Levalbuterol HCl(Levosalbutamol tartrate) is a relatively selective beta2-adrenergic receptor agonist used for the treatment of asthma.
Racemic albuterol (7.5 mg, bid) results in a greater improvement in their forced expiratory volume in 1 second (FEV1) as well as in their asthma scores after 1 hour of continuous treatment compared to the Levalbuterol (3.75 mg, bid) administration in children with asthma. The greater improvement in asthma scores is maintained after the second hour of continuous therapy in the racemic albuterol group but not for forced expiratory volume in 1 second (FEV1) measurements. [1] Levalbuterol (1.25 mg) requires significantly fewer median total nebulizations and scheduled nebulizations compared with those in the racemic albuterol (2.5 mg) group in patients with asthma or chronic obstructive pulmonary disease (COPD). Disease symptom assessment and subject general well-being score scores improves significantly from baseline in both levalbuterol (1.25 mg) and racemic albuterol (2.5 mg) treatment groups, and beta-mediated adverse effects mean scores are significantly greater with levalbuterol versus racemic albuterol.

Trends in Medicaid spending on inhalers in the United States, 2012-2018
J Manag Care Spec Pharm 2021 Dec;27(12):1744-1749.PMID:34818085DOI:10.18553/jmcp.2021.27.12.1744.
BACKGROUND: Chronic obstructive pulmonary disease (COPD) and asthma are common respiratory diseases that impose a significant economic burden on Medicaid. Inhalers are the mainstay treatment for relieving symptoms and improving outcomes for COPD and asthma patients. OBJECTIVE: To describe the total spending and trends of Medicaid expenditures on inhalers between 2012 and 2018 in the United States. METHODS: We analyzed the deidentified data from the Medicaid Drug Spending Dashboard and utilization datasets from 2012 to 2018. We identified 9 classes of inhalers and described the Medicaid total spending on and relative annual changes for those inhalers. We also described the spending on available generic inhalers and compared the Medicaid spending by manufacturers during this time frame. RESULTS: Medicaid spent $26.2 billion on inhalers from 2012 to 2018. This spending increased by $2.5 billion (120%) over this time frame. During this specified period, the highest Medicaid spending was on the group of inhaled corticosteroid (ICS)-containing inhalers ($14.9 billion). Within this group, the inhaler class of ICS/long-acting beta-2 adrenoceptor agonists contributed to the highest Medicaid spending (53%), with a growth of 607% between 2012 and 2018. Of the $26.2 billion that Medicaid spent on inhalers, $35.5 million (less than 0.01%) was spent on 2 generic inhalers: fluticasone propionate with salmeterol and Levalbuterol tartrate hydrofluoroalkane. CONCLUSIONS: Between 2012 and 2018, on average, $3.5 billion per year was spent by Medicaid on inhalers. Decreasing the price of inhalers by introducing more generic inhalers in the market can potentially reduce the cost burden on Medicaid.

Practical methods for improving flow properties of active pharmaceutical ingredients
Drug Dev Ind Pharm 2009 Dec;35(12):1460-9.PMID:19929205DOI:10.3109/03639040903025830.
Objective: The essential aim of this article is to develop effective methods for improving the flow properties of active pharmaceutical ingredients (APIs) without requiring particle size or shape modification. Methods: The 'formulation' approach used here focuses on enhancing flow properties of three chemically different drug powders (micronized acetaminophen, Levalbuterol tartrate, and didesmethylsibutramine tartrate) by using small amounts of lubricants, glidants, and other additives, both individually and in combination. Additives are intimately mixed using a laboratory-scale V-blender with an intensifier bar. Flow index, dilation, and electrical impedance were measured for a total of 24 blends. Results: The flow behavior of all three APIs improved with the addition of these additives. Relative effectiveness of different additive combinations displayed remarkable consistency for all three APIs. Simultaneous presence of SiO2, MgSt, and talc led to substantial decreases in cohesiveness, causing major improvements in flowability of powder. All three properties showed a very tight correlation. Conclusions: Drug powders with improved flow were found to exhibit low dilation and low impedance values. A common linear correlation between flow index and impedance and also between dilation and impedance was observed for all three APIs, indicating that electric properties play a substantial role in the cohesivity of all three APIs, and suggesting the presence of a common mechanism for the emergence (and mitigation) of cohesive phenomena.
