NCIt definition : An orally available bromide salt form of butylscopolamine, a quaternary ammonium derivative
of the alkaloid scopolamine, with anticholinergic property. Upon oral administration,
hyoscine butylbromide binds to and blocks muscarinic receptors located on postganglionic
parasympathetic nerve endings and on smooth muscle cells. This blocks the activity
of acetylcholine (Ach) and causes its antispasmodic effect in the gastrointestinal
(GI), urinary, uterine, and biliary tracts. This agent may also facilitate radiologic
visualization of the GI tract.;
