Most acute wheezing episodes in preschool children lead to airway dehydration. Together with other factors, airway dehydration causes the body to have trouble clearing mucus. These children do not respond well to available treatments. A new study published in the journal Pediatrics evaluated the effect of administering inhaled hypertonic saline to wheezing preschool children, which promotes airway hydration and thus mucus clearance [1].
FDA Removing Over-the-counter Asthma Drug From Shelves for Environment
September 30, 2011 | by
Users of Primatene Mist, the only over-the-counter treatment for acute symptoms of asthma, will need to find an alternative as of December 31, 2011. The U.S. Food and Drug Administration (FDA) recently announced that the medication will no longer be available because it uses chlorofluorocarbons (CFCs) as a propellant agent [1], and CFCs have long been known to deplete Earth’s ozone layer.
Clearing Up Concerns Over Vicks VapoRub
February 6, 2009 | by
A new study raised concerns recently over safety of the popular ointment Vicks VapoRub in young children. Wake Forest University researchers report that the salve, which is used to relieve symptoms of cough and chest congestion, may actually stimulate mucus production and airway inflammation in infants and toddlers [1]. However, the results are far from conclusive as the study was based on the case of a single child and 15 animals. Moreover, many of the results of the study have been incorrectly reported by the media.
