The effect of two different single oral doses of loxiglumide (CR 1505, CAS 107097-80-3) on gall-bladder emptying induced by a 550-cal standard mixed meal in 6 healthy volunteers was studied. Following placebo, the maximal gall-bladder emptying occurred about 90 min after the meal (minimal residual gall-bladder volume 27.4% of basal volume). Loxiglumide 400 or 800 mg dose-dependently inhibited the physiologica gall-bladder emptying. Loxiglumide plasma levels dose-dependently increased. The inhibition of gall-bladder emptying and the kinetic of loxiglumide plasma levels were temporally related. The results of the present study confirm that oral loxiglumide is a potent orally active cholecystokinin (CCK) antagonist in man and that CCK is the major physiological mediator of gallbladder emptying in response to meal.

D008297 Male Males
D011377 Proglumide A drug that exerts an inhibitory effect on gastric secretion and reduces gastrointestinal motility. It is used clinically in the drug therapy of gastrointestinal ulcers. Xylamide,Milid,Xilamide
D002766 Cholecystokinin A peptide, of about 33 amino acids, secreted by the upper INTESTINAL MUCOSA and also found in the central nervous system. It causes gallbladder contraction, release of pancreatic exocrine (or digestive) enzymes, and affects other gastrointestinal functions. Cholecystokinin may be the mediator of satiety.

D005704 Gallbladder A storage reservoir for BILE secretion. Gallbladder allows the delivery of bile acids at a high concentration and in a controlled manner, via the CYSTIC DUCT to the DUODENUM, for degradation of dietary lipid. Gallbladders

D016473 Gallbladder Emptying A process whereby bile is delivered from the gallbladder into the duodenum. The emptying is caused by both contraction of the gallbladder and relaxation of the sphincter mechanism at the choledochal terminus.
