Xopenex Nebulizer

Xopenex® (levalbuterol hydrochloride) is a medication used to treat or prevent airway spasms (bronchospasms), which can occur in people who have asthma or chronic obstructive pulmonary disease (COPD). This prescription medication is used as either an inhaler or in a nebulizer. When using a nebulizer, Xopenex is added to the device, which changes the liquid medication into fine droplets that are inhaled into the lungs.
Xopenex is part of a class of drugs called beta-adrenergic receptor agonists, or beta agonists for short. Beta agonists stimulate beta receptors in the body, including those on the muscles around the airways. This stimulation causes the muscles to relax, which opens up the airways and allows more air to get into and through the lungs. Xopenex also has some effects on decreasing the activity of mast cells in the lungs, which play an important role in inflammation and allergic reactions.
In clinical studies, Xopenex started working within 10 to 17 minutes, and the effects lasted for five to six hours on average. In some people, the effects lasted as long as eight hours.
