Q

how can we asses asthma control ?

A

by symptoms in the last 4 weeks :

day time asthma more than twice a week

night wakening due to asthma

reliver needed more than twice a week

activity limitation due to asthma

none of this = well controlled
1-2 of each - partially
3-4 of this = uncontrolled

Q

what are the side effects of inhaled corticosteroids ?

Q

what are the long acting b2 agonists ?

and are they administeered as monotherapy ?

A

salmeterol and formeterol = LABA

nerver inhaled as a monotherapy because they have minimal effcet i the chronic inflammtion in asthma = effcetive when combines with ICS better than doubling the dose of ICS

Q

what are the leukotrine receptor anatgonists ? and how are they administered

and what is their effect ?

A

montelucast = administered orally

reduces airway inflammtion and exacerbations , BUT SMALL BRONCHODILATOR EFFECT

Q

montelucast is especially used in ?

A

esp in children
as an alternative to ICS with MILD ASTHMA
patients with aspirin sensitive asthma
add on therapy (but less effective than LABA)

Q

what is the administration of sustained reease theophyline ?

and what is its main phsyiological effect ?

A

given orally twice a day

bronchodilator - by blockng phosphodiesterase and anagonist of adenosine

low dose = modest anti inflammatory

Q

what are the side effects of theophyline ?

A

it has a SMALL THERAPUTIC INDEX and conc above 40mg/dl can lead to arrythmia and seizures

if 10mg/kg/ day or more
CNS - anxiety , insomnia
cardio - tachycardia , arrythmia
GI = vomitting , nausea

Q

what are the drug to drug interactions we need to be carefull of in theophyline ?

A

metabolsim of theophyline increased in smokinh , rifampicin , phenobarbitural ,, carbemezapine = lower effect

metabolsim inhibited and toxicity leading to side effects by = ciprofloxacin (other fluroquinilones!) fluvoxamine , verapamil , diltizem , macrolides such as clarithro or erythromyccin

17
Q

what are the inhaled SABA ?

and how is saba used ?

A

salbutamol

used only in need bases , and for pretreatmnet in excercise indused bronchoconstriction

18
Q

what are the side effects of SABA ?

A

developments of tolerance

in the beginning thats why we see tremor and tacycardia but goes away

19
Q

what are the oral SABA?

A

salbutamol , clenbuterol , hexoprenaline

20
Q

what are the inhaled anticholinergic agents ?

A

ipratropium and tiotropium

21
Q

what is the indication for inhaled anticholnergeric agents ?

A

used for patients who have strong adverse tacchycradia and tachyarrythmia to SABA= bronchodilators but not as good as SABA

22
Q

what are the side effects of inhaled anti cholinergic agents ?

A

dry mouth

and bitter taste

23
Q

what are the short acting theophyline called ?

A

aminophyline = theophyline and ethylenediamine

24
Q

whata re the disadvantges of short acting theophyline ?

A

does not give additional bronchidilator effects over adeqeate doses of SABA

25
Q

whata re the anti-IgE add on therapy ? and how is it adminitered ? and what are the indications?

A

omalizumab
subcutaneous injection
uncontrolled step 4

26
Q

what are the systemic corticosteroids ?

how long does the oral therapy last?

A

prednisolone , prednisone and methyprednisolone

oral therapy lasts 5-7 das and then replaced with inhaled corticosteroids

27
Q

what are the side effects of the systemic corticosteroids ?

A

short term = hyperglycemia
gastroinetsnal - vomitting and diarrhea
change in mood

long term therapy = osteoperosis hypertension , diabetes mellitus , adrenal suppression , cataracts
glaucoma
skin thinning cutaneous stria
muscle weakness

28
Q

patients who recieve long term treatmnet of corticosteroids systemic should be additionally prescribed what ?

A

bisphosphonates for the bone

29
Q

what ais the step wise approach to control asthma?

A
step 1 (mild asthma) 
reliever = as needed SABA
controller = low dose ICS
or 
muscarinic antagonist (anticholinergic) 
oral SABA
short acting theophyline 
step 2 (mild asthma)
reliever = as needed SABA 
controller = low dose ICS 
or
or LTRA / low dose theophyline 
step 3 (moderate asthma )
reliever =as needed SABA / low dose ICS / formterol
controller = low dose ICS and LABA 
or
medium to high dose ICS 
low dose ICS and LTRA 
low dose ICS and sustained release of theophyline 
step 4 (severe asthma ) 
reliever = SABA / low dose ics / formeterol
controller = medium/ high dose ICS and LABA
or 
high dose ICS and LTRA 
high dose ICS and sustained release of theophylline
step 5 (severe asthma) 
reliever = SABA /LOW DOSE ICS/FORMTEROL
controller = anti IgE + LABA + MEDIUM TO HIGH DOSE ICS 
or 
add low dose CS
30
Q

what ais reffered to as mild asthma by the symptoms ?

A

day time symptoms of less than twice a month and short duration of few hours
no night awakening
and normal lung function of FEV1
