Abstract

The effects on gastric emptying of a solid meal of the specific 5-HT3-receptor antagonist ICS 205-930, 10 mg and 20 mg intravenously were assessed with a scintigraphic technique in 12 normals. The 50% emptying time was less, the lag phase was shorter and the post lag emptying rate was faster after 20 mg ICS 205-930 (p less than 0.02). After 10 mg ICS 205-930 the lag phase was significantly shorter compared with placebo (p less than 0.04). These results suggest that 5-HT3 receptors may be involved in the regulation of gastric emptying in man.

摘要

采用闪烁扫描技术,在12名正常人中评估了静脉注射10毫克和20毫克特异性5-羟色胺3(5-HT3)受体拮抗剂ICS 205-930对固体食物胃排空的影响。注射20毫克ICS 205-930后,50%排空时间缩短,延迟期缩短,延迟后排空速率加快(p<0.02)。注射10毫克ICS 205-930后,与安慰剂相比,延迟期显著缩短(p<0.04)。这些结果表明,5-HT3受体可能参与人体胃排空的调节。
