Definition:The ester resulting from formal condensation of benzilic acid and 3-hydroxy-1-methyl-1-azoniabicyclo[2.2.2]octane. It is used, generally as the bromide, for the symptomatic treatment of peptic ulcer disease and also to help relieve abdominal or stomach spasms or cramps due to colicky abdominal pain, diverticulitis, and irritable bowel syndrome.
