Abstrakt: Saline or loxiglumide (2.5 mg kg-1 in 10 min, followed by 5 mg kg-1 h-1 for 200 min) was administered intravenously in random order to six healthy subjects. After 60 min cholecystokinin (CCK-33) was infused (0.5 i.d.u. kg-1 h-1 for 1 h then 1.0 i.d.u. kg-1 h-1 for 1 h). Loxiglumide did not change basal levels of CCK and did not augment plasma CCK-immunoreactivity during CCK-33 infusion. After cessation of the CCK-infusion, plasma CCK concentrations decreased rapidly to basal values within 12 min, and the elimination half-life during loxiglumide infusion (4.8 +/− 0.8 min) was not significantly different from that during saline infusion (4.2 +/− 1.0 min). These results suggest that loxiglumide does not interfere with the distribution and metabolism of CCK. [ABSTRACT FROM AUTHOR]
