A peripheral acetylcholinesterase (AChE) inhibitor used to treat functional dyspepsia.
Acotiamide hydrochloride (acotiamide; N-[2-[bis(1-methylethyl) amino]ethyl]-2-[(2-hydroxy-4,5-dimethoxybenzoyl) amino] thiazole-4-carboxamide monohydrochloride trihydrate, Z-338) has been reported to improve meal-related symptoms of functional dyspepsia in clinical studies.
Acotiamide (Acofide(®)), an oral first-in-class prokinetic drug, is under global development by Zeria Pharmaceutical Co. Ltd and Astellas Pharma Inc. for the treatment of patients with functional dyspepsia. The drug modulates upper gastrointestinal motility to alleviate abdominal symptoms resulting from hypomotility and delayed gastric emptying. It exerts its activity in the stomach via muscarinic receptor inhibition, resulting in enhanced acetylcholine release and inhibition of acetylcholinesterase activity. Unlike other prokinetic drugs that are utilized in the management of functional dyspepsia, acotiamide shows little/no affinity for serotonin or dopamine D2 receptors. Acotiamide is the world’s first approved treatment for functional dyspepsia diagnosed by Rome III criteria, with its first approval occurring in Japan. Phase III trials in this patient population are in preparation in Europe, with phase II trials completed in the USA and Europe.

Abstract
A three-step synthesis of acotiamide
is described. The agent is marketed in Japan for treatment of patients
with functional dyspepsia. We designed a one-pot method to prepare the
key intermediate 5a from 2 via an acyl chloride and amide and then reacted with 6 to obtain 1 under solvent-free condition. With the use of DCC, the unavoidable impurity 5b was also successfully converted into the desired 1. After isolation of 1,
we carried forward to the next step of HCl salt formation, which was
proved to be a very effective procedure for the removal of practically
all major impurities. The process is cost-effective, simple to operate,
and easy to scale-up.

Approval in Japan for Treating Functional Dyspepsia with Acofide®
Press Release
Tokyo, March 25, 2013 – Zeria Pharmaceutical Co., Ltd. (Tokyo: 4559; “Zeria”) and Astellas Pharma Inc. (Tokyo: 4503; “Astellas”) announced today that as of March 25, Zeria has obtained the marketing approval of Acofide® Tablets 100mg (nonproprietary name: acotiamide hydrochloride hydrate; “Acofide”; Zeria’sdevelopment code: “Z-338”; Astellas’s development code: “YM443”) for the treatment of functional dyspepsia(FD) from the Ministry of Health, Labour and Welfare in Japan. Acofide has been co-developed by both companies.
Acotiamide hydrochloride hydrate is a new chemical entity originated by Zeria, and inhibits peripheralacetylcholinesterase activities. Acetylcholine is an important neurotransmitter to regulate gastrointestinalmotility, and through the inhibition of degradation of acetylcholine, Acofide improves the impaired gastricmotility and delayed gastric emptying, and consequently the subjective symptoms of FD such as postprandialfullness, upper abdominal bloating, and early satiation.
Acofide, the world first FD treatment which demonstrated efficacy in the patients with FD diagnosed by the Rome III, will be launched in Japan ahead of the rest of the world.Also, since Acofide will be the first treatment with FD indication, Zeria and Astellas will co-promote Acofide for the sake of the increase of disease awareness of FD, the prompt market penetration, and the maximization of product potential.
In March 2008, Zeria and Astellas concluded the agreement for the co-development and co-marketing of Acofide and, subsequently conducted the co-development. In September 2010, Zeria submitted the application for marketing approval to the Ministry of Health, Labour and Welfare in Japan.
We believe that Acofide will contribute to alleviate the subjective symptoms and improve QOL of patients with FD.
Summary of Approval
Product name: Acofide® Tablets 100mg
Nonproprietary name: Acotiamide hydrochloride hydrate
Formulation: Tablet
Indication: Postprandial fullness, upper abdominal bloating, and early satiation due to functional dyspepsia
Dosage regimen: Normally in adults, 100mg of acotiamide hydrochloride hydrate is taken orally three times per day before a meal.
About Functional Dyspepsia (FD)
According to the Rome III, FD is a gastrointestinal disease comprised of subjective symptoms including postprandial fullness, early satiation and epigastric pain without any organic abnormality on gastrointestinal tract. The etiology of FD is still unclear, but it has been shown that delayed gastric emptying is closely associated with FD.

Acofide has been co-developed by both companies.
Acotiamide hydrochloride hydrate is a new chemical entity originated by Zeria, and inhibits peripheralacetylcholinesterase activities. Acetylcholine is an important neurotransmitter to regulate gastrointestinalmotility, and through the inhibition of degradation of acetylcholine, Acofide improves the impaired gastricmotility and delayed gastric emptying, and consequently the subjective symptoms of FD such as postprandialfullness, upper abdominal bloating, and early satiation.
Acofide, the world first FD treatment which demonstrated efficacy in the patients with FD diagnosed by the Rome III, will be launched in Japan ahead of the rest of the world.Also, since Acofide will be the first treatment with FD indication, Zeria and Astellas will co-promote Acofide for the sake of the increase of disease awareness of FD, the prompt market penetration, and the maximization of product potential.
In March 2008, Zeria and Astellas concluded the agreement for the co-development and co-marketing of Acofide and, subsequently conducted the co-development. In September 2010, Zeria submitted the application for marketing approval to the Ministry of Health, Labour and Welfare in Japan.
We believe that Acofide will contribute to alleviate the subjective symptoms and improve QOL of patients with FD.

About Functional Dyspepsia (FD)
According to the Rome III, FD is a gastrointestinal disease comprised of subjective symptoms including postprandial fullness, early satiation and epigastric pain without any organic abnormality on gastrointestinal tract. The etiology of FD is still unclear, but it has been shown that delayed gastric emptying is closely associated with FD.
