How do generic levalbuterol tartrate inhalers work?
Generic levalbuterol tartrate inhalers work by delivering the active ingredient directly to the lungs. Levalbuterol is a bronchodilator, a type of medication that relaxes the muscles lining the airways in the lungs. This widening of the airways helps to relieve symptoms of breathing problems, such as wheezing and shortness of breath [4]. It is the (S)-enantiomer of albuterol [5].
What conditions are treated with levalbuterol tartrate?
Levalbuterol tartrate is used to treat bronchospasm in patients with asthma. It is available as a metered-dose inhaler (MDI) and a nebulizer solution [4].
How does generic levalbuterol tartrate compare to branded Xopenex?
Generic levalbuterol tartrate is bioequivalent to the branded Xopenex. This means that the generic version delivers the same amount of active ingredient into the bloodstream over the same period as the branded drug. Regulatory agencies like the U.S. Food and Drug Administration (FDA) require generics to meet strict standards for safety, quality, and effectiveness before they can be approved [1][4].

What is the difference between levalbuterol and albuterol?
Levalbuterol is the (S)-enantiomer of albuterol, meaning it is a specific mirror-image form of the albuterol molecule. Albuterol is a racemic mixture, containing both the (S)-enantiomer (levalbuterol) and the (R)-enantiomer. Levalbuterol is believed to be the active bronchodilating component of albuterol, and some studies suggest it may have a more favorable side effect profile compared to racemic albuterol, although this is a subject of ongoing discussion and clinical evaluation [5].
How is levalbuterol tartrate administered?
Levalbuterol tartrate is administered through inhalation. It is available as a metered-dose inhaler (MDI) for use with or without a spacer, and as a solution for nebulization [4].

The cost of generic medications is typically lower than their branded counterparts. The price of generic levalbuterol tartrate can vary depending on the manufacturer, pharmacy, and insurance coverage [1].
