Maintenance bronchodilator treatments of chronic obstructive pulmonary disease (COPD) include oral inhaled long-acting muscarinic antagonists (LAMAs) and long-acting β2-agonists (LABA). These agents attenuate COPD symptoms and decrease the severity/number of exacerbations. They also enhance quality of life and heighten exercise capacity.
Tiotropium is a LAMA and anticholinergic, with similar degrees of affinity to M1 to M5 subtypes of muscarinic receptors. At the level of the airways, this agent inhibits M3-receptors at the smooth muscle, thus resulting in bronchodilation. In in vitro and in vivo studies, prevention of methacholine-induced bronchoconstriction effects lasted greater than 24 hours and were dose-dependent, with bronchodilation being mostly site specific. In clinical trials, handheld LAMA inhalers exhibited peak efficacy within 3 hours after the first dose.
What has your clinical experience been with LAMA inhalers? What is patient satisfaction regarding treatment?

Michael Evans4yrI dont manage the use of these as an ED physician but have found those on them in the community are managed quite well in terms of need for repeat Show More -
Eldridge Burns4yrLots of success with them provided the patients start using before late stage is extremely important that the patients know how to use the inhalers properly - there Show More
