Spiriva vs. ProAir

See how Spiriva and ProAir compare on approved uses, dosing, side effects, and cost.

Key Takeaways

  • Spiriva is a once-daily maintenance inhaler for COPD and asthma, while ProAir is a fast-acting rescue inhaler used for sudden bronchospasm or before exercise.

  • These drugs treat breathing problems differently and are commonly used together rather than as substitutes for each other.

  • Spiriva must never be used for a sudden asthma or COPD attack, and ProAir is not meant to control symptoms over the long term.

Spiriva vs. ProAir Drug Summary

Spiriva

Spiriva (tiotropium) is a long-acting muscarinic antagonist inhaler used for daily maintenance treatment of COPD, and with the Respimat device, for asthma in people 6 and older. It is taken once a day to keep airways open and lower the risk of flare-ups over time.

ProAir

ProAir (albuterol) is a short-acting beta agonist inhaler used to treat or prevent sudden bronchospasm, including symptoms triggered by exercise. It works within minutes and is taken as needed rather than on a fixed daily schedule.

Spiriva vs. ProAir Indications

Spiriva

Spiriva is FDA-approved for long-term maintenance treatment of COPD, including chronic bronchitis and emphysema, and for reducing COPD exacerbations. The Respimat version is also approved for long-term asthma maintenance in patients 6 and older. It is not approved to relieve a sudden asthma or COPD attack.

  • Long-term maintenance treatment of COPD

  • Reduces COPD exacerbations

  • Long-term asthma maintenance (Respimat, ages 6+)

  • Not for acute bronchospasm or asthma attacks

ProAir

ProAir is FDA-approved to treat or prevent bronchospasm in people with reversible obstructive airway disease, including asthma, starting at age 4. It is also approved to prevent bronchospasm brought on by exercise. It is not approved for stopping preterm labor.

  • Treats sudden bronchospasm (ages 4+)

  • Prevents bronchospasm in reversible airway disease

  • Prevents exercise-induced bronchospasm

  • Not approved as a tocolytic for preterm labor

Spiriva vs. ProAir Pros and Cons

Spiriva

Spiriva provides steady, once-daily airway control and lowers the frequency of COPD flare-ups, but it does not act fast enough for sudden symptoms. It carries a higher list price than rescue inhalers and needs careful use in people with glaucoma or urinary retention.

Pros

  • Only needs to be taken once a day

  • Approved to reduce COPD exacerbations over time

  • Available in two devices (HandiHaler and Respimat) covering COPD and asthma

  • Decades of clinical use behind its safety profile

Cons

  • Not a rescue medication for sudden symptoms

  • Roughly $600 to $630 per month without insurance, before savings programs

  • May worsen narrow-angle glaucoma or urinary retention

  • Requires a separate rescue inhaler for emergencies

ProAir

ProAir works within minutes to relieve sudden bronchospasm and is far less expensive than a daily maintenance inhaler, but its effects wear off quickly. Using it more often than prescribed can signal that asthma or COPD is not well controlled.

Pros

  • Works within minutes for sudden symptoms

  • Roughly $85 to $95 per month without insurance, before savings programs

  • Comes with a built-in dose counter

  • Approved to prevent exercise-induced bronchospasm

Cons

  • Effects wear off within a few hours

  • Can cause tachycardia and other cardiovascular effects

  • Not intended for long-term daily control

  • Overuse can mask worsening disease
