The mannitol challenge test (Aridol®/Osmohale®) is an indirect osmotic bronchial challenge test that can be used to identify bronchial hyperresponsivesness, a key clinical feature of respiratory conditions such as asthma.

Aridol/Osmohale is manufactured by Pharmaxis Ltd (Frenchs Forest, Sydney Australia) and is available as a standardised test kit containing pre-filled mannitol capsules and a hand held dry powder inhaler.

During a mannitol challenge test, the subject inhales increasing doses of mannitol with their lung function (Forced Expiratory Volume in one second- FEV1) measured after each dose to determine the level of bronchial hyperresponsiveness.
