Tiotropium Bromide

Tiotropium bromide is a long-acting, 24-hour, anticholinergic bronchodilator used in the management of chronic obstructive pulmonary disease (COPD). Tiotropium is a muscarinic receptor antagonist, often referred to as an antimuscarinic or anticholinergic agent. Although it does not display selectivity for specific muscarinic receptors, when topically applied it acts mainly on M3 muscarinic receptors[7] located on smooth muscle cells and submucosal glands. This leads to a reduction in smooth muscle contraction and mucus secretion and thus produces a bronchodilatory effect.
