Clinical trial: dose-dependent therapeutic efficacy of acotiamide hydrochloride (Z-338) in patients with functional dyspepsia - 100 mg t.i.d. is an optimal dosage.

| Abstract | BACKGROUND:
Acotiamide is a selective acetylcholinesterase inhibitor and enhances the actions of cholinergic neurons localized in the stomach. METHODS: The present two studies were conducted to examine the optimal dosage of acotiamide hydrochloride (Z-338) in patients with functional dyspepsia (FD) in Japan. KEY RESULTS: The improvement rate of 'subjects global assessment of overall treatment efficacy (OTE)' at the final evaluation was approximately 10% higher in the acotiamide 100 mg group than that in the placebo group with good reproducibility though there was no significant differences at primary endpoint. The elimination rate of postprandial fullness in the acotiamide 100 mg group was significantly higher compared to placebo group. In addition, the post hoc analysis showed that in patients whose main complaints are meal-related symptoms such as postprandial fullness, upper abdominal bloating and/or early satiety, the improvement rate of 'OTE' at final evaluation in acotiamide 100 mg group was significantly superior to that in the placebo group. CONCLUSIONS & INFERENCES: These results suggest that acotiamide possesses efficacy on FD and more specifically its meal-related symptoms of FD.
