relaxation and bronchodilation.
28
Side effects of B agonists:
tremor, tachycardia . Decreases in serum | potassium levels. (Dose-dependent)
29
salbutamol (Albuterol) is +for + onset +duration of action
SABA acute attacks of bronchial asthma Rapid onset 5-10min short acting 4h
30
examples of LABA &SABA
Salmeterol ,Formeterol | salbutamol
31
Salmeterol ,Formeterol/LABA duration of acting onset taken with ? can be taken alone ?
``` 12-24h long acting Slow onset (15-30min) corticosteriod / no mamno3 ```
32
Ipratropium bromide is
Muscarinic antagonists
33
Muscarinic antagonists as Ipratropium bromide onset acting duration first line for
10-15min slower thanSABA slow 3-5h COPD
34
first line for COPD
Muscarinic antagonists as Ipratropium bromide
35
``` Theophylline : methylxanthine.  It is ___absorbed cheap/expensive oral broncho___.  Improves the strength of ____ of diaphragm.  Inhibit ___thus increase ___ (cAMP/PDE4). smooth muscle ____ ____the heartrate ```
``` Well - cheap -dilator contraction PDE4 - cAMP RELAXANT increase ```
36
Cromolyn which is ____ stabilizer, increase/decrease the degranulation of mast cells increase/decrease the release of the mediator from the mast cells
mast cell decrease decrease
37
the most important route for chronic use
Inhalation: Beclomethason
38
Beclomethason route
inhalation
39
prednislon is used when ?taken (route)?
severe uncontrolled cases, when the patient is not responding to inhaled corticosteroid & LABA . orally
40
Injection: methylprednisolone, hydrcortison | is used in ?
severe uncontrolled cases in the ER.
41
methylprednisolone, hydrcortison route ?
Injection
