Introduction to Levalbuterol Hydrochloride
Levalbuterol hydrochloride, formerly known under the brand name Xopenex, is a beta-2 agonist and bronchodilator used primarily for the treatment of reversible obstructive airway disease, such as asthma. Here, we will delve into the clinical trials, market analysis, and future projections for this drug.
Clinical Trials Overview
Adults and Adolescents ≥12 Years Old
Clinical trials involving adults and adolescents aged 12 years and older have demonstrated the efficacy and safety of levalbuterol hydrochloride. A 4-week, randomized, double-blind, placebo-controlled study involved 362 patients with mild to moderate asthma. Patients were randomly assigned to receive levalbuterol 0.63mg, levalbuterol 1.25mg, racemic albuterol sulfate 1.25mg, racemic albuterol sulfate 2.5mg, or placebo, administered three times a day via a nebulizer. The results showed that all active treatment regimens demonstrated significant improvements in FEV1 (forced expiratory volume in one second) compared to the placebo group on both day 1 and day 29. Levalbuterol 1.25mg showed the largest mean percent change from baseline FEV1[1].
Children 6 to 11 Years Old
In children aged 6 to 11 years, a randomized, double-blind, placebo- and active-controlled study was conducted. This study involved 316 patients with mild to moderate asthma, who were randomly assigned to receive levalbuterol (0.31mg or 0.63mg), racemic albuterol (1.25mg or 2.5mg), or placebo, delivered three times a day for three weeks. The results indicated that all active treatment regimens showed significant improvements in FEV1 compared to the placebo group on day 1 and day 21. The onset and duration of effect for levalbuterol were clinically comparable to those of racemic albuterol[1].
Pediatric Patients Under 4 Years Old
Clinical trials in pediatric patients under 4 years of age were conducted to meet the requirements of the Pediatric Research Equity Act (PREA). One of the trials, Study 051-359, was a modified-blind, placebo-controlled trial that evaluated the effectiveness of Xopenex HFA (levalbuterol tartrate) in reducing asthma symptoms. However, the data did not support the extension of the Xopenex HFA indication to pediatric patients under 4 years of age[3].
Market Analysis

Regulatory Landscape
FDA Guidelines and Approvals
The FDA has played a crucial role in the approval and regulation of levalbuterol hydrochloride. For instance, the supplemental NDA for Xopenex HFA (levalbuterol tartrate) was approved, but it did not extend the indication to pediatric patients under 4 years of age due to insufficient data[3].
Upcoming Product-Specific Guidances
The FDA is continually updating product-specific guidances to support the development of generic drug products. While levalbuterol hydrochloride is not specifically mentioned in the upcoming guidances, the updates on related inhalation products (e.g., albuterol sulfate) can influence the broader respiratory drug market[4].
Conclusion
Levalbuterol hydrochloride has established itself as an effective bronchodilator for the treatment of asthma and other reversible obstructive airway diseases. The clinical trials have demonstrated its efficacy and safety in various patient populations, although more research is needed for pediatric patients under 4 years old. The market analysis indicates strong growth potential driven by increasing demand, technological advancements, and expanding geographical reach.
