Although peripheral actions have been shown for the brain-gut peptide, motilin, its localization in the CNS of mammals suggests some physiological role at this site. In the present experiments intracerebroventricular or intrathecal, but not peripheral, administrations of motilin produced a dose-related and naloxone reversible inhibition of the micturition reflex. Cross-tolerance was demonstrated between motilin and morphine in this respect. These data suggest a physiological role for motilin within CNS to alter urinary bladder motility, possibly through an enkephalinergic or naloxone-sensitive link.
