Case report: Paradoxical responses to short acting beta-agonists in a pediatric patient.
Conclusion: This case highlights the need to include paradoxical response to SABAs in the differential of a patient with poorly controlled asthma. It also provides an example of successful treatment of a pediatric patient with a class of medications previously reserved for adults with chronic obstructive pulmonary disease.

Short-acting bronchodilators for in-hospital management of acute exacerbation of COPD: Systematic Review
Introduction: No specific guidelines exist for administration of short-acting bronchodilator (SABD) for people hospitalised with acute exacerbation of chronic obstructive pulmonary disease (AECOPD); despite routine use in practice and risk of cardiac adverse events.Aim: To review evidence underpinning use and optimal dose, in terms of risk versus benefit, of SABD for inpatient management of AECOPD.Methods: A systematic search of Medline, Embase, CENTRAL and grey literature was conducted (up to December 2017) to identify relevant randomised controlled trials (RCT) or controlled clinical trials (CCT). Review methods were in ...

Enantiomeric impurity analysis using circular dichroism spectroscopy with United States Pharmacopeia liquid chromatographic methods
In this study, HPLC-CD was evaluated for enantiomeric purity determinations of 13 drug substances using HPLC methods consistent with assay protocols described in United States Pharmacopeia (USP) monographs. Of these selected substances, three (sitagliptin, timolol, and levalbuterol) showed no CD activity and one other (levofloxacin) could not be analyzed due to incompatibility of the mobile phase with the CD detector. For the remaining 9 substances, method validation was performed to determine the linearity, accuracy, precision and limits of quantitation of enantiomer impurities, which was compared to limits established by...

Change in Oxygen Consumption Following Inhalation of Albuterol in Comparison with Levalbuterol in Healthy Adult Volunteers
We examined changes in oxygen consumption (V ’O2) and heart rate (HR) following administration of albuterol and levalbuterol.MethodsThis is a prospective, randomized, single-blinded, controlled study of healthy adult volunteers. Subjects separately received albuterol (5  mg) and levalbuterol (2.5 mg) aerosolized over 15 min. V’O2 and vital signs were measured before the medications and 5, 10, 20, 40, and 60  min after.ResultsWe enrolled 24 volunteers with a median age of 32 years. Compared to baseline, there was a significant maximum increase in V ’O2 following administration of both a...

Clinical outcomes of levalbuterol versus racemic albuterol in pediatric patients with asthma: Propensity score matching approach in a medicaid population
ConclusionThis observational study of children aged 2–18 demonstrated levalbuterol prescription fills were associated with reduced ED visits, but not hospitalizations. Additional research may be necessary to assess this association. Pediatr Pulmonol. © 2016 Wiley Periodicals, Inc. (Source: Pediatric Pulmonology)

Efficacy of Inhaled Levalbuterol Compared to Albuterol in Horses with Recurrent Airway Obstruction
Conclusions and clinical importanceLevalbuterol is as effective a bronchodilator as albuterol; although levalbuterol lasts twice as long as albuterol, its duration of action is still too short to make it practical for RAO treatment. (Source: Journal of Veterinary Internal Medicine)

Clinical outcomes and treatment cost comparison of levalbuterol versus albuterol in hospitalized adults with chronic obstructive pulmonary disease or asthma.
CONCLUSION: Clinical outcomes were similar with the use of levalbuterol versus albuterol for exacerbations of COPD or asthma. On average, patients receiving levalbuterol had longer and more costly hospital stays. PMID: 26025994 [PubMed - in process] (Source: American Journal of Health-System Pharmacy : AJHP)

Advances in acute asthma
Purpose of reviewThe purpose of this study is to highlight some of the recent findings related with the management of acute exacerbations in the context of the emergency department setting. Recent findingsβ2-agonist heliox-driven nebulization significantly increased by 17% [95% confidence interval (CI) 5.2–29.4] peak expiratory flow, and decreased the rate of hospital admissions (risk ratio 0.77, 95% CI 0.62–0.98), compared with oxygen-driven nebulization. Other findings indicate that there is no robust evidence to support the use of intravenous or nebulized magnesium sulphate in adults with severe acute a...

Validation of a population‐based method to assess drug‐induced alterations in the QT interval: a self‐controlled crossover study
ConclusionsQT prolonging effects were common and varied in strength. Our results lend support to past Food and Drug Administration regulatory actions and support the role for ongoing surveillance of drug‐induced QT prolongation.
