title: Effects of proglumide on pancreatic endocrine and exocrine function in healthy humans.
abstract: A comparative study was done on the pancreatic endocrine (insulin (IRI), human pancreatic polypeptide (hPP] and exocrine secretion (fluid volume, amylase output, bicarbonate output), before and after administration of proglumide. At the time of the test meal loading, plasma hPP and cholecystokinin (CCK) were also measured. During continuous i.v. administration of proglumide 750 mg and 1650 mg/h 30 min before CCK-8 (20 ng/kg) stimulation, no significant difference in the rise of plasma hPP level was observed, as compared with a single stimulus of CCK-8, nor were there any significant differences in the exocrine secretion. The values of hPP and CCK-8 under a load of test meal significantly elevated after a food load. Although hPP showed a significant inhibition with the administration of proglumide 1650 mg/h, plasma CCK-8 and blood sugar levels were not significantly different from control groups. Therefore, while proglumide has a very weak effect on the action of pancreatic endocrine function, it does have an inhibitory effect on pancreatic function, during physiological stimulation.
