Xopenex

Xopenex is a brand name for the drug Levalbuterol, a short-acting Beta2-adrenergic agonist used in the treatment of asthma and chronic obstructive pulmonary disease (COPD). It is manufactured by Sunovion Pharmaceuticals.

Pharmacology

Levalbuterol, the active ingredient in Xopenex, is a selective beta2-adrenergic receptor agonist. It works by relaxing the smooth muscles in the airways, allowing them to open up and make it easier for the patient to breathe. This makes it an effective treatment for conditions that cause narrowing of the airways, such as asthma and COPD.

Uses

Xopenex is primarily used to treat or prevent bronchospasm in people with reversible obstructive airway disease. It is also used to prevent exercise-induced bronchospasm. It can be used by adults and children who are at least 6 years old.

Side Effects

Common side effects of Xopenex include palpitations, chest pain, rapid heart rate, tremor or nervousness. If these effects persist or worsen, the patient should notify their doctor or pharmacist promptly.

Precautions

Before using Xopenex, patients should inform their doctor or pharmacist if they are allergic to it; or to similar drugs (such as albuterol, metaproterenol); or if they have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems.

Interactions

Drug interactions may change how medications work or increase the risk for serious side effects. Some products that may interact with Xopenex include beta-blockers (such as propranolol), tricyclic antidepressants (such as amitriptyline), and MAO inhibitors (such as phenelzine).
