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.. 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).. 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.. The effectiveness of famotidine and acotiamide combination therapy in FD was similar to the effectiveness of acotiamide therapy alone.

The aim of this study is to clarify whether acotiamide and rabeprazole combination therapy can improve clinical symptoms, gastric emptying, and satisfaction with treatment in functional dyspepsia (FD) patients more effectively than acotiamide or rabeprazole monotherapy alone. We also aimed to determine whether acotiamide affects these changes via its effect on gastric emptying and appetite-related hormones such as ghrelin.. We used Rome III criteria to evaluate upper abdominal symptoms and anxiety by the State-Trait Anxiety Inventory (STAI). Gastric motility was evaluated by the (13) C-acetate breath test. Eighty-one FD patients were treated with acotiamide (300 mg/day) (n = 35), acotiamide (300 mg/day) and rabeprazole (10 mg/day) (n = 28), or rabeprazole (10 mg/day) (n = 18) for a period of 4 weeks and followed after 4 weeks of no treatment. Adenocorticotropic hormone (ACTH), cortisol, leptin and ghrelin levels were measured in all FD patients.. Acotiamide and rabeprazole combination therapy significantly improved postprandial distress syndrome (PDS)-like symptoms (p = 0.018, p = 0.04 and p = 0.041, respectively) and epigastric pain (p = 0.024) as wells as STAI-state scores (p = 0.04) compared to rabeprazole monotherapy. Both acotiamide monotherapy, and acotiamide taken in combination with rabeprazole, significantly (p = 0.001 and p = 0.02, respectively) improved satisfaction with treatment, compared to rabeprazole monotherapy. Acotiamide and rabeprazole combination therapy had no significant effect on ACTH and cortisol levels in FD patients. Of interest, acotiamide monotherapy, and acotiamide and rabeprazole combination therapy, significantly (p < 0.0001 and p = 0.018, respectively) increased acylated ghrelin/total ghrelin ratios and significantly (p = 0.04) improved impaired gastric emptying compared to rabeprazole monotherapy.. Further studies are warranted to clarify how acotiamide treatment improves clinical symptoms in FD patients.

This long-term 48-week study of acotiamide was carried out to investigate the efficacy, safety and administration pattern in patients with functional dyspepsia (FD).. This was a multicenter, open-label, single-arm, long-term phase III study in which patients with FD were given acotiamide, 100 mg t.i.d., for 48 weeks. The two major efficacy endpoints were global overall treatment efficacy (OTE) and the elimination rate of three cardinal symptoms (i.e. postprandial fullness, early satiation and upper abdominal bloating), which were evaluated weekly and daily by the patients, respectively. The long-term administration patterns were investigated by following the patients based on cessation and readministration criteria.. Efficacy was analyzed in 405 patients. The OTE improvement rate was 26.1% at week 1 and increased with time. It was 60.6% at week 8 and subsequently maintained. Similarly, the symptom elimination rate increased up to week 8. Many patients who met the cessation criterion achieved remission of FD symptoms after experiencing dose interruption and readministration. The incidence rate of adverse drug reactions was 11.5% and most of the adverse drug reactions were mild in severity except increased ALT in 1 patient.. FD symptoms were controlled by intermittent administration of acotiamide even in patients with relapsing FD.

The aims of the study are to clarify the pathophysiological differences among early chronic pancreatitis (ECP), functional dyspepsia with pancreatic (FD-P) enzyme abnormalities and FD patients and to determine whether camostat mesilate, pancrelipase, and rabeprazole triple therapy improve FD symptoms in the ECP patients and FD-P patients in cross-over way.. We enrolled 84 consecutive patients presenting with typical symptoms of FD patients (n = 42), ECP patients (n = 15), and FD-P patients (n = 27). Gastric emptying was assessed by the 13C-acetate breath test. ECP was diagnosed based on the criteria recommended by the Japan Pancreatic Association.. The proportions of female in ECP patients and FD-P were significantly higher compared to that in FD patients. The early phase of gastric emptying in ECP and FD-P patients was significantly disturbed compared to that in FD patients. The primary outcome of this study is that 4 weeks of camostat mesilate, pancrelipase, and rabeprazole triple therapy significantly ameliorated epigastric pain in ECP patients compared to acotiamide and rabeprazole combination therapy.. Although there were no significant differences in pathophysiology between ECP patients and FD-P patients, triple therapy can significantly ameliorate epigastric pain in ECP patients. Further studies will be needed to clarify why triple therapy can improve epigastric pain in ECP patients.

The effect of acotiamide on gastrointestinal symptoms is undefined. The aim of this study is to evaluate the effect of acotiamide on abdominal symptoms in patients with functional dyspepsia. We retrospectively reviewed 51 patients treated with acotiamide. We evaluated patient quality of life using the Izumo scale that detects changes in quality of life caused by abdominal symptoms. Acotiamide ameliorated the symptoms of functional dyspepsia at one and three months (improved: 61% vs 80%, p=0.029 and resolved: 17% vs 33%, p=0.069). We then evaluated the effect of acotiamide on epigastric pain syndrome (EPS) (n=33) and postprandial distress syndrome (PDS) (n=41). Acotiamide treatment showed an early effect on rates of improvement (63%) and resolution (42%) of EPS symptoms at one month, maintained up to three months (69% and 39%, respectively). Both rates of improvement and resolution of PDS symptoms showed a significant increase from one month to three months (56% vs 78%, p=0.021 and 17% vs 46%, p=0.004, respectively). The severity of functional dyspepsia symptoms before treatment was significantly associated with failed resolution of functional dyspepsia symptoms (p=0.013). Acotiamide improves and resolves EPS symptoms as well as PDS symptoms. PDS symptoms take longer to resolve than EPS symptoms. J. Med. Invest. 63: 230-235, August, 2016.
