Beta2-Agonists for Chronic Obstructive Pulmonary Disease (COPD)
While short-acting beta2-agonists may be the first choice for treating symptoms of mild COPD that come and go (intermittent symptoms), anticholinergics generally are regarded as the first-line treatment for persistent symptoms, in most cases of COPD.
Inhalation is the preferred method of taking beta2-agonists. This method reduces the chance of side effects and makes the medicine more effective. Pills and injections are reserved for those who cannot use a metered-dose inhaler (MDI) or nebulizer.
Nebulizers normally are no better at delivering beta2-agonists deep into the lungs than a properly used metered-dose inhaler. Sometimes your doctor may prescribe a nebulizer. Although a nebulizer can deliver a very large dose of medicine, it also may increase side effects of the medicine.
Most doctors recommend that everyone using an
inhaler also use a
spacer 
. Use of a spacer is especially important when
using an inhaler containing a steroid medicine. But you should not use a dry
powder inhaler (DPI) with a spacer.
