Tiotropium is a long-acting muscarinic antagonist (LAMA) used to treat chronic obstructive pulmonary disease (COPD) and sometimes asthma. It helps by relaxing airway muscles and reducing bronchoconstriction, making it easier to breathe. Tiotropium is available in inhalation powder (Spiriva HandiHaler) and soft mist inhaler (Spiriva Respimat) formulations, providing once-daily bronchodilation for long-term symptom management.

Tiotropium is a LAMA (Long-Acting Muscarinic Antagonist). It blocks muscarinic receptors, leading to bronchodilation, whereas LABAs (Long-Acting Beta Agonists) stimulate beta receptors to achieve a similar effect.
Tiotropium belongs to the anticholinergic drug class, specifically long-acting muscarinic antagonists (LAMAs).
No, Tiotropium and Ipratropium are different:
Yes, Tiotropium is a muscarinic antagonist, meaning it blocks muscarinic (M3) receptors in the lungs to prevent bronchoconstriction and improve airflow.
