Summary
Exercise Induced Laryngeal Obstruction (EILO) is a condition not uncommon in otherwise
healthy young people. EILO is caused by posteromedial collapse of supraglottic structures or
medialization of the vocal folds, or both, during high intensity exercise. There are
currently no treatments available that is properly evidence based. However, case reports
suggest a possible effect from the "asthma drug" Ipratropium Bromide (Atrovent®). The current
project is an open label pilot study, aiming to test if Atrovent can influence the occurence
of EILO, either postponing the onset during exercise or fully prevent the condition to occur.
