Effect of cisapride on gastric and esophageal emptying in insulin-dependent diabetes mellitus.
The effects of cisapride on gastric emptying, esophageal emptying, gastrointestinal symptoms, and glycemic control were evaluated in 20 insulin-dependent diabetics who had delayed gastric emptying of the solid or liquid component of a meal, or both. A double-isotope technique was used to measure gastric emptying, and esophageal emptying was measured as the time for a bolus of the solid meal to enter the stomach. On 2 days each patient received cisapride (20 mg) or placebo orally, 60 min before an esophageal and gastric emptying test. A third gastric and esophageal emptying test was performed after each patient had orally taken 10 mg of cisapride or placebo q.i.d. for 4 wk. Single-dose cisapride increased esophageal emptying (p less than 0.01) and both solid and liquid gastric emptying (p less than 0.001). The response to cisapride was most marked in patients with the greatest delay in esophageal and gastric emptying (p less than 0.05). After administration of cisapride for 4 wk, gastric emptying of solid and liquid were faster (p less than 0.001), but esophageal emptying was not significantly different from the placebo test. Upper gastrointestinal symptoms were less after cisapride (p less than 0.05), whereas there was no change on placebo (p greater than 0.2). Plasma glucose and glycosylated hemoglobin concentrations were not different after cisapride compared with placebo. These results indicate that single-dose cisapride increases esophageal emptying in insulin-dependent diabetics and that chronic administration of cisapride is effective in the treatment of diabetic gastroparesis.
