PROBLEM TO BE SOLVED: To provide a compound represented by formula (I) and usable for treatment of melatoninergic system-associated disorder, and to provide a method for producing the compound and a pharmaceutical composition. SOLUTION: The pharmaceutical composition contains the compound represented by formula (I), an enantiomer thereof, and an additional salt thereof with a pharmaceutically acceptable base, in combination with one or more pharmaceutically acceptable vehicle. The method for producing the compound includes carboxylating a nitrile compound corresponding to formula (I) by using dimethyl carbonate, reducing the resultant product in the presence of a hydride, and optionally separating the reduced product on a chiral column. Various kinds of medical indications including sleep disturbance are considered. COPYRIGHT: (C)2008,JPO&INPIT

摘要:
PROBLEM TO BE SOLVED: To obtain a medicament intended for the treatment of generalized anxiety disorder. SOLUTION: Agomelatine, namely N-[2-(7-methoxy-1-naphthyl)ethyl]acetamide is used for the treatment of generalized anxiety disorder. Agomelatine has an excellent receptor profile besides observed efficacy. The withdrawal syndrome observed as an adverse effect normally caused by an antipsycotic drug is not observed in agomelatine and agomelatine is used in the most suitable therapy. The medicine composition is obtained by using agomelatine, its hydrate, crystal form and an additional salt with a pharmacologically acceptable acid or a base. COPYRIGHT: (C)2009,JPO&INPIT
