The role of alcohol in asthma: A review of clinical and experimental studies

Asthma is among the most common ED diagnoses. Asthma exacerbations are gene rally treated by medications that cause bronchodilation and those that redu ce airway inflammation. The effect of alcohol on asthma has been studied by investigators with mixed results. Some studies have reported that alcohol has a beneficial effect on asthma; others report worsening of symptoms. It has been suggested in some quarters that additives in alcoholic drinks caus e bronchoconstriction and that pure ethanol has a salutary effect on asthma . If further research bears out this supposition, ethanol may play a limite d therapeutic role in asthma that is refractory to other therapy. Emergency physicians should counsel asthmatic patients to avoid alcoholic beverages because they may cause an exacerbation of asthma. Copyright (C) 2001 by W.B . Saunders Company.
