Mannitol challenge test (Aridol™) + short-acting β2-agonist - positive response. [ Time Frame: One day only (Day 1). Subjects complete an ACT, the mannitol challenge test and the reversibility test. This is the end of the study, there is no follow up. ]
For the Primary efficacy variable, positive response Mannitol challenge test (Aridol™) followed by short-acting β2-agonist will be given as number and percentage for the ITT-population, as defined by the following: ≥15% fall in FEV1 from baseline; 10% incremental fall in FEV1 between two consecutive doses in the test; Reversibility test with a short-acting β2-agonist - increase in FEV1 of ≥15% from the last dose of mannitol in the challenge test.

Mannitol Challenge Test in Adult Asthma Patients With Fixed Dose Combinations
An Open-label Single Site Single Dose Pilot Study Using Mannitol Challenge Test With the Purpose to Explore Treatment With Fixed Dose Combinations in Adult Subjects With Asthma in Primary Care in Sweden

The primary objective in this pilot study is to explore if asthma patients prescribed fixed dose combinations (budenosid/formoterol (Symbicort®), salmeterol/fluticasone (Seretide®), beclometasone/formoterol (Innovair®) are optimal treated regarding the mannitol challenge test and the following reversibility test.

The primary endpoint is to identify asthma patients responding positive or negative to the mannitol challenge test and/or the reversibility test.

The hypothesis is that not all patients are well treated.

Phase 4
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Drug: Mannitol challenge test & reversibility test
Patients perform an asthma control test (ACT) to establish if they are "well controlled" or "symptomatic". All patients will perform then perform the mannitol challenge test. Aridol™ is an indirect osmotic bronchial challenge test which can be used to identify bronchial hyperresponsiveness
Experimental: Inhaler
Subjects prescribed fixed dose combinations perform Mannitol Challenge Test and Reversibility Test once
Intervention: Drug: Mannitol challenge test & reversibility test
