Follow on Google News | Landmark Asthma Study Demonstrates Device Choice Determines Asthma ControlMonaghan Medical Corporation understands that for those with asthma, particularly children, choosing the device that best delivers their medication is an important consideration.
By: Monaghan Medical Corporation A landmark real-world study involving more than 18,000 asthma patients has demonstrated superior asthma control with the AEROCHAMBER PLUS® FLOW-VU® antistatic Valved Holding Chamber (VHC) compared with other chamber devices. According to the study, published in Pulmonary Therapy, use of the AEROCHAMBER PLUS® FLOW-VU® antistatic chamber resulted in delayed time to first exacerbation, fewer asthma-related emergency department visits, and lower exacerbation- Asthma is a common respiratory condition that affects an estimated 24.6 million people in the United States. Almost half of them, including nearly 3 million children, experience one or more asthma attack in a year. As opposed to systemic medications, inhalation is the recommended way to administer asthma medications because it directly targets the drug to the lungs while reducing potential side effects. Inhaled corticosteroids and bronchodilators administered by MDIs are the mainstay of long-term asthma treatment, the goals of which are to improve symptoms and prevent the occurrence of exacerbations. Poor inhaler operation by users is common, resulting in less of the delivered drug reaching the lungs. Instead, much of it is deposited on the back of the throat (oropharyngeal deposition) and then swallowed. Research shows that between 28% and 68% of patients do not use inhalers well enough to benefit from prescribed medication. In addition, 25% of costs associated with inhalers is wasted due to poor inhaler technique. Chambers are designed to reduce oropharyngeal deposition by changing the particle size distribution of the inhaled aerosol, and by holding the aerosol in the chamber until the patient is ready to inhale, which reduces the need for good coordination between inhalation and inhaler actuation. Effectiveness of these devices can be adversely affected by the design, including the chamber electrostatic charge, a commonly reported cause of inconsistent medication delivery. Global respiratory guidelines recommend the use of chambers to improve MDI drug delivery. American Thoracic Society and American Association for Respiratory Care Clinical Practice Guidelines state that the addition of a chamber is recommended and helpful. Research also indicates that patients who use a chamber with an MDI have better asthma control than those using an MDI alone. In this new study, Dr. Chakkarin Burudpakdee (QuintilesIMS, Fairfax, VA, USA) and colleagues compared the effects of the antistatic AEROCHAMBER PLUS® FLOW-VU® aVHC and control chambers on treatment outcomes, resource use, and healthcare costs in a real-world asthma population. More than 18,000 patients were included from an adjudicated claims database containing medical and pharmacy claims for more than 150 million U.S. health plan members. The analysis showed that among patients with at least 30 days of follow-up, those using the AEROCHAMBER PLUS® FLOW-VU® antistatic VHC experienced a delay in the time to first exacerbation and had fewer asthma-related emergency room visits. In addition, exacerbation- "This landmark study using a large volume of real-world evidence generated from thousands of patients shows the value of optimizing drug delivery in asthma management and further supports that chambers are not interchangeable," "The European Medicines Agency recommended in 2009 that development of a MDI should include the testing of at least one specific, named chamber, and that any substitution must be supported by appropriate in vitro or clinical data demonstrating equivalence," For clinical inquiries, please contact: Dominic P.
