Question

Quizplus · Accepted Answer

Albuterol is composed of both (R)- and (S)-isomers of albuterol. Levalbuterol is the active isomer of albuterol (R-albuterol) and is indicated for the treatment or prevention of bronchospasms in adults and children. In studies of asthma treatment in the pediatric patient, levalbuterol has been compared with both racemic albuterol and placebo. In doses of 0.31 and 0.63 mg, levalbuterol produced an equipotent degree of bronchodilation, as measured by percent change from predose forced expiratory volume at 1 second (FEV₁), as comparable doses of 1.25 and 2.5 mg of racemic albuterol. This same study found that 0.63 mg of levalbuterol was equipotent to 1.25 mg of racemic albuterol, and 1.25 mg of levalbuterol was equipotent to 2.5 mg of racemic albuterol.
