Some drugs regularly used in the treatment of asthma (beta-agonists and corticosteroids) are registered on the list of drugs forbidden in sport, because they have a doping action. To avoid penalizing asthmatic sportsmen, some beta-agonists (Salbutamol, Salmeterol, Terbutaline) and corticosteroids are allowed only in inhaled form, with written notification from the prescribing physician, a pneumologist or the team doctor. Considering the increase of doping with increasing involvement of physicians, good and up to date notions about the current rules of prescription in asthmatic sportsmen are needed.
