What is the drug class of Spiriva?

Spiriva, known generically as tiotropium, belongs to the antiasthmatic drug class as it is primarily used for the management of chronic obstructive pulmonary disease (COPD) and asthma. It functions as a long-acting muscarinic antagonist (LAMA), helping to relax the muscles around the airways and improve breathing by dilating the air passages in the lungs. This action makes it effective in managing respiratory conditions characterized by bronchoconstriction, which aligns with its categorization as an antiasthmatic medication.

The other classifications do not apply to Spiriva. Antidepressants are used for treating mood disorders, antihypertensives target high blood pressure, and opioid analgesics are used for pain management. Spiriva’s specific mechanism of action and therapeutic use distinctly align it with the antiasthmatic drug class, emphasizing its role in respiratory health.
