Ipratropium. blocks transmission. have a delayed (>30 min) onset of action. are second line drugs \u2013 used as an adjunct to \uf0622-adrenoceptor agonists and glucocorticosteroids. relax bronchospasm caused by irritant stimuli (irritants initiate a vagal reflex that liberates ACh) decrease mucus secretion. have no effect on the late inflammatory stage. have few adverse effects. more effective agents (e.g. tiotropium) with selectivity for M3 muscarinic receptors have recently been introduced.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
