Results [median (range)] of allergen bronchial challenge
performed immediately after exposure to formaldehyde or air-only and methacholine bronchial challenge
performed 8 hr after exposure.
Bronchial challenge testing with ARIDOL should be used only as part of a physician's overall assessment of asthma.
Bronchial challenge testing with ARIDOL is for diagnostic purposes only.
Unlike other bronchial challenge
tests, ARIDOL is a single-use test that requires less preparation time and eliminates reconstitution, use of a nebulizer to administer, clean-up and sterilization.
It is the first and only bronchial challenge
test approved Europe-wide.
With seven to 15 per cent of asthma patients currently referred for a bronchial challenge
test and up to 160,000 tests undertaken annually, Korea represents an important base from which to launch Aridol into the Asian market.
The bronchial challenge
testing market is dominated by methacholine and is one of few European markets where testing to assess effectiveness of treatment is performed.
This is important since Aridol has recently become the first bronchial challenge
test to be approved in a European country as an aid to asthma control.
and Europe includes the existing 400,000 bronchial challenge
tests performed yearly, 2 million new tests for assisting the diagnosis of asthma and 16 million new tests performed by pulmonary specialists and primary care physicians for assisting the management of asthma.
A variety of other tests are often helpful in narrowing the differential diagnosis--for example, chest imaging, blood eosinophil measurement, allergy testing, bronchial challenges
, diffusing capacity of the lung for carbon monoxide, lung volumes, and elasticity.
Spirometric tests and bronchial challenges
were performed in the Respiratory Laboratory.
