摘　　要：AIM： Itopride is a newly developed prokinetic agent, which enhances gastric motility through both antidopaminergic and anti-acetylcholinesterasic actions. The importance of esophageal motor dysfunction in the pathogenesis of gastro-esophageal reflux disease （GERD） makes it interesting to examine the effect of itopride on esophageal acid exposure.METHODS： The effect of itopride on esophageal acid reflux variables for 24 h was studied in 26 patients with GERD symptoms, pre-entry total acid exposure time （pH〈4） of more than 5% and mild esophagitis （SavaryMiller grades I, II） proven by endoscopy. Ambulatory 24hpH-metry and symptom assessment were performed after treatments with 150 or 300 mg itopride thrice a day （t.i.d.） for 30 d in random order, using an open label method.For evaluating the safety of itopride, blood biochemical laboratory test was performed and the serum prolactin level was also examined before and after treatment.RESULTS： Total symptom score was significantly decreased after treatment in 150- or 300-mg group. Itopride 300 mg was significantly effective than 150 mg on decreasing the total per cent time with pH〈4, total time with pH〈4 and DeMeester score. No serious adverse effects were observed with administration of itopride in both groups.CONCLUSION： Itopride 100 mg t.i.d, is effective on decreasing pathologic reflux in patient with GERD and therefore it has the potential to be effective in the treatment of this disease.AIM: Itopride is a newly developed prokinetic agent, which enhances gastric motility through both antidopaminergic and anti-acetylcholinesterasic actions.
