SPIRIVA® Respimat® Mode of Action

SPIRIVA® Respimat® is a long-acting, anticholinergic agent. It exhibits pharmacological effects through inhibition of M3-receptors.

This short animated video shows the mode of action (MoA) of SPIRIVA® (tiotropium) Respimat® in the treatment of asthma. Binding to M3 receptors, SPIRIVA® Respimat® blocks acetylcholine, which plays a significant role in the pathophysiology of asthma, and so alleviates bronchoconstriction.
