Definition:A quaternary ammonium ion obtained by methylation of the tertiary amino group of (1alpha,2beta,4beta,5alpha,7beta)-7-[(hydroxydi-2-thienylacetyl)oxy]-9-methyl-3-oxa-9-azoniatricyclo[,4)]nonane. Used (in the form of the bromide hydrate) for maintenance treatment of airflow obstruction in patients with chronic obstructive pulmonary disease.
