| Popis: | The efficacy of proton pump inhibitor therapy for symptom resolution in patients with functional dyspepsia remains controversial. This study was designed to compare the efficacy of lansoprazole with placebo in relieving upper abdominal discomfort in patients with functional dyspepsia.We enrolled 921 patients with functional dyspepsia (defined as persistent or recurrent upper abdominal discomfort during the prior 3 months) and moderate upper abdominal discomfort on at least 30% of screening days; none of the patients had predominant symptoms suggestive of gastroesophageal reflux or endoscopic evidence of erosive or ulcerative esophagitis, or gastric or duodenal ulcer or erosion. Patients were assigned randomly to receive lansoprazole 15 mg (n = 305), lansoprazole 30 mg (n = 308), or placebo (n = 308) daily for 8 weeks. Patients recorded the frequency and severity of symptoms in daily diaries.At week 8, significantly (P0.001) greater mean reductions in the percentage of days with upper abdominal discomfort were reported in patients treated with lansoprazole 15 mg (35%) or 30 mg (34%) compared with those treated with placebo (19%). Similarly, more patients treated with lansoprazole 15 mg (44%) or 30 mg (44%) reported complete symptom resolution (defined as no episodes of upper abdominal discomfort in the 3 days before the study visit) at 8 weeks than did placebo-treated patients (29%, P0.001). Improvement of upper abdominal discomfort, however, was seen only in patients who had at least some symptoms of heartburn at enrollment.Lansoprazole, at a daily dose of 15 mg or 30 mg, is significantly better than placebo in reducing symptoms of persistent or recurrent upper abdominal discomfort accompanied by at least some symptoms of heartburn. |
