    Abstract:
    INTRODUCTION AND AIM: To examine the involvement of cholecystokinin (CCK) in the basal pancreatic exocrine, we investigated the effect of loxiglumide (CR1505), a CCK1 receptor antagonist, on basal pancreatic exocrine secretion in conscious rats. METHODOLOGY: After the basal collection of pancreatic juice for 1 hour, loxiglumide (10 mg/kg/h) or saline was infused via the femoral vein continuously for 2 hours. RESULTS: Loxiglumide significantly suppressed the basal pancreatic protein and amylase outputs. However, loxiglumide did not alter the basal pancreatic juice volume. CONCLUSIONS: These results demonstrate that loxiglumide suppresses basal pancreatic exocrine secretion in normal rats. They also suggest that CCK is involved in basal pancreatic exocrine in conscious rats and that loxiglumide may be useful as a therapeutic agent for pancreatitis, even during fasting, by attenuating the basal pancreatic exocrine burden on the pancreas.
