Diagnosing Bronchial Asthma

Asthma tests may include:

• Spirometry: A lung function test to measure breathing capacity and how well you breathe. You will breath into a device called a spirometer.
• Peak Expiratory Flow (PEF): Using a device called a peak flow meter, you forcefully exhale into the tube to measure the force of air you can expend out of your lungs. Peak flow monitoring can allow you to monitor how well your asthma is doing at home.
• Chest X-ray: Your doctor may do a chest X-ray to rule out any other diseases that may be causing similar symptoms as pneumonia.

*Relievers (Quick)

*Controllers (long term)

*Patient education

 Relievers

-Short-acting inhaled β2-agonists

–Salbutamol,   Terbutaline

-Long-acting oral β2-agonists

–Salmetrol,  Formroterol

-Anti-cholinergics

–Ipatropium, Tiotropium give synergestic bronchodilatation BUT of more benefit in COPD

Preventers  

Inhaled corticosteroids

=Budesonide/ beclomethasone/ fluticasone – use any

=Start (400-1000 mcg/day approx. in 2 divided doses)

=Maintain for 3 months

=Taper slowly and keep at 200 mcg

=Safe for long-term use (years)

Famous available drugs :

lClenil modulite = Beclomethasone

Symbicort = Budesonide  + Formoterol

Pulmicort = budesonide

Seretide  = Fluticasone + Salmeterol

Flixotide = fluticasone

Foradil = formoterol

Atrovent = ipratropium bromide

Spiriva = tiotropium

Leukotrine receptor antagonist 

Benefit in exercise induced asthma – ch  rhinitis

2- Add inhaled steroid at 200-800 mcg/d (400 appropriate)

3- Add LABA : A- Good Control àcontinue    

                          B- Inadequate àincrease C/S 

                          C- No response à stop LABA increase C/S  & if still less controlled à+ trial leuktrienes or SR theophylline

4- Trial :  - C/S 2000 mcg/d   - Leuk     - SR theoph.  . Oral SABA 

5- Daily Steroid tab at lowest dose OR anti IgE . Continue maximum dose inhaled steroids .
