A common asthma drug used in inhalers may actually worsen the health of some patients, while showing limited beneficial effects for children. A study performed in Great Britain found that salbutamol (called albuterol in the United States)and salmeterol may worsen the health of patients with a specific gene variant.
The study showed that asthma patients using an inhaler daily who carry the gene variant were 30 percent more likely to have asthma attacks compared with those with the more usual form of the gene.
The study is published in the American Academy of Allergy, Asthma and Immunology.
