Abstract

<P>PROBLEM TO BE SOLVED: To obtain a medicament intended for the treatment of generalized anxiety disorder. <P>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. <P>COPYRIGHT: (C)2009,JPO&INPIT

Furthermore, besides the efficacy observed in the treatment of generalized anxiety disorder, agomelatine also has a good receptive profile for patients: in particular, agomelatine lacks the side effects normally associated with psychotropic drugs. Of these effects, withdrawal syndrome, which is observed with classic psychotropic drugs to stop treatment, is not observed with agomelatine, making it an optimal treatment for this disease.
