Background/aims: Acotiamide, a prokinetic drug, is used to treat functional dyspepsia (FD), especially postprandial distress syndrome (PDS). However, a treatment for FD patients with PDS and/or epigastric pain syndrome (EPS) has not been established. We investigated the efficacy of famotidine in combination with acotiamide for FD.
Methods: Fifty blindly randomized FD patients received placebo with acotiamide, or famotidine with acotiamide, for 4 weeks. Treatment efficacy was assessed by overall treatment effects (OTE), total, PDS and EPS symptom scores, and impairment of quality of life (QOL).
Results: After OTE assessment, patients who felt affected by treatment comprised 40.9 and 57.9% of famotidine and placebo groups, respectively, after 4 weeks' treatment, with no significant difference between groups. A significant decrease was seen in total, PDS, and EPS symptom scores, and in QOL impairment, after 4 weeks' treatment compared with pretreatment scores for famotidine and placebo groups, but was not observed between groups. The proportion of patients showing a ≥50% decrease in EPS symptom scores was greater in the famotidine than that in the placebo group for every observation point, with the greatest difference observed after 2 weeks' treatment.
Conclusion: The effectiveness of famotidine and acotiamide combination therapy in FD was similar to the effectiveness of acotiamide therapy alone.
