title: Caerulein in the treatment of biliary and renal colic.
abstract: A randomized controlled study has been carried out in order to check the activity of caerulein in the treatment of biliary and renal colic. In 88% out of 107 patients caerulein, 1 ng/kg IV, relieved biliary colic and had no side effects. To elucidate the mechanism of action of the peptide, 22 cholecystectomized patients, showing a dilation of the common bile duct (CBD), were submitted to caerulein treatment under echo-control. Reduction of CBD caliber was noticed when the dilatation was due to functional obstruction, whereas an organic obstruction of the terminal tract of CBD was found in the non-responding patients. Caerulein appears to be an effective agent in relieving biliary colic through a relaxation of Oddi's sphincter, and may be used in ultrasound differential diagnostics of terminal bile duct obstruction. Caerulein, 75 ng/kg intramuscularly, relieved renal colic in 75% of the examined patients; it is suggested that the effect of caerulein in this syndrome is due to central analgesic action.
