[Use of spasmolytic agent otilonium bromide (spasmomen) in digestive endoscopy: a prospective study in 63 patients].

Otilonium bromide is a calcium antagonist with a direct myolytic effect, that is indicated in spastic conditions and functional dyskinesias of the gastroenteric apparatus (irritable bowel syndrome) and as a premedication for gastrointestinal endoscopic procedures. The present study assessed otilonium bromide 40 mg PO the night before and 40 mg PO the morning in 49 upper and 14 lower flexible endoscopies in 63 patients, to determine the presence or absence of peristalsis and relaxation of the pylorus. No side effects were observed due to the medication. In 46 (93.8%) upper endoscopies marked relaxation of the gastrointestinal tract and also pylorus relaxation were observed. In 13 (92.8%) lower endoscopies, marked relaxation of the colonic tract was also seen. All patients tolerated well the endoscopies. Otilonium bromide was useful as premedication in order to enable upper and lower endoscopic explorations, because of its spasmolytic effect.
