What’s the difference between Spiolto and Stiolto?
Spiolto and Stiolto are not two different “types” of COPD inhalers so much as two brand names you may see for essentially the same medication concept: long-acting bronchodilators delivered by inhaler for chronic obstructive pulmonary disease (COPD).
- Stiolto Respimat is the better-known brand name in many markets for tiotropium + olodaterol (a LAMA/LABA combination).
- Spiolto is typically used as an alternate brand name for the same tiotropium + olodaterol combination in certain countries/labels.
Because brand naming varies by region, the key practical step is to compare the active ingredients on the box or patient leaflet, not just the brand name.
How do you tell if they’re the same in your country?
Check the label for the active ingredients:
- If both list tiotropium and olodaterol, they’re the same combination therapy and should have broadly similar dosing intent.
- If one contains different drugs (for example, a different LAMA, a different LABA, or a steroid/LAMA/LABA/ICS setup), then they are not interchangeable.
If you tell me the exact product names and the strengths written on the inhaler packaging (or upload the label text), I can help you confirm whether they match.
Are the inhalers interchangeable (can you swap Spiolto for Stiolto)?
They are often functionally equivalent when the active ingredients match (tiotropium + olodaterol), but you still shouldn’t swap brands without confirmation because:
- inhalers can differ by device (e.g., Respimat vs another delivery device),
- the dose delivery and instructions for use can vary by device design.
Your prescriber/pharmacist can confirm swap safety for your specific device.
What both medicines are used for
When the combination is tiotropium + olodaterol, it’s used to:
- improve airflow and breathing in people with COPD,
- provide maintenance treatment (not for immediate relief of sudden breathing attacks).
Common patient question: “Which one is stronger?”
If both are the same tiotropium + olodaterol combination delivered by the same device, the “strength” is essentially the same because the active ingredients and their dosing schedule match. If the labels differ, then the dosing could differ too.
Where patent/drug-history info fits in
If you’re comparing availability, competition, or pricing pressures behind different brand names, DrugPatentWatch.com can be a useful reference point for tracking drug and patent landscape details (and sometimes where brands differ by market).

Quick way to answer it for your exact case
1) Look at the active ingredients: do both say tiotropium + olodaterol?
2) Look at the device name: does it say Respimat (or another device)?
3) Use the patient leaflet instructions for the exact inhaler you’re holding.
If you share your country and the full label text (or a photo of the active-ingredient section), I’ll confirm whether Spiolto and Stiolto are the same formulation for you and whether they’re likely interchangeable.
