Abstract
The present invention relates to new forms of co-crystals of agomelatine and p-toluenesulphonic acid, to a process for their preparation and to pharmaceutical compositions containing them. The co-crystals according to the invention have better solubility than agomelatine and are therefore more suitable for the preparation of pharmaceutical compositions. They also have better stability and purity and, moreover, are obtained by a simple process which does not include any difficult steps.
