Key takeaways
Atrovent HFA (ipratropium) and Duoneb (ipratropium/albuterol) are both used to treat chronic obstructive pulmonary disease (COPD), but they have some key differences. Atrovent HFA is a short-acting muscarinic antagonist (SAMA) that comes in an inhaler form and is used regularly throughout the day to help keep your airways open. It is not a rescue inhaler and takes about 15 minutes to start working. On the other hand, Duoneb is a combination of ipratropium (SAMA) and albuterol, a short-acting beta-agonist (SABA), and is inhaled through a nebulizer. Duoneb starts working within minutes and combines two bronchodilators to improve breathing more effectively than using albuterol alone. However, it requires a nebulizer machine, making it less convenient. Both medications have similar side effects, such as lung problems and sore throat, but Duoneb also carries a risk of heart-related side effects due to the albuterol component.
