Methacholine is the most commonly used stimulus in bronchoprovocation testing for the diagnosis of asthma. Methacholine causes bronchoconstriction in individuals with hyperresponsive airways, which is a hallmark feature of asthma. Acetylcysteine is a medication used to treat respiratory conditions, but is not used as a stimulus in bronchoprovocation testing. Leukotriene inhibitors and methylprednisolone are medications used to treat asthma, but are not used as stimuli in bronchoprovocation testing.
