Bronchial Provocation Study

Purpose

The purpose of the inhaled bronchial provocation study using PROVOCHOLINE® is to determine how responsive (or irritable) your airways are and to determine the severity of asthma, if present.

Test

You will be asked to inhale a mist that contains different concentrations of PROVOCHOLINE® . The mist is produced by a device called a nebulizer and you will inhale the mist through a mouthpiece. Before and after testing begins, you will be asked to blow forcefully into pulmonary function testing equipment. The test may take up to 3 hours to complete.
