How Different Beta-2 Receptor Genotypes Affect an Asthmatic's Response to Regular Salmeterol Treatment

Summary

The purpose of the study is to find out how well a long-acting beta agonist like salmeterol works in people with different forms of the same gene. Our hypothesis is that asthmatics with the Arg/Arg genotype will have loss of bronchoprotection against exercise-induced asthma with regular salmeterol treatment, as compared to asthmatics with the Gly/Gly genotype.
