Tiovair Rotacaps 18mcg (1 Box = 3 Strips) (1 Strip = 10 Capsules)

Tiotropium is a long-acting, antimuscarinic agent, which is often referred to as an anticholinergic. It has similar affinity to the subtypes of muscarinic receptors, M1 to M5. In the airways, it exhibits pharmacological effects through inhibition of M3-receptors at the smooth muscle leading to bronchodilation. The effect was dose dependent and lasted longer than 24h. The long duration is probably due to the very slow dissociation from the M3 receptor. The bronchodilation following inhalation of tiotropium is predominantly a site-specific effect.
