Thus, physicians worldwide regularly prescribe several anticholinergic agents, including atropine, ipratropium bromide, thiazinamium, oxitropium bromide, and glycopyrrolate. Of these, ipratropium bromide is the most widely studied. Nevertheless, the role for anticholinergic medications is less well-defined for patients with acute asthma.
