I was wondering if anyone can tell a difference between these two meds? When Xopenex was first released it was suppose to be superior to albuterol because it supposedly had few side effects such as not raising the HR like albuterol can. But now the resp therapists are telling me that Xopenex is not superior to albuterol and that Medicare will not pay for Xopenex....Some of the docs think Xopenex is better and others still go with albuterol. I really haven't been able to tell a difference between the two....anyone else with any opinions on this topic?
