title: Effect of antispasmodic drugs on the colonic motility. Part II: Clinical study in man.
abstract: Four antispasmodic preparations (prifinium bromide, propinox, trimebutine maleate and phloroglucinol + trimethylphloroglucinol) identical to those in Part I, study of the dog, were used. Eight subjects were tested for each preparation and eight subjects for the control. The inhibitory effect of the test preparations on neostigmine-induced hypermotility of the ascending and sigmoid colons were investigated. Prifinium bromide provided a marked antispasmodic effect on the ascending and sigmoid colons; the inhibitory effect of trimebutine maleate was limited to the ascending colon. Propinox and phloroglucinol + trimethylphloroglucinol possessed no clear action. It is estimated that prifinium bromide may be useful in the control of the manifestic state of hypermotility of the colon.
