NCIt related terms : TIOTROPIUM BROMIDE ANHYDROUS;
NCIt definition : The bromide salt form of tiotropium, a quaternary ammonium derivative of atropine
and a muscarinic receptor antagonist, with bronchodilating activity. Although it does
not display selectivity for specific muscarinic receptors, on topical application,
tiotropium bromide acts mainly on M3 muscarinic receptors located on smooth muscle
cells and submucosal glands, preventing smooth muscle contraction and mucus secretion,
thus producing a bronchodilatory effect.;
