Alternative mechanisms for tiotropium
2009
Tiotropium is commonly used in the treatment of chronic obstructive pulmonary disease. Although largely considered to be a long-acting bronchodilator, its demonstrated efficacy in reducing the frequency of exacerbations and preliminary evidence from early studies indicating that it might slow the rate of decline in lung function suggested mechanisms of action in addition to simple bronchodilation. This hypothesis was examined in the recently published UPLIFT study and, although spirometric and other clinical benefits of tiotropium treatment extended to four years, the rate of decline in lung function did not appear to be reduced by the addition of tiotropium in this study. This article summ…
The pharmacological rationale for combining muscarinic receptor antagonists and beta-adrenoceptor agonists in the treatment of airway and bladder dis…

Highlights • Muscarinic receptors increase smooth muscle tone in airways and urinary bladder. • β-Adrenoceptors relax smooth muscle tone and oppose muscarinic contraction. • Opposition involves transmitter release, signal transduction and receptor expression. • This supports the combined use of muscarinic antagonists and β-adrenoceptor agonists.
