  Would help more if you would of paint the complete pic that been preached.

Anyhow, we use B2 selectivity/albuterol* bz few CV SE than /B1 side effects ( tachy for one cardiac ischemia/dysrhyth… so less harm to those with CAD) than nonselective B agents like Epi ( carries more B1 & alpha SE) especially with no care when u adm more dose. So, more SE & not being selective for lower airways B2/agonists*.

  I assume its because there is no use of alpha receptors functions in asthma. If it were for anaphylaxis, epi is good as it has both alpha and beta effect but in asthma we need only beta. Its just my assumption though.

  @Cardio69 and @750ok, Thank you so much for addressing it. It makes sense now. Since Epi has both alpha and Beta actions (non selectivity)-- more SE-- Less useful.
I thought, to contraindicate a drug here, there should be something terrible happening here if we give Epi in Asthma patients.

  You would still give epi to an asthmatic pt if an anaphylactic episode
