Trying to find out if my meds are doing the same thing: Spiriva Handihaler, ProAir, Advair?

No, the medicines in Spiriva, ProAir and Advair all work differently.

Spiriva is an anticholinergic agent. It works by enlarging the airways to allow easier breathing. It is used to prevent bronchospasm (narrowing of the airways in the lungs) in people with bronchitis, emphysema, or COPD (chronic obstructive pulmonary disease).

ProAir HFA (albuterol) is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs. Albuterol inhalation is used to treat or prevent bronchospasm in people with reversible obstructive airway disease. It is also used to prevent exercise-induced bronchospasm.

Advair HFA contains fluticasone and salmeterol.

Fluticasone is a steroid. It prevents the release of substances in the body that cause inflammation. Salmeterol is a bronchodilator. It works by relaxing muscles in the airways to improve breathing.

Fluticasone and salmeterol inhalation is used to prevent asthma attacks. It is also used to prevent flare-ups or worsening of chronic obstructive pulmonary disease (COPD) associated with chronic bronchitis and/or emphysema.
