Abstract:
A pharmaceutical composition comprising agomelatine is provided to be used for treating generalized anxiety disorder and provide good acceptability profile to patients without side effects such as withdrawal symptoms occurring when being treated by using a conventional psychotropic drug stops. A pharmaceutical composition for treating generalized anxiety disorder comprises agomelatine or N-[2-(7-methoxy-1-naphthyl)ethyl]acetamide, or a hydrate thereof, or a pharmaceutically acceptable acid or base addition salt thereof, and at least one pharmaceutically acceptable excipient thereof.
Abstract:
Compounds of formula (I), of trans relative configuration: in which: X is an oxygen atom or an NR 2 group, Y is a group selected from -CH 2 -, -(CH 2 ) 2 - and -CH=CH-, R 1 and R 2 , which may be identical or different, are each a hydrogen atom or a group selected from alkyl, cycloalkyl and cycloalkylalkyl, in racemic form or in the form of optical isomers, and also addition salts thereof with a pharmaceutically acceptable acid and hydrates thereof. Said compounds are useful as dopaminergic receptor ligands for the treatment of central nervous system diseases.
