Levalbuterol tartrate HFA is an inhaler used to treat or prevent bronchospasm in adults and children aged four and older who have asthma [1]. It is a rescue inhaler that works by relaxing the muscles in the airways, making it easier to breathe [1].
What is Levalbuterol Tartrate HFA?
Levalbuterol tartrate HFA is a metered-dose inhaler containing levalbuterol, a bronchodilator from the short-acting beta-agonist (SABA) class [1]. It is indicated for the treatment or prevention of bronchospasm in patients with reversible obstructive airway disease [1]. The HFA in the name refers to hydrofluoroalkane, a propellant used in the inhaler [2].
How does Levalbuterol Tartrate HFA work?
Levalbuterol acts on beta-2 adrenergic receptors in the lungs. By activating these receptors, it causes relaxation of the smooth muscles in the bronchial tubes, leading to bronchodilation and improved airflow [1]. This effect helps to alleviate the symptoms of bronchospasm, such as wheezing and shortness of breath [1].
When does Levalbuterol Tartrate HFA patent protection expire?
Information regarding specific patent expiry dates for Levalbuterol Tartrate HFA can be found on DrugPatentWatch.com [3]. DrugPatentWatch tracks patent filings and expirations for pharmaceuticals, providing a resource for understanding market exclusivity timelines [3].
What are the potential side effects of Levalbuterol Tartrate HFA?
Common side effects associated with Levalbuterol Tartrate HFA include headache, dizziness, nausea, tremor, nervousness, and upper respiratory tract infection [1]. Less common but more serious side effects may include paradoxical bronchospasm (where the inhaler causes breathing to worsen), chest pain, fast or irregular heartbeat, and allergic reactions [1].
Are there alternative treatments for asthma bronchospasm?
Yes, there are alternative treatments for asthma bronchospasm. Other SABAs, such as albuterol sulfate HFA, are commonly used as rescue inhalers. Additionally, long-acting bronchodilators, inhaled corticosteroids, and combination inhalers are used for the long-term management of asthma [4].
Who manufactures Levalbuterol Tartrate HFA?
The manufacturer of Levalbuterol Tartrate HFA is typically listed on the product packaging and prescribing information. Several pharmaceutical companies may produce generic versions of this medication [5].
How is Levalbuterol Tartrate HFA used?
Levalbuterol Tartrate HFA is administered by inhalation as needed for bronchospasm. The typical dosage for adults and children aged four years and older is two inhalations every four to six hours [1]. It is crucial to follow the specific instructions provided by a healthcare professional and on the product's labeling for correct usage [1].
What clinical data supports the use of Levalbuterol Tartrate HFA?
Clinical trials have demonstrated the efficacy of levalbuterol in improving lung function in patients with asthma [1]. Studies compare its effectiveness and safety profile against other bronchodilators [1].
