Method for treating asthma using optically pure R(-) salmeterol

摘要

The optically pure R(-) isomer of salmeterol, which is substantially free of the S(+) isomer, is a potent bronchodilator for relieving the symptoms associated with asthma in individuals. A method is disclosed utilizing the optically pure R(-) isomer of salmeterol for treating asthma while minimizing toxicity and other side effects associated with salmeterol.
