Abstract

A large number of asthmatic individuals currently participate in sports events. Recent advances in the pharmacologic treatment of asthma are key factors allowing athletic participation of asthmatic individuals interested in sport and exercise. Of the many therapeutic agents available, the beta2 agonists are the drugs of choice for acute exacerbations of chronic asthma, for intermittent symptoms, and for protection from exercised-induced asthma. Inhalation of beta2 agonists is perferred for the treatment or prevention of bronchospasm. Beta2 agonist aerosols are generally administered by metered dose inhaler (MDI). Many asthmatics utilize MDIs improperly. This is a significant problem, since technique is the major determinant of the dose delivered to the lung. Proper use of these aerosols may increase the likelihood that the asthmatic athlete can participate safely and competitively. Athletic trainers can play a key role in assuring that asthmatic athletes are knowledgeable about their medications and their proper use. This paper briefly reviews the pharmacology, adverse effects, proper use, and banned drug status of the beta2 agonist aerosols. Verf.-Referat
