Stiolto active ingredients?

What are the active ingredients in Stiolto?

Stiolto is a chronic obstructive pulmonary disease (COPD) inhaler that contains two active ingredients: tiotropium and olodaterol. [1]

What do tiotropium and olodaterol do in the inhaler?

Tiotropium is a long-acting antimuscarinic (LAMA). It helps relax the airway muscles by blocking muscarinic receptors, which can reduce bronchoconstriction. [1]
Olodaterol is a long-acting beta2-agonist (LABA). It relaxes airway smooth muscle by stimulating beta2 receptors. [1]

Why is Stiolto a “two-drug” COPD inhaler?

Stiolto combines a LAMA (tiotropium) and a LABA (olodaterol) to provide bronchodilation through two different mechanisms, aimed at improving airflow and helping manage COPD symptoms. [1]

Are the active ingredients different from other COPD inhalers?

Yes. Many COPD inhalers use one long-acting bronchodilator (either LAMA or LABA) or different combinations. The defining feature of Stiolto is that it specifically pairs tiotropium + olodaterol. [1]
